Long be for I became a commercial ,and later a task vessel captain, I operated D 6 dozers in spring valley,and,suffering,n y back in 1966 ultimately graduating to the then new D8 h hydroxide ,finish grading the st.Thomas,virgin islands airport to accommodate the new 727 pax aircraft . I started flying when I could not get in the operating engineers union . Those caterpillar days were a w/o fearfully time in my life .thank you caterpillar corp for such fine machines !
I drove a D7G when I was 14. My folks were building their house and the guy was digging out for the pool, and I was riding around on my little dune buggy; he says, "I'll let you drive this if I can drive that"! I did three or four scoops with him on helping then he let me do a couple by myself!!
Are you the owner of that dozer? I built engines for CAT in the 1980's now I walk with a walking stick like the gentleman in the video.heavy machinery is in my DNA.
Man do I remember those days, as a kid sitting on the heavy equipment with my Dad starting the caterpillar road graders and bulldozers , thanks for the memories.
Boy that brings back the memories from 60 years ago, My grandpa was a Sawyer had a sawmill all his live and everyone in the family raised their kids on that mill. I remember PAP every morning starting that big cat that ran the mill, that thing would blow smoke rings when it fired off all us cousins would watch in childhood bliss. Boy those was were the days, thanks for bring back all those wonderful memories of a time long ago but as fresh today as if it were yesterday, boy has the COUNTRY CHANGED FOR THE WORSE in those short years.
Glad you liked the video, thanks for taking the time to post a comment, talking of smoke rings have a look at our Caterpillar 830M video, that blows some smoke rings on start up!! Cheers 👍
Back in 86, Grants Pass, old 38 stuck out in the woods. First job after diesel school. Pony would`t stay running. Spent two days in rain. No luck. Worked on pony carb whole day. Boss yelling. Wasting time. Finally got pony good. After many, many tries, finally got main running. Boss very, very quiet. Never yelled again.
After reading through many, many post. Piecing it all together you guys got it pretty much right. But first big mistake was he didn't use the compression release at all. That's the lever on the dash support by his right foot. You can see the control rod going to the head. 1st You turn the lever with your hand to release the compression before you do anything else. Next I didn't see him look at the oil pressure gauge at all. Sometimes it takes 30sec to a min to get the pressure up. After engaging the pony motor clutch and the oil pressure comes up then you kick the compression release with your foot to engage it followed by adding fuel if it's not to cold. As far as the trailer goes I looked at the video over and over and can't see where any damage was done to the wood at all or the trailer. If you look you can see they put plywood down before they loaded the Cat. Even after the plywood got tore up during the 90 degree turn it looks like it survived well enough to keep the grousers clear of deck. Detaching the goose neck put the front of the trailer on the ground making it more stable reducing any twist on the frame. If you look at the video you can see it looks like he may have dumped the air on the rear axles as there was very little twist or movement as the Cat point loaded the side of the trailer. I think I would have blocked under the frame to the ground in a few places and a few more for the ramp but it looks like it fared very well. Now then for all you pretty boys that wax their trailers you need to look up some videos of cross country pipeline moves on the back roads of Pennsylvania. Most of the moves are side loaded for speed and efficiency. I've even seen two side booms loaded side by side with one boom down toward the front and one toward the back. Yes it wasn't legal but that's the way it was done. They make square turns on back roads at a T intersection that I could take all your money that it couldn't be done. Road drivers. Ha!
Ah, loved that! The sound takes me back to starting our D8 14A. The main was a dream but that pony motor was always a PITA to start until we got the magneto sorted out (many years later). Thanks for taking the time to record and share, so much stuff I took for granted and never took pictures or anything.

I used to volunteer at the Antique Gas and Steam Engine Museum in Vista, CA, and we had one of these. I never worked on it--I was a steam guy--but I remember seeing on show days they'd always find a tiny girl and have her drive it in the parade (with an operator next to her at all times, of course). I just loved the way the pippy pony engine would make way for the ka-chunk of the big diesel. Starting up a steam tractor is a comparatively quiet process, at least until we get to testing the safeties, or somebody starts an argument about which beer is the best.
what a treat to find this channel.I loved those monster yellow giants. My pop and an uncle bought an army surplus cat dozer in "46.Their idea was to dig cellers in WNY state, tiny town south of BFLO.Mty older bro, a cousin and I had the job to paint it yellow,sort of yellow.I was 10 they were 14, what a summer we had.They had figured how to start the monster altho we were were told ,on pain of decapitation,to never start if unless an older cousin was with us,Who follows directions????WE had turned my grandfathers acreage into our 40 acre playground, after watching pop and uncle digging a few cellars we figured nuthing to it so we dug a pond one day.WE were grounded for a few days but by time my bro and cousin were 16 they were digging cellars and ponds for 25$, and I dug my first cellar at 14.I both stammered and had dyslexia but by time I was 16 both had receeded 90% and my DR and parents were convinced that yellow dragon as I called it was responsible,everytime I pass a yello dozer I give it a smart,sharp military salute, and say Thanks good Buddy
I'm retired after over 40 years centered around construction, everything from military projects, commercial office complex, condos, and residential homes. I most say that this "off load" was unusual to say this least ! The "bottom line" is you got the dozier off with no damages, but the trailer took a licking .
