You'd be a great shop class teacher. We learn and retain info best when we are laughing.
He does make a lot of his lessons funny
True !!!
Taryl is like twenty some steps ahead of any high school shop teachers I've ever met. I work off and on as substitute teacher here and not even in my area where I live. I at an inner city school near Reading Pa... I want to tell ya the school board is probably only capable of running a liquor store and that's about the extent of their knowledge. When I said that at meeting about 2-3 years ago it was one of more infamous smart ass comments people still remember me by that zinger because people and parents were spitting coffee all over each other laughing their asses off. People wanted me to run for an open position on their school board. I said within a week I would end up earning a lifes sentence at the state pen....
I've ran crews and trained guys in electrical, welding and ironworking and mainly air conditioning, now retired. I was always calm and cool and I had really great results in training but, I never thought about adding humor. It immediately makes sense. You sir are a genius.
My wife heard when you threw the belts on the floor and started fussing, she said "that sounds like you honey lol!" I had to replay it for her to see and she said "yep, that's you!" LOL
Lol... mine said samething
Just get out the duct tape and tape it back together...
Nope just wait till you try to take the blade off an old brush hog. Agony and you’ll immediately wish you were messing with a lawnmower
When we get older and fatter our belts break lol.
Thanks, you just can't beat experience. That's why we're here, to get the knowledge you share with us. A thumbs up friend!
I just broke a belt on a brand new mower with less than one hour mowing. Now I know why. I was cutting really thick grass which is now under the cut grass, and then driving into an area that the grass is already cut and cleared. The belt was snapping as Taryl said. I didn't hear it or feel it but it had to be happening if Taryl said so. Now I should be getting a long use from my belts if I cut the grass the right way. Don't cut grass on top of uncut grass. Cut grass onto already cut grass. Now off to the store to get a new belt. Thanks Taryl. We're never too old to learn.
This guy explains things exactly how it needs to be done.
Thank you Taryl , you help us out so much with these videos. Thanks for saving us money.
Awesome segment!
Reminded me of my Bolens ST180 hydro that used to go through belts like CRAZY, but only when I would have to raise the deck with the PTO on to get over rises, squirrels, etc. Turns out I had a burr on the bottom of one of the pulleys that would just slice em up if the angle of the belt came close to parallel with the PTO pulley.
I had a Bunton mower years ago that wore those drive belts out like you mentioned. Wish I hadn't sold it. Got lucky and found a set of original equipment belts when I rebuilt my deck. Had been shredding belts. Now I know why. Cuts nice again for a 21 year old Craftsman. Thanks for another great video.
another great video Taryl.
i was given a Murray 38702x20c recently, and was told it just needed a bushing for a front wheel, i was later told it chewed up belts super fast.
it's currently stripped down completely, there are four belt guides at the front, and three on the rear, 6 were bent and grooved from rubbing on the pulleys.
the main frame assembly had patches welded on each side where the trans-axle bolted on, both patches were broken, so it was only held onto the mower with the brace near the brake disc, the reason for the strip down is a dozen cracks, someone way too heavy owned it in the past.
the deck is pretty bad, but i might be able to repair it, at worst the mower can be a tow vehicle for the firewood cart or the lawn sweeper.
regards from Australia.
Great info Taryl and entertaining as always! Once while cutting the grass I noticed that awful smell of burning rubber. Shut it down , checked it out, and found the idler pulley was not turning.. seized bearing.
You must be psychic! My mower is about 10 years old and my belt broke Wednesday afternoon 8-19-20! I am planning on putting it on today! So here's my dinner!!
Good luck what kinda mower do you have
@@hunter7476 TORO TITAN Z 5200. Earlier this spring, I took care of a Fluffy problem.Taryl truely fixes all!
I really. Love all your videos you have help me fixs lot of mowers. I been work on mowers for people. Over36 years. New mowers lose me you videos are the best keep up that grateful. For you i your biggest fan
Also, to help prolong the life of your deck belts engage them at low speed before throttling up to mow. Every time you engage, you get slip. Every slip equals wear. The lower the RPM, the less slip ergo less wear and longer life.
And don't just slam it into operation. Ease into the engagement so you don't shock the belt having it go from 0 to full speed suddenly.
