Im still not sure the issue John, but you may have too big a belt, or really bad luck lol.

In your video I believe you say it has had a different motor put in it. I was thinking that maybe some of the belt guides that help keep the belt in place may be adjusted wrong or missing. When you clutch these tractors the belt guides keep the slack belt from falling off of the pullies. If the belt falls off when you push in the clutch you don't know it untill you let the clutch out and it doesn't move. Just my 2 cents worth, good luck in your trouble shooting.

Which one does it roll off if not under load? I'm wondering a few things. Assuming the belt is the right one, If it's always the tranny end, I'm wondering if the tranny twisted or input shaft bushings is worn? If it's the engine end, did the frame flex and allow the engine to move?

Last fall, I was playing with a snowblower and having trouble. The engine pulley had moved slightly, causing the belt to be offset... Even after I fixed that, it still kept shedding the belt. Seems the offset broke a cord and made the belt tend towards turning outwards or inwards on the pulley. I still have the belt as a reminder to stop assuming things :D

Hope it presents itself easier for you... And don't forget lightbulbs when you go shopping.

I had that problem with my lt4000. The belt was to big and the rear pully was worn out.

99% of the time it rolls off the input pulley on the tranny. Every now and then its both pulleys. I checked the rearmost pulley and its not bent and has no side to side play so I assume the bushing is fine. The belt never comes off with the clutch in. Usually it will lurch forward a little bit and the belt will roll off.

Thought three & four.
Grab ahold of the engine pulley and lift up & down.

See if the belt guides near the engine pulley can be adjusted in some.

well guys I think I got it fixed. I picked the back end of it right straight up and down and was going to try welding in 2 more guides along the back when I had the idea if making a guide that runs along the side of the pulley from one peg to the other. I found some rod in the scrap, bent it up and tacked it on. Now I can dump the clutch in 4th gear running wide open and she dont come off. Havent tried working ground yet, but I think my problem might be solved

Great news, so it was the belt guides not doing their job?

Ain't it great to walk over to the scrap pile and come back with a solution? LOL