@Michael Kemp,Thanks ,we are also in the uk,if ever you down in sunny Wales give us a shout ,that old girl is now the rear tractor on the DD9/Quad trac👍
I operated one of those back in the 80s pushing cat 631 scrapers huge job in Atlanta we had 3 D9 dozers one D8k and 12 631 scrapers and 16G motor grader we moved 1 million yards of dirt for waste management’s new landfill on Moreland ave the first cell was soposed to last 30 years now it’s closed completely full and caped in half it’s life unbelievable how much trash is generated in the city of Atlanta and that was one of a lot of landfills in the area
Lol awesome, but even Santa has to move with the times, he uses the D9 to move the presents around in the summer while the reindeer are resting up!!! Glad you enjoyed, cheers 👍
Many, many years ago I lived next door to a Cat Diesel mechanic and I remembered him starting a large dozeer (unknown model, but large). He used an electric starter to start a donkey engine which turned over the main engine. Fascinating.
Afraid of nothing but a track rolling off to the inside on a steep grade but the tracks looked decent on that ole boy so he should be able to walk pretty proudly I would think
Great seeing it. When I was 17 I worked a summer in an army motor pool overseas. Got to assist the mechanic repairing a D9 along with other heavy equipment. That was in 1977.
Nice............. My Dad was a contractor in the early 50's in Kentucky winters, an old D7, pony motor, rope start, he would rap the rope on, look at me, when he said go I would squirt starter fluid in the pony motor and he would jump off the track, it started after a few tries, we would sit near the fire to stay warm for the pony motor to do it's warm it up., precocious memories... This was before 1st grade! Thanks.....
Pony, Donkey, Pup it does not matter. These big land movers had a small starter engine to get the big mover going. Absolutely big units with an innovative way of getting their push on! Very interesting.!
Ima Tumor No problems, glad you enjoyed and thanks for the comment 👍 check out some of our other videos if you liked this one, some other big old stuff in action
Dad operated one of these, it was a hard life, vibration, snakes under your seat in morning attracted to heat, driving hours to your work place. He was a prospector, opening up coal mine seams, then cleaning up when the coal was gone.
That's the way we loaded and unloaded our D8 13 A in the 60"s Crank handle to start the donkey engine, and clutch and gear engagement on 1/2 compression open and then throw the compression lever in. chug a lug and away we go! Always side loaded on 2 twenty inch square hardwood blocks, and rock her down. unless we were traveling with the scraper then it was rear trailer load and unload. Thanks for the video.
Bruce Whitham Glad you enjoyed and thanks for the comment 👍 nice to see we aren't the only ones who have unloaded a machine off the side, reading some of the comments on here it's a shooting offence for unloading off the side!!
Bostonpowercat, I've driven tractor trailer for many years. I always wanted to break into the heavy-haul world. I have hauled mining equipment as heavy as 90,000 lbs. As a driver who is concerned about his equipment, and the cost of repairs, I find it difficult to understand why he off-loaded from the side. Ya, I've see a lot of Yahoo's willing to do anything to get their tractor loaded or unloaded, but when it's my rig and I'm footing the bill for the cost of repairs and replacement it's going to be done my way or else. Not trying to be a jerk here. But I have seen some really stupid crap over the years. I am always willing to learn too, which is what I'm trying to do now.
A D 9 G is a good old tractor. It will run for ever. The RPMs are low, and the horse power is reasonable. The D9H is another story. They upped the RPMs and increased the horse power. The H engine will run for 7,000 hr (more or less) then it will need to be overhauled, and most likely need to have the block cut for a spacer under the liner. That is a 1 or 2 time deal, then you will need to cut the block into the water jacket and install a Z insert. After that, you throw the block away and start new. The D9G will just keep on chugging. They also have a magnetic oil strainer on the inlet side of the transmission oil cooler plus another one before the transmission pump. The H has only the one in front of the pump. If you loose a power train component, you will also have to change the cooler, every time.
Nice combination all in all - a King Low loader pulled by a Scania, carrying a Cat tractor. Not a sight you see every day. Love watching these as they're the only place to find this equipment these days. Love it!