Wrong the pto is designed to start at full throttle! If you start at low throttle it can damage pto
Says so in the owner's manual as well
Right video at the right time. I only have 60 hrs on my John Deere Z930M but I recently seized a blade on an exposed tree root. I smelled burning rubber before I freed up the blade by moving forward. Afterward I heard this slight rattling sound and realized I burned a flat spot in the belt. I considered purchasing an off brand cheaper belt but after careful consideration I purchased the correct deck belt from John Deere. It was expensive but after watching this video I know I made the right decision going with the OEM belt. Thank you.
good advice for a problem many people have with mower deck belts Good content Taryl
Another well timed video upload. I'm about to replace a belt on a mower I'm loaning a friend. The drive belt has a cut that keeps slipping it off a pulley.
sometimes it can be a new cheap belt that can give you the same consequences . . . a broken belt.
the best explained reason of belt breakage.
awesome video !
10,000 thumbs up !!
Thanks Taryl, had this problem myself, i appreciate your help. Rock on! 🎸🎶
Good education on belts & pulleys. Right tool for the job & maintenance go a long way.
Stay safe, Joe Z
Thanks Taryl, very informative AND entertaining to boot!
Thanks Taryl!!! Loved this midnight snack..... yummmmmy!!!😎
Tayly i got a cub cadet 1040 cant get belt right .seems it slips no speed or drive problem.anyy suggestions.
@@harryboeckler7198 Examine the deck pulleys. My nephew has a CC and it was throwing the deck belt constantly. He couldn't figure it out. I looked it over and on close inspection, you could see the tension pulleys mount, which should have been designed to have either a thicker threaded mount, or enough room for a nut under it IMO, had worn from the belt tension pulling on it. We had to replace the whole arm and that solved the problem. Part was a 'Idler Arm Bracket'. We also replaced the 'Idler pulley' because the bearing was shot, the Extension spring, belt and belt keeper rod. All those parts including shipping came to $173. It now works like new.
Thank you.
Sorry I'm in the belt section, but i m not used to posting Q's. I do like your page it's very useful, thanks Taryl
Informative and entertaining. Taryl should be on Saturday Night Live!
Also if your deck is engaged with a cable, the cables can stretch over time and also the spring at the end can wear and therefore not be tensioning the belt correctly when in the engaged position
Amine are old mechanical ones with the shaft on it good point
I learn a lot watching your channel. Thanks Man!
Good explanation on why belts may break. The tech assistance folks at Grasshopper say the blades should be engaged at 3/4 to full throttle speed. Contrary to some but it really does work.
I really enjoy your videos! Thank you Taryl & crew! Best of wishes to all. :)
One other problem I see in my shop often enough to mention is the brake shoes that stop the deck get warn enough to sit in the pulley to far and contact the belt causing the belt to break or come off when the deck it turned off,Thanks for a great video!!!
Very informative Taryl. Thanks for the info.
Interesting, thanks Taryl for the info and the dinner.
Yeah, my messed up belts were my fault when I first started doing my own maintenance and repairs. I had every problem you talked about in this video.
It seems most people do not value a sharp blade when that is where the rubber meets the road on the whole thing. Sharp blades are the number one fundamental in lawn mowing. Great job Taryl on explaining so people can understand whats going on with the mower deck.
Thank you for the information you provide. Yea have helped me tremendously.
Thanks Taryl, now I understand why my new belt for a Honda mower is not getting the same amount of drive engagement as it did when new, the old pulley needs attention!!
Another wonderful video presentation .
A good video with explanation and cautions. Thanks.
Thanks again for all of your advice I slowed down raised the deck and the belt did not come off my yard looks beautiful and there's your dinner / tonight steak and taters
Thanks for posting this very informative video. Cheers !
Replaced the deck belt on my Cub Cadet with one of those Kevlar belts in the middle of last summer. Man, it works so much better than the old rubber one did and it's still going strong.
Very helpful tip great video Taylor
Good video. You say not to go too fast or mow too low because you're feeding too much grass and you point out to make sure you have the proper clearances. One thing I saw was a bunch of grass by the pulleys and you don't say to clean that grass out of there and another thing that goes along with abuse of the belt would be having a grass build up under the deck that prevents getting rid of the grass quickly and causing the slipping of the belt. Also found a portion of a tarp wrapped around one the the blades on a S160 John Deere.
Good stuff. Thanks for the info.
Great advise and thanks for sharing it!
Thanks T .Always good info here .
Taryl, at work the belts we used are Dayco blue ribbon. The best belts ever made period. I do not know if that has changed but I stand by my statement. Nice video too.
As usual a great Hamms beer inspired video:) Taryl you rock!
Send that man a case !
Great video, Taryl Dactyl!!
I didn't even think about different V designs. Size make sense... though didn't thinking about differences in thickness and V shape. Thanks for sharing!
Now for what makes the squeaky belts maybe?
