312-8 does a wheelie everytime I let out the clutch

[Alrashid2 165]

Thanks for sharing that Ed. Thats curious... I don't have video but it looks like mine doesn't grab and spin the pulleys until the travel is almost complete and the pedal is nearly released.

 

Yours looks to grab almost as soon as it lets go of that stopping point...

Al, see the edit about the dampening cylinder.

Mine seems to be missing one of those angled metal pieces when compared to yours? Mine also seems to rest much farther back in tracely

Apologies if someone already mentioned this, but the belt should be fabric covered, not plain rubber. The fabric lengthens the service life AND helps with smoother starts by changing the friction dynamic between the belt and the pulley sheave. Also, as a belt nears end-of-life, the SIDES wear to allow it to go deeper into the pulley sheave (belts DO NOT STRETCH). This can make them grab too.

The belt does move as soon as the belt brake is released, but that is because the transmission is not in gear therefore there is no resistance on the tranny input pulley. When it is in gear, the belt does not move until the idler pulley tightens the belt.

I'm very perplexed. Just can't seem to figure out what is causing this. I wonder if a new belt would help but I'd buying aftermarket.

Yes, yours does not have the clutch damper like mine and your idler pulley is further back when engaged.   Some gear drives also used a gas cylinder instead of a spring to provide the tension on the belt.  These clutch cylinders I am sure were an attempt by Wheel Horse to ease this sudden belt engagement problem.

 

My only suggestion would be to buy several different length (+ and - one inch) new belts from TSC and test them.  If you keep the belts clean, you can return the unused belts for a full refund.

Wow! I've never had an old post of mine referenced before!

 

I just wish it wasn't the one where I tried to run over my garage 

 

I did get everything sorted out, thanks to the advice on the other thread and some of the same advice on this thread.

 

A new belt went a long way (I'm using one with fabric sides from TSC) as well as a good cleaning of the drive pulley on the engine. That is the pulley that you want to slip.

 

When you have the clutch in, the belt is loose and is actually stopped by the belt guard up near the engine. This is why you're gonna have a hard time switching gears with no belt cover. As you slowly let off the clutch, you're tightening the belt around the engine pulley and you want it to slip a good amount. This lets both the tractor get up to speed, as well as doesn't shock your engine. I saw in your original pics your pulley was a little rusted and your belt was shiny. Shiny belts grip faster/harder, which is great in some applications, but not for what we need.

Thanks for chiming in. I was hoping you would.  

 

No worries on the Horse vs Garage issue. Some are just more ambitious than others.  

 

 

 

 

And for the record.... my 9174 C160-8 Cinnamon Horse tried it too. House attempt. Tossed me right OFF.   

I was fine. 

Shocked. Impressed. But fine.

Not a fix but, why not add some weight up front? I bet it helps...Weight is your friend on a ...

 It's tough quoting @SylvanLakeWH but he 's spot on with the front weight.

The simplest and least expensive is to fill your front tires with RV Antifreeze or beet Juice.

Since your not planning on using a mower deck, you can make weight mounting brackets that use the front hitch.

Also like Sylvan and Ed kennel,  I find weight machine's at the curb or Dumb Bells or steel weights 

 

P.S. Keep working through things you'll have that Horse tamed.

Gonna need video on that... rules is rules...

You might try taking the sheen off your existing belt by buffing /sanding/scratching the sides with some scotch Brite, 180 or 220 sand paper to see if it helps. 

If it does, then a  new belt sounds like a good idea.

I kid you not....

Trina was getting video of the day I was doing some testing just as we were finishing up the restoration. 

I'm toolin' around the driveway..... all is well.  

 

She goes inside and WHAMMO!! 

 

The tractor's fender pan latch was loose and I KNEW IT. 

I was ready.  

But it still foofed  me right off the back when the seat flipped up.  

 

 

WWEEEEEEEEEEE

Get Trina and the video camera back out there and do it again.          You know if there are no pictures,  it didn't happen.          

          is foofed one of those words that only appears in a Maine dictionary?

As a native Mainer, An appropriate Maine substitute could be “stove up”or something less NSFW “ ****** up” 😁

@Alrashid2 I’d run it and get used to it. You’ll eventually find the sweet spot where it just goes. I’ve had mine three years and it still jumps every so often. But, you will get it. The plow does help with weight on the nose and it isn’t so abrupt. Wheelhorse did sell a weight kit for the front that I have on my 312. You probably could make it with some Quick Crete, some long heavy duty bolts to mount the blocks. A 1/4 thick 1 inch flat bar bent into a C to fit the front of the frame. There are some existing mounting holes for 5/16 or bigger bolts and a horizontal quick release bar there.

Put these weights on my 856 after she flipped over and put me in the hospital.

I had this problem on my 312-8.  New belt and adjusting the clutch damper solved the problem.  Sorry I don't have a pic of the clutch damper.

[MainelyWheelhorse 433]

 

@Alrashid2 A pic of the front weight. The 312 is the tractor on the right. I put the weight on when I had the issue of wheelies like you are having. I think the OP bought it for counterweight as he was 300+ at the time.

Seems to me those are a rare and somewhat valuable piece.

My dad has one of those on his 312-8.  Came with the tractor to counter balance the Trac Vac unit.

[MainelyWheelhorse 433]

@Bill D My 312 originally had a bagger that has been lost to time. I’m thinking that’s what the front weights were for, as well. That and the original owner was 300+lbs.

[CCW 1,293]

At a construction site once and found three 10" cutoffs from concrete filled post.  Asked if I could have them and then welded them onto an old mule drive after removing the pulleys.  They added 75 pounds to the front end which helped when I needed it to learn how to use the finicky clutch on my 312-8.  Price - the cost of electricity to do the welding.  Somewhere on this site is a photo of them, but have not found it yet.