I love the old pony engine Cats! My favorite is the D318 cat! 2 stroke GMs are a great sounding too. I also like the old International diesel that would fire on gas to get warmed up, then switch to diesel. These took a ton of engineering to invent. I hope these machines survive forever and avoid the scrap boat ride to China, that is ALWAYS a shame. Take care bud! ☺️😎
UnitCrane514 Your can't fault the pony engined Cats! The D318 is a good engine, but our favourite has to be the D17000!! Other manufactures have some great stuff, but we are mainly about Cat! Don't worry these won't be getting weighed in for scrap anytime soon and they should last forever, they certainly are built for it :-) Cheers
Brings back fond memories as a kid 10 years old, operation a D9, D8 and D6 at my folks material pit in East El Cajon CA. After school, my dad would have one of the drivers go and pick me up and bring me to the Pit. Operated everything, Dump Trucks, Loaders, conveyors, dozers. What a childhood. To this day I get a chance to jump on any equipment I do. Now I spend my time assessing the damage caused by the poor operation, operator error, fire cause & origin, any loss that happens to any type of equipment.
@Ted Aufort great to hear your memories of the old stuff ,that’s what really interests me other peoples experiences and memories of this old equipment . Many thanks👍
@@Bostonpowercat That little 6 we had, had a gas-powered donkey engine that had a rope start. It was an old one but ran great, my first. This was back in 1969 and was a great 5 years. Other kids had Tonka, I skinned Cats.
Thats awesome, you don't see so many these days doing a days work now unfortunately , still a great machine, but technology moves on I guess!! Cheers 👍
@Michael Sullivan,that’s the way,same as I use mine for,have a bit of fun then put em away ,they don’t cost nothin then😂,leave the expensive running costs for the Big Boys😂👍
I've pushed scrapers with an old 9g with a peterson blade pony motor start if the pony motor cranked that beast was cranking and they were stout I often said they would push the empire state building through the gates of hell and never slow down
Tommy Rottn Great observational skills, what makes you say we are in Boston? I take it you mean Boston USA? If you notice the traffic is on the wrong side of the road for the USA!! What is sad about the video if you don't mind me asking??
Tommy Rottn Thanks for your reply, the trailer was fine, admittedly it's not ideal coming off the side, but we didn't want to take it off the back into oncoming traffic and cause an accident. Also we didn't want to chew the road up or break any kerb stones and then have to pay to get them replaced. We were also on a tight time schedule so after weighing up our options this was the way we decided to go. Cheers 👍
Loved seeing the Old-Timer giving ground-support as the cat was unloading. It reminded me of a conversation I had with a gent who was the father of the man I hired to do some dozer work on my property. As we spoke, he allowed that he served in the U.S. Army Corps of Engineers and had been part of the force that built The Burma Road, between Burma and China- one of the most remarkable feats of engineering in WWII. Men far more industrious and capable than us have preceded us. We'd be wise to take their counsel and learn from experience, often bitterly received....................
Mike Brown my Dad flew C46s in WW2 Flying the Hump in support of those guys in China , Burma , India Theaters for example he hauled fuel parts supplies & personnel for the road construction among many other things they lost many Brave Men on those Runs my Dads plane was shot thru belly & my Dad was struck in the Butt & back was not sent home fixed up & flying his next run that's how Tuff they were back then GOD BLESS ARE VETS !!
Very cool vid, thanks for posting. Loved hearing that diesel slowly come to life. Beautiful sound. Well done- clearly you guys know what you're doing. Stay safe, keep the dirt moving.
I'll bet that's as close as you'll get to the sound of a WWII tank without having an actual tank. Wonderful old piece of equipment. Bet she can still put in the work too!
Glad to see you have seen the light and have come over to the world of Cats!! :-) It's great to have you on board 👍 They are great machines and have some real character, and that's what we are mainly interested in, from the 40's to the late 60's, have a look at our other videos, they are with machines from that era.
That dozer came with a cushion block instead of straight or U blade. For pushing scrapers. This machine was same as one I ran on Trans Alaska Pipeline on Gobblers Knob. This unit would have a strong final drives as there was no ripper on it.
@@AlaskaDanger-jf6ti you are spot on mate ,that’s why we got her no hydraulics no rippers !, they destroy tractors! in wrong hands.That old D9 is now the rear tractor on our Quad 9 👍
I learned to use a dozer on a Euclid C6 with a rope lifted blade. Very noisy GM 6 cyl when you take your foot off and call up full power but a wonderful machine. I.was 19 then
I started working for caterpillar dealers when I got out of the army in ‘78. The old D8’s and D9’s all had the pony motors. Some even had a rope to start it. Had a compression release to get the engine turning and were all direct drive with a clutch lever. The good old days.