Man I love your videos! Very knowledgeable and hilarious too!!👌
Great tips bud. I find hitting stumps works great at breaking belts too 😀
Belts even snap on large agricultural equipment like combine harvesters and field mowers due to the same issues and those belts and pulleys aren't cheap to buy or repair.
thanks for the help, it worked for me, I bet with all that knowledge you could make adjustable brake pads for the blade pulls, so you can just loosen & slide pad up or down, instead of having 2 wear spots you get 2-3 more uses
Had to learn the hard way as many others on belts. Most mowers must have an original equipment belt or you will positvely have nothing but problems. On another note! I never gave pulley wear much thought! Thanks on that!
Yes I have went through all the belt troubles mentioned my old mower that I got for free basically learned all the things that Taryl teaches here the hard way lol
Also if your pulleys are not ridiculously worn-down you can clean them up with some sandpaper and that will help.
I did the angry belt dance at the end myself a time or two.
angry belt dance, yes, I've taught that one at my shop.
Thanks for the information on the Belt angle never thought about that, but more importantly where the hell do get the Hamm's t-shirt?
Yeah great teacher.. we learn so well when it's fun..
Grass packs around pulleys & deck EVERY TIME I mow. Have a 48 inch air blow gun from Harbor Freight and use shop air to blow deck clean before putting garden tractor up. If used water to spray off, would have to wait to dry & might cause rust our damage grease seals.
Great info Taryl! Thanks👍
Nice video. Forgot to mention frozen bearings on blade spindles will break belts too.
Love that shirt.
Love that necklace.
Love this channel.
As a old wise man said.....lawnmower is not a Bush hog.
That’s why you should cut your grass weekly I mean that’s how I do it and it looks nicer when your done if you cut 16 inches of grass it’s all dead because it didn’t get any grass plus it bogs down there mower if I want to cut that I use an old self propelled garden way sickle mower works great
Well, if you go real slow, and have the deck set high, they'll bush hog pretty well. Depends on the HP too. I end up bush hogging sometimes when my horse pasture gets out of hand, when I've been busy on other projects and neglected mowing. I've cut waist and even shoulder high weeds and grass with a LT1000 with a 17 hp Intec, and it never bogged down, I just had to go real slow. Main problem bush hogging with a grass mower is the deck. It's too enclosed. Bush hog and brush cutters have the front of the deck open, so the blades can hit the weeds without being bent over by the front edge of the deck. I recently purchased a junk LT1000 with a deck for $50, and am planning on cutting the front and sides of the deck away, and installing it on my good LT1000 and see how that works cutting weeds and brush. The worst problem really with all of these riding mowers is you can't raise the deck high enough for the best brush hogging. I'd really like to be able to have the deck at least 6 inches off the ground. But all these mowers are designed for mowing golf courses it seems.
@@hunter7476 I have one of those Garden Way sickle mowers. It's sitting in my barn unused for many years now. I got it used, in good working order, with two blade heads. The thing breaks teeth way too often, and they're a pain to replace. Plus, you can't use the cheap normal teeth for farm sickle bar mowers that you can get at TS. You have to use TB's special teeth that cost ten times as much. Eventually both cutter bars, the steel strip that the cutter teeth are riveted to, snapped in the middle. That little piece of steel costs $150 to replace. They get you coming and going. Someone needs to devise a way to make a better cutter bar for this little mower that can use regular farm teeth IMO. Till then, brush mowers that simply use a normal lawn mower blade are far superior because they are cheap, way more durable, and easy to sharpen or replace if needed.
Or the shuttle
I was able to mow 2 foot tall grass with a 1987 Craftsman lawnrider with a 12hp OHV engine in it. 36" deck on it.
what I did to do that is had the deck set to the highest setting and went in first gear, full throttle. it cut that grass like BUTTER when I did that! never bogged down once. (the highest deck setting is I think 6.5 inches off the ground if I'm not mistaken) full-on BEAST of a mower
just a little tip for y'all: if you encounter tall grass while on just a basic riding lawnmower, mow it in first gear with the deck at max height
*THERE'S YOUR DINNER!*
Very nice awesome! I love this keep doing it. Thank you.
Wow such great advice, Taryl I want to adopt you as my uncle or meet you and become great friends.
Thank you for your videos and expert content.
Good vid. Very good props. Great upload 🤔 lots of info
Aircraft Mechanic> Taryl, I have had Aircraft Mechanics not understand the V belt problem. Good job.
Top tips from a top man well done
Have a great day everyone
Used your Taryl Putty today. Looks like it's gonna work!
