- Don Hunter's Holt tractor is a replica of a 1906 steam-powered crawler tractor. The only original part is the crankshaft; everything else Don scaled to size off some drawings and some pictures and manufactured everything else, except the boiler.
Don started this project after he retired. It took him roughly 8 years to complete (correction to my data at the end of the video) - ยานยนต์และพาหนะ
I have seen this crawler up close an exact reproduction of the first Holt machine. The front wheel will turn but the tracks do have steering clutches. This was a innovation by Holt and used first on his wheeled machines. Later they found out that the front wheel was not needed, making the crawler design you see today. Holt merged with Bess to create Caterpillar tractors. This one is run with a steam engine as were the first ones until Holt started using gas engines. A fantastic build. Phil
Don has done a wonderful job replicating the original Holt crawler. I know he worked on building it for many years.
I've seen old pictures of a Holt steam powered crawler when I was very young. It's truly wonderful to see one actually working. Well Done Mr. Hunter!
We have a couple pictures on the walls at the Cat dealer I work at, this looks very accurate to them, what a good job on re-creating one of the most important pieces of equipment ever devised. Holt / Best = Caterpillar, which changed, and still is, changing the world. No matter what company builds the machine, or what color it's painted, people call a bulldozer a "cat"
I've always found steam tractors fascinating. Good video!
Thanks!
What an impressive sight that is, beautifully restored and working well.
PriestmanCub Actually, it's a full-scale replica, not a restoration. However, the guy who built it told me several years ago at the Great Oregon Steam-Up that it does incorporate a few original Holt components that he was able to procure.
Excellent replica! Those were some amazing looking traction engines, and it was a real shame none survived. Thanks for bringing back some steam history, first caterpillar tractor!
Never knew there were steam powered Holts!
Son they’ll never replace the horse.
2:20; "Junior, meet great-great grandpa Holt!"
Yea track tracktors are a lot different now☺️
The size is amazing and ridiculous at the same time.
Incredible re-creation. Designed to operate on "Tule" soil that wouldn't support the weight of a team of horses, even with special large horseshoes. And they hadn't figured out how to steer a caterpillar machine by braking one track, hence the nose wheel.
Very interesting
This is a full scale replica
Wonderfull and historic ..... the legend of the genie.... Bravo.. for alls.. JB.
An osha nightmare and a thing of beauty all in one package. A lot of work must have gkne into it.
When men were men and boys were boys..
Steem always amasing to see and so mutch power
GREAT SHOW!!!!
Very nice job he did. I saw this in person last year at the bsot in woodland ca
awesome video
Good job on your video I liked it very much!
very nice!!
Great Job,
Let's get that at the Great Dorset Steam Fair!!!!
When steam was King!
Behold, the world's largest steam dome.
I assume the vertical cylinder is the boiler. Seems to me there is very little clearance between the road and the bottom of the boiler. Going over a small bump could result in destroying the boiler and scalding the rider. Very impressive though.
nice my great grandfather had a holt tractor with a 12 bottom plow
What a contraption, I can't imagine cultivating a 25 acre field with that. I guess it was better than a horse though.
Is this at Del Mar? I could have sworn I've seen that tractor at the Gas & Steam Engine Show in Vista.
+Brian Liesberg To my knowledge, it's never been down at Vista
I'd love to see that thing plow
What a strange creature this is! Never seen a traction engine like this in all my years at "Rough and Tumble" in Pa. I see a piston and a boiler so I have to assume it's steam but it's burning what? Oil or gas or kerosene? My neighbor needs some yard work done.... maybe I can rent you for a couple or hours? :)
Note: Does not turn on a dime.
Bueno, almenos valieron para llegar a dónde han llegado las modernas de hoy...😀
Se oye de fondo la canción the kids aren't alright de the Offspring?
The tracks do not turn at different speeds and do not turn the machine. The frontwheel turns the machine.
What's the maximum RPM on that traction engine?
Beautiful piece of machinery, Thank You! But one could see why Holt/Caterpillar went over to the IC engine in 1906.
The steamer just does not have the horsepower. It's too slow and heavy and would be able to make it up even a slight grade with a load.
Obviously you've never witnessed a steamer at a tractor pull. They may be slow and heavy, and not rated very high in terms of horsepower, but they have a ton of torque and it's damn near impossible to stop one. Can't make it up a slight grade? They could climb a mountain if they could find traction.
I don't understand how this machine turns. The two tracks are running at different speed, that is visible. That's how a tank would turn, but what on earth is that front wheel doing then? Someone please enlighten me :) Fascinating machine though!
J'ai posé une question!!!.... sur ces images on voit très bien les raisons de........
Where can I find the design plans so I can build my own?
Google....
@@reddirtfarm7704 Ah yes, Google, lets see.
*Googles Holt steam tractor design plans*
Hmm, articles on its history, neat, *scrolls down* more articles, *scrolls down* even more, hmm, still no plans. *Switches to image search*
Ah, we got some general elevation drawings, and that's about it.
Google is a great tool, but you often need specific key words in order to find specific information, such as the website name that contains the plans, _if_ they're even online.
Thank you for this brilliant revelation after 12 years.
@@DAKOTA56777 definitely joking!! But if i was serious about building one . I would have bought some parts from the Irvin Baker collection sale that Aumann's had a few months back. But I've got enough crawlers and collector tractor's.
So how the heck do ya fire it? I'm going to assume that it burns oil.
michigandon it runs on coal
No is not oil is steam.
The front wheel is about 30 in. Dia. En 4 wide w/ holes on center and then you stick a long round bar and fire up the motor...by hand.....
@@alejandroleal9493 WRONG.
It could be a steam tank XD
is this orgiinal or replica
Knowing my luck, I'd stall the engine, and then fall backwards into the gear behind the driver, then roll off onto the ground to be ran over by the plow :).
Nice video. Too bad it couldn't pull a period plow...
😲

At least I know my family name still thrives in some parts of history in the united states.
Are you related to the founder of Holt tractors?
Question ...: pourquoi ce tracteur fabuleux avait'il une roue devant????....... ils avaient un problème!!... laquel???... . Pourquoi par la suite ils ont supprimé la roue??....... ils avaient résolu le problème!!... comment..????? By
I think Don burns diesel in his tractor
Do you have any DVDs of your work? How could I contact you?
Is your question directed to the tractor builder or the videographer?

I contacted him and left a message, but never heard back from him. Oh well.
Another 200 years in the future the Amish will finally give up farming with horses and mules and adapt this latest technology. While the rest of us will be driving flying cars and satellite self navigating farm tractors and robots doing the farm work.