Operated some highly modified D9’s in Greenland in 67. Stretched frames, 55 inch wide track pads, some had 600 gallon nose tank, 300 gallon belly tank, and a 150 in the rear. Others had 14 foot wide blades.. dragged some very, very heavy and long loads over the ice cap. YT search Camp Century to get a view of some of them at work.
PnF ottjed In response to your comment that wood decking is cheaper than pavement we would have to totally agree and that's why we unloaded it that way. Thanks for your comment :-) (There was no reply option on your comment so had to write a separate comment)
Bostonpowercat Good Lord! I don't even see how the wood could have survived carrying that beast! I know very little about heavy equipment, (although, I am an Auto mechanic), and I do realize that, for the sake of self embarrassment, that knowledge between the two differ greatly! I have read a lot of magazines about gasoline engines being used as a starter for the Diesel engine itself, and then the shutting down of the Gasoline starter engine? Is this the case? (Obviously there are two engines!) I just really wanted to better understand these things, since I am so inclined! Thank you!
Shawn Aloia There also were engines that had spark plugs in the cylinders. The engine started up as a gasoline engine then after it warmed up you swapped the gasoline throttle and the diesel throttle. One Engine that could run on gasoline and diesel.
Kinda got that, and kinda didn't, LOL! Do you mean that a single engine could run on both gasoline, and diesel? Or, are you referring to my thought as the gas engine acting as the "starter" for the diesel, that would ultimately drive the machine? (I just find these old machines to be amazing!) Thanks, in advance, BTW!
Shawn Aloia Hey :-) No need to be embarrassed, glad you stopped by and great to see someone who admits to not knowing everything and is willing to ask to find out more! Yes you are right, there are 2 engines, a small gasoline engine called a pony motor (or sometimes called a donkey engine depending where in the world you are from) which is then used to start the main big diesel engine. Up until very approximately the late 1960's it's the only way you could start these machines via the smaller pony motor! Back in the day batteries and starter motors just weren't up to the job of turning of these massive engines. It also meant the main engines didn't need glow plugs as the main engine is turned over on decompression for a few minutes which warms it up before finally switching it over to compression where upon it fires up. Hope this makes sense and has answered your question, anything else we will be happy to try and help if we know the answer! Cheers
Richard C In the U.K we call it a donkey engine and it runs on petrol not gas, gas to us is a vapour not a liquid, but these are just some of the difference in the American/English language
Yes my ex is from Liverpool. Know the difference. Spanner / wrench Bonnet, hood, windscreen,windshield. Her father was from Wales, I never could understand him.
My Dad bought a new one in the 60's. Cushion pusher blade. I would run it when the operator failed to show on time. Didn't like pushing scrapers. We had two D8s and a TD25 for dozing.
Loaded and unloaded all the time over the side of an old Hamilton lowboy, pulled with a Diamond T with a 220 Cummings in it, you didn't miss much scenery. Tractors had root plow on the back and a stacker or dozer on the front, both A IH TD25 and D82U the 25 would just barely fit and you had to turn it just at the right moment
+James Hurlbut ahh someone else with some sense, but don't tell people you unloaded off the side of the lowboy, they will be out to linch you!! So many people commenting about how it's wrong to come off the side, it's not ideal, but in this situation it was the best option. Great to hear from someone who used to be around the old stuff, what were you doing with the 2U? You still involved in the plant world? Cheers
Thanks a lot! Never saw a "low loader. I grew up around a D2. We called the "donkey start" a "pony motor," which had a rope starter. What a sight and sound of this beast getting going. It reminds me of the B-29 (et. al.) rotary engines starting up on the tarmac.
At the company I work for sometimes I have to run an old d8 h model that was converted to electric start from a pony motor. I gotta say I’m thankful that we only have of those flat track dosers. I’ll take a d8 n or r any day
Actually common on older machines. I had a 50 hp International D8 that had the same set up. A very cool machine. (until I ran over a nasty wasp hive one day)
I have done heavy haul for 40 years a good way to get one off the trailer if you have a bunch of old tires you can lay them down and run over them will not hurt the pavement have crossed a highway too that way have also used street plates on the trailer bed but that's very slick steel on steel will slide easy .
John Siders thats how we did it plowing fiber optic cable when we had to jump around a creek or driveway we would use old tires to tire the cats across. works like a charm
There goes the cucumber kitty again! Sweet old 9. Needs a cushion rock blade to keep the boredom away. I wouldn't mind shoving a pan or two, bored or not! Good One!
Lol, yeah no hydraulics on this one, just used as a pusher. Having a fleet of scrapes flying in waiting to get pushed and loaded would keep the boredom away!!