2:30 if the pulleys are really worn they will bite into belts and won’t want to release them. Learned that from an hvac guy that works on electric motors and fans. Wears the out even more and extra load.
Don't think i would agree with that description. Worn pulleys would lead to the exact opposite of biting. Slippage, therefore heat, and glazing of the belt would be the result. Worn bad enough, the side of the belt isn't gripping the pulley at all, and could or more likely be riding on the inner circumference of the pulley.
I'm surprised Ya' didn't mention engaging the cutter only at engine idle...
I had to scold my neighbor (a dear friend) for smokin' deck belts engaging at full throttle.
I love your work, guys; Learn a lot, always get some giggles.
That's a good video Taryl! Now I want to know how to measure a belt size so when I work on old rusty junk I know what to get when I can't find a belt part number
Get you a belt measuring tool from McMaster Carr 😉
And theres your dinner Dude i love your videos you da man ive learned alot from you keep on keeping on .
Regular fan belt will work fine on a modern belt drive hydrostatic mower, but may wear faster on manual transmissions because of the clutch. Also usable for starter-generator drive belts.
Taryl, I have an old Merry Tiller (1977 I think, from the date code on the engine) with the 5hp Briggs that I took apart to fix a fuel leak on top of the fuel tank. I believe I put the governor linkage back wrong because now it runs fine and throttles up fine until you load it. It has no power under load. Is there a diagram somewhere that you know of that shows the linkages? Or at least a good description. I really am grateful that you do these videos. You don't owe this to anyone, yet you do it. Thank you. I hope you aren't too busy to read my question, I bet hundreds or maybe thousands of people try to contact you.
Love the t shirt 👕 also good info as always 👍
Thank you!
Great video Taryl. But I have a question. Spindles with zerk fittings versus manufacturer spindles that don't. Which ones are better?
Better with greaseable bearings, but only if you grease them
Hey Taryl, how often do you come across a Sachs or Rotax rotary engine
dear Taryl greatings from France !! i like your video !so interresting and funny i learn more whit you as many other guys doing video!! in france we said ( gros bisous de France! ) big kiss from France i hope more video soon!
Taryl upload
THIS LATE
Must have been up late with that hamms
Must own some of Hamms stock.
Another great video sir!
Hey Taryl,
I have a around a 2003 18 simp regent 38 deck. I bought it for $100 the guy said it just needs a drive belt. Kohler engine runs good. The problem is I don't know what all I have to do to change this belt. It looks complicated n id like to be sure its not the trans locked that caused the belt to snap. The belt is shredded. The guy started to work on by removing a bolt n I have no idea where thats supposed to go. Before I lift this thing with my crane id like to know where to start. I also saw on one of your vids you talked about the parking brake can cause the belt to brake.
Just was hoping you had 1 of these hanging around that you can do a video on. Thanks
Oh n your videos are great. You guys are hilarious. You make it fun to work on the junk we have to deal with these days.
Need a good small motor repair thanks for info, and good show
Good video Taryl
Yup, there's no such thing as a bad mower, just BAD OWNERS! Great vids TD.
WOW. Your teeth look straighter today. Glad to see your back.
good video....gotta get to my mowers in winter before i need em
Good info Taryl.
Thanks man this was a great help
Good tips. I have a 30 year old wheel horse that doesn't drive right away in 3rd gear, it screeches and then goes. I replaced the belt some years ago and used belt dressing but it still slips, I thought the belt was too big. But maybe my pulleys are worn out.
Hi I love your videos as you can probably see by my profile picture your videos make my day thanks for all the dinner
Good and correct information. Some belts are over $100 and while they do last a long time they eventually wear out and when they do it is time to look at and replace the pulley and idlers. Everyone wants to replace just the belt and then complains that it didn't last as long as the original. Duh. OEM belts usually cost more but you are already at the dealer buying new pulleys and an idler or two Right?
Great information
Taryl is making videos to this day and they are always ground-breaking.
Hey Taryl a kevlar rapped belt is designed for abrupt speed changes like the mower deck clutch engaging or like a clutch an mechanical engagement belt. Slips a bit then drives unlike a rubber belt that will abruptly engage but has no slip and tears itself up in summer heat. Case in point a snow blower has rubber belts due to temperature and moisture these resist slippage and grab under these conditions.A kelvar belt would slip and keep slipping no grippage with the moisture soaking the kevlar.
I love the sound affects :)
I love a late night snack 😅. Thank you sir 😊
Hey Taryl, can you tell me where you get the stupid double ground wire with diodes for a Briggs and Scrappen 16 horse Vanguard?
Thank you brother.
Thankyou that was a delicious midnight snack