Never heard the term "donkey start" before. Now I understand. What happens when the starter motor won't start? lol Looks like a lumbering giant from yesteryear for sure. Cheers from Louisiana.
In the cold country, you could use the pony motor to warm the engine some, it uses the same motor oil and coolant systems, at least the old D7 I worked with at a mine in Alaska did. But I was a lot younger then and I don't have a pony motor to get me warmed up and started so I left the cold country.
On the job I was on in Northern Ontario, we had one of those and in the late fall and winter months it ran 24/7 unless it was taken into the heated shop for maintenance. The reason was that once you shut it off in the cold weather for even a few hours, the donkey engine was never strong enough to start in again.
@Roland Vachon,Thankyou for info,that sounds too cold for me!,I always wonder how many opperators would have to use the low range on the donkey gear box ,be rare over here in the uk.👍
Happy days, i was a mechanic/fitter back in the 70s for a cat dealer.

Lol awesome, but even Santa has to move with the times, he uses the D9 to move the presents around in the summer while the reindeer are resting up!!!
Glad you enjoyed, cheers 👍
Hahaha, Yes i agree.
Thank's for sharing.
Many, many years ago I lived next door to a Cat Diesel mechanic and I remembered him starting a large dozeer (unknown model, but large). He used an electric starter to start a donkey engine which turned over the main engine. Fascinating.
I push pans with one of these building I-40 @ Mocksville NC
donkey engine you mean pony motor....
@@johnsmith-oh2xodepends where in the world you are. UK it's Donkey engine.
It was like watching a prehistoric dinosaur walk back into the woods!
Slow and steady, knowing he owns the woods and not afraid of anything!
EXACTLY !
Afraid of nothing but a track rolling off to the inside on a steep grade but the tracks looked decent on that ole boy so he should be able to walk pretty proudly I would think
Great seeing it. When I was 17 I worked a summer in an army motor pool overseas. Got to assist the mechanic repairing a D9 along with other heavy equipment. That was in 1977.
Nice............. My Dad was a contractor in the early 50's in Kentucky winters, an old D7, pony motor, rope start, he would rap the rope on, look at me, when he said go I would squirt starter fluid in the pony motor and he would jump off the track, it started after a few tries, we would sit near the fire to stay warm for the pony motor to do it's warm it up., precocious memories... This was before 1st grade! Thanks.....
Pony, Donkey, Pup it does not matter. These big land movers had a small starter engine to get the big mover going. Absolutely big units with an innovative way of getting their push on! Very interesting.!
Man, that thing is a beast. Clanking and chugging and rumbling along. Thank you for the great video

Oh boy 😝,,, I likey D9,, that's about where dozers start getting ,,,,, you know BIG ✌️
Dad operated one of these, it was a hard life, vibration, snakes under your seat in morning attracted to heat, driving hours to your work place. He was a prospector, opening up coal mine seams, then cleaning up when the coal was gone.
What a kick! Love the sound of her! Good job filming. And thanks for sharing!
That's the way we loaded and unloaded our D8 13 A in the 60"s Crank handle to start the donkey engine, and clutch and gear engagement on 1/2 compression open and then throw the compression lever in. chug a lug and away we go! Always side loaded on 2 twenty inch square hardwood blocks, and rock her down. unless we were traveling with the scraper then it was rear trailer load and unload. Thanks for the video.
Bruce Whitham Glad you enjoyed and thanks for the comment 👍 nice to see we aren't the only ones who have unloaded a machine off the side, reading some of the comments on here it's a shooting offence for unloading off the side!!

Bostonpowercat, I've driven tractor trailer for many years.
I always wanted to break into the heavy-haul world. I have hauled mining equipment as heavy as 90,000 lbs.
As a driver who is concerned about his equipment, and the cost of repairs, I find it difficult to understand why he off-loaded from the side. Ya, I've see a lot of Yahoo's willing to do anything to get their tractor loaded or unloaded, but when it's my rig and I'm footing the bill for the cost of repairs and replacement it's going to be done my way or else.
Not trying to be a jerk here.
But I have seen some really stupid crap over the years.
I am always willing to learn too, which is what I'm trying to do now.
@@mebcool Maybe to not damage the roadway?
I never get tired of looking at this video. I wish you still made them.
All the best.
@Military Museum👍
I love watching those old D9s and someone who really knows how to jockey one !
I notice just how much respect the oncoming traffic gave these people at the start of this video. None.
Great video, love the old flat track D9s, very powerful machines in their day.
That old timer with the cane is re living some memories for sure i bet he could run it better than anyone involved with this video
oh yeah
What a beaut beast of a Cat D9G. A sensational video

A D 9 G is a good old tractor. It will run for ever. The RPMs are low, and the horse power is reasonable. The D9H is another story. They upped the RPMs and increased the horse power. The H engine will run for 7,000 hr (more or less) then it will need to be overhauled, and most likely need to have the block cut for a spacer under the liner. That is a 1 or 2 time deal, then you will need to cut the block into the water jacket and install a Z insert. After that, you throw the block away and start new. The D9G will just keep on chugging. They also have a magnetic oil strainer on the inlet side of the transmission oil cooler plus another one before the transmission pump. The H has only the one in front of the pump. If you loose a power train component, you will also have to change the cooler, every time.
What a Monster ! Grettings from Germany
They where a real work horse in its day! Well still are! Remember them well! Thanks for sharing!
Power, power and gobs of power. Love it.
Nice combination all in all - a King Low loader pulled by a Scania, carrying a Cat tractor. Not a sight you see every day. Love watching these as they're the only place to find this equipment these days. Love it!
Thanks very much, glad you are enjoying the videos, make sure subscribe to keep up with the latest releases!!

Gareth - This is one great combination --- King Low Loader, The Big Cat and a European Scania.
Real old school Caterpillar, build like a tank,I love it.
That's how my grandfather unloaded his d8 but his trailer was long never had to unhook. Great machine.
I love the old pony engine Cats! My favorite is the D318 cat! 2 stroke GMs are a great sounding too. I also like the old International diesel that would fire on gas to get warmed up, then switch to diesel. These took a ton of engineering to invent. I hope these machines survive forever and avoid the scrap boat ride to China, that is ALWAYS a shame. Take care bud! ☺️😎
UnitCrane514 Your can't fault the pony engined Cats! The D318 is a good engine, but our favourite has to be the D17000!! Other manufactures have some great stuff, but we are mainly about Cat! Don't worry these won't be getting weighed in for scrap anytime soon and they should last forever, they certainly are built for it :-)

Brings back fond memories as a kid 10 years old, operation a D9, D8 and D6 at my folks material pit in East El Cajon CA. After school, my dad would have one of the drivers go and pick me up and bring me to the Pit. Operated everything, Dump Trucks, Loaders, conveyors, dozers. What a childhood. To this day I get a chance to jump on any equipment I do.
Now I spend my time assessing the damage caused by the poor operation, operator error, fire cause & origin, any loss that happens to any type of equipment.
@Ted Aufort great to hear your memories of the old stuff ,that’s what really interests me other peoples experiences and memories of this old equipment .
Many thanks👍
@@Bostonpowercat That little 6 we had, had a gas-powered donkey engine that had a rope start. It was an old one but ran great, my first. This was back in 1969 and was a great 5 years. Other kids had Tonka, I skinned Cats.
I remember in 1984 there were still D9G Pushcats in operation in Southern California
Thats awesome, you don't see so many these days doing a days work now unfortunately , still a great machine, but technology moves on I guess!!
Cheers 👍
In Georgia a company I worked for still uses D9 push tractors. Old girl runs like a top
My dad operated for nearly 40 years. I wish I could do it but I know better than to try. I'm going to miss him.
Brings back memories with my dad putting .me in the seat in the coal fields of pa. We called the starters piney morters
You sure they wasn't called poney motors
Growing up, my best friend's dad had a CAT D9 at his ranch. He used it for Sunday drives around the ranch. Just for fun! Those were the days!
@Michael Sullivan,that’s the way,same as I use mine for,have a bit of fun then put em away ,they don’t cost nothin then😂,leave the expensive running costs for the Big Boys😂👍
Remember my father back in the late fifties had a D9 when he had his bulldozer business. He could sure work that machine .
I've pushed scrapers with an old 9g with a peterson blade pony motor start if the pony motor cranked that beast was cranking and they were stout I often said they would push the empire state building through the gates of hell and never slow down
That’s so fascinating, wish I would’ve been around in times to see that
I'm glad you guys are in Boston - and not any where near me. This is just sad, and the fact that you are proud of it, makes it even sadder. :(
Tommy Rottn Great observational skills, what makes you say we are in Boston? I take it you mean Boston USA? If you notice the traffic is on the wrong side of the road for the USA!! What is sad about the video if you don't mind me asking??
I was mainly concerned with the side unload and tearing up the trailer decking. Highly unsafe.
Tommy Rottn Thanks for your reply, the trailer was fine, admittedly it's not ideal coming off the side, but we didn't want to take it off the back into oncoming traffic and cause an accident. Also we didn't want to chew the road up or break any kerb stones and then have to pay to get them replaced. We were also on a tight time schedule so after weighing up our options this was the way we decided to go.
Cheers 👍
Tearing up the road and the kerb are good points I hadn't thought of. Be safe and cheers.
+Tommy Rottn no problems at all
Thanks for taking the time to comment 👍
Loved seeing the Old-Timer giving ground-support as the cat was unloading. It reminded me of a conversation I had with a gent who was the father of the man I hired to do some dozer work on my property. As we spoke, he allowed that he served in the U.S. Army Corps of Engineers and had been part of the force that built The Burma Road, between Burma and China- one of the most remarkable feats of engineering in WWII.
Men far more industrious and capable than us have preceded us. We'd be wise to take their counsel and learn from experience, often bitterly received....................

I've always been a train guy but I really do like these older cats especially ones made in between the 40's and late 60's
Glad to see you have seen the light and have come over to the world of Cats!! :-) It's great to have you on board 👍
They are great machines and have some real character, and that's what we are mainly interested in, from the 40's to the late 60's, have a look at our other videos, they are with machines from that era.
That machine needs a channel of it's own. What a great beast!
@DingleZilla,Cheers 👍👍👌
When it goes off into the woods it reminds me of a tank in WWII

I drove a D9G for a while and just loved how it rattled and shook when started on a cold frosty morning.
It sounds good! What I was told they could blade through 2ft of frost easy.
That dozer came with a cushion block instead of straight or U blade. For pushing scrapers. This machine was same as one I ran on Trans Alaska Pipeline on Gobblers Knob. This unit would have a strong final drives as there was no ripper on it.
@@AlaskaDanger-jf6ti you are spot on mate ,that’s why we got her no hydraulics no rippers !, they destroy tractors! in wrong hands.That old D9 is now the rear tractor on our Quad 9 👍
I dont know why i came back to see this video for the 3rd time. Its really fascinating
Always welcome to watch a forth 👍👍
I learned to use a dozer on a Euclid C6 with a rope lifted blade. Very noisy GM 6 cyl when you take your foot off and call up full power but a wonderful machine. I.was 19 then
I started working for caterpillar dealers when I got out of the army in ‘78. The old D8’s and D9’s all had the pony motors. Some even had a rope to start it. Had a compression release to get the engine turning and were all direct drive with a clutch lever. The good old days.
@Kirby Morris ,yes they are great Cats from that era certainly built to last,would like to get hold of a direct drive D9 18a one day.Cheers.
Operated some highly modified D9’s in Greenland in 67. Stretched frames, 55 inch wide track pads, some had 600 gallon nose tank, 300 gallon belly tank, and a 150 in the rear. Others had 14 foot wide blades.. dragged some very, very heavy and long loads over the ice cap. YT search Camp Century to get a view of some of them at work.
Will do. Thanks.
Geo Thomas we didn’t have any roads
Bloody beautiful 9ld machines.
PnF ottjed In response to your comment that wood decking is cheaper than pavement we would have to totally agree and that's why we unloaded it that way. Thanks for your comment :-)
(There was no reply option on your comment so had to write a separate comment)
Bostonpowercat Good Lord! I don't even see how the wood could have survived carrying that beast!
I know very little about heavy equipment, (although, I am an Auto mechanic), and I do realize that, for the sake of self embarrassment, that knowledge between the two differ greatly!
I have read a lot of magazines about gasoline engines being used as a starter for the Diesel engine itself, and then the shutting down of the Gasoline starter engine? Is this the case? (Obviously there are two engines!) I just really wanted to better understand these things, since I am so inclined!
Thank you!
Shawn Aloia There also were engines that had spark plugs in the cylinders. The engine started up as a gasoline engine then after it warmed up you swapped the gasoline throttle and the diesel throttle. One Engine that could run on gasoline and diesel.
Kinda got that, and kinda didn't, LOL! Do you mean that a single engine could run on both gasoline, and diesel? Or, are you referring to my thought as the gas engine acting as the "starter" for the diesel, that would ultimately drive the machine? (I just find these old machines to be amazing!)
Thanks, in advance, BTW!
Shawn Aloia Single engine that ran on both fuels.
Shawn Aloia Hey :-) No need to be embarrassed, glad you stopped by and great to see someone who admits to not knowing everything and is willing to ask to find out more!
Yes you are right, there are 2 engines, a small gasoline engine called a pony motor (or sometimes called a donkey engine depending where in the world you are from) which is then used to start the main big diesel engine. Up until very approximately the late 1960's it's the only way you could start these machines via the smaller pony motor! Back in the day batteries and starter motors just weren't up to the job of turning of these massive engines. It also meant the main engines didn't need glow plugs as the main engine is turned over on decompression for a few minutes which warms it up before finally switching it over to compression where upon it fires up.
Hope this makes sense and has answered your question, anything else we will be happy to try and help if we know the answer!
Cheers
I ran a D-9 back in the 70s pushing pans in the bar pit, it was a dang man too

RGN...removable goose neck...
The sound of that pony sure takes me back...
i was a field service mechanic and we called that a pony motor. 2 cylinder gas engine turns over the Cats diesel engine so you can fire it off.
Richard C In the U.K we call it a donkey engine and it runs on petrol not gas, gas to us is a vapour not a liquid, but these are just some of the difference in the American/English language
Yes my ex is from Liverpool. Know the difference. Spanner / wrench

She IS A BEAUTY! The ole pony motor trick!
My Dad bought a new one in the 60's. Cushion pusher blade. I would run it when the operator failed to show on time. Didn't like pushing scrapers. We had two D8s and a TD25 for dozing.

Loaded and unloaded all the time over the side of an old Hamilton lowboy, pulled with a Diamond T with a 220 Cummings in it, you didn't miss much scenery. Tractors had root plow on the back and a stacker or dozer on the front, both A IH TD25 and D82U the 25 would just barely fit and you had to turn it just at the right moment
+James Hurlbut ahh someone else with some sense, but don't tell people you unloaded off the side of the lowboy, they will be out to linch you!! So many people commenting about how it's wrong to come off the side, it's not ideal, but in this situation it was the best option.
Great to hear from someone who used to be around the old stuff, what were you doing with the 2U? You still involved in the plant world?

We called them "pony motors" great setups !
Thanks a lot! Never saw a "low loader. I grew up around a D2. We called the "donkey start" a "pony motor," which had a rope starter. What a sight and sound of this beast getting going. It reminds me of the B-29 (et. al.) rotary engines starting up on the tarmac.
Warren - We in The Great White North (Canada) call these starter motors pony motors.
At the company I work for sometimes I have to run an old d8 h model that was converted to electric start from a pony motor. I gotta say I’m thankful that we only have of those flat track dosers. I’ll take a d8 n or r any day
When your engine is such a beast that it takes a starter to start the engine that starts your engine.
Actually common on older machines. I had a 50 hp International D8 that had the same set up. A very cool machine. (until I ran over a nasty wasp hive one day)
Jet aircraft still use this method for large engines. Electric starter/generators are typically found on small ones though
I bet the delivery guy was thrilled with you!
Surely,the flashing light on the tractor should be IN FRONT of the aerofoil?
Some have them fitted like to warn drivers approaching from rear, there are probably warning lights to the front.
Yeah there's other flashing lights...
I have done heavy haul for 40 years a good way to get one off the trailer if you have a bunch of old tires you can lay them down and run over them will not hurt the pavement have crossed a highway too that way have also used street plates on the trailer bed but that's very slick steel on steel will slide easy .
Thanks for the comment and some very sound advice, luckily it's not a regular occurrence, but definitely one to bear in mind 👍
John Siders thats how we did it plowing fiber optic cable when we had to jump around a creek or driveway we would use old tires to tire the cats across. works like a charm
The old man is prime example of what u look like after u operate one for 50 years.try a td 20 .that is a machine..
I do and it was. UD start.
The lowboy trailer is a marvel of engineering in itself.
The operator had to be as careful of grandpa as his job unloading the D9. Gramps just wanted to help...
There goes the cucumber kitty again! Sweet old 9. Needs a cushion rock blade to keep the boredom away. I wouldn't mind shoving a pan or two, bored or not! Good One!
Lol, yeah no hydraulics on this one, just used as a pusher. Having a fleet of scrapes flying in waiting to get pushed and loaded would keep the boredom away!!
Never heard the term "donkey start" before. Now I understand. What happens when the starter motor won't start? lol Looks like a lumbering giant from yesteryear for sure.
Cheers from Louisiana.
I always knew them as pony motors
Donkey engines here in the UK
I always wanted to see a D9 Side x Side.
In the cold country, you could use the pony motor to warm the engine some, it uses the same motor oil and coolant systems, at least the old D7 I worked with at a mine in Alaska did. But I was a lot younger then and I don't have a pony motor to get me warmed up and started so I left the cold country.
That guy looks tiny on top of that thing 😂 amazing!
They were one of the largest dozers of their time and still command a lot of respect these days.
On the job I was on in Northern Ontario, we had one of those and in the late fall and winter months it ran 24/7 unless it was taken into the heated shop for maintenance. The reason was that once you shut it off in the cold weather for even a few hours, the donkey engine was never strong enough to start in again.
@Roland Vachon,Thankyou for info,that sounds too cold for me!,I always wonder how many opperators would have to use the low range on the donkey gear box ,be rare over here in the uk.👍
