Need some thoughts. Tractor runs good for 3 yrs. Now it screams in reverse. If slow it's less and increases as you want to reverse faster.. this problem came on pretty fast. If you want to back up hill it will just scream. It is hydrostatic. Ed Will Oliver BC
 
Hi, I don't know if it is a Tuff Torq transmission, I
will look in my manual to see if it says there. I can't
crawl under as I'm bunged up right now. Thanks for
the comments. Ed Will Oliver BC
 

I would think it is a Tuff Torq, K46 or similar, they are common but they dont last forever, especially if worked hard, and they arent really servicable. If that is what you have its likely not worth repairing.
 
If I remember correctly look on the rear of the tranmission body over to the right. There is a little metal tag or stamped into the case.

One little tip. Had something like that happen one time with a Cub Cadet. Remove the right rear wheel, take the brake all apart and clean everything. A tiny dab of grease on the moving parts. In reverse a messed up brake will lock and really screeeeeem. Check it out.
 
3 things to check:

1. That clutch pedal has a metal stop that goes down against the steering gear plate when the clutch pedal is released. check to see if there is any grass debris under that stop. its near the left side frame rail. If the clutch doesn't fully engage the belt can slip.

2. It is not uncommon for the front transmission mount bolts to strip out of the transmission. Then the transmission can twist and the belt can slip because the pulley is not rigidly in place. (probably will slip more in reverse as the transmission has a tendancy to twist forward.)

3. Do you see any oil leaks anywhere? Like up near the pulley or at the axles? If the oil level gets low it will gat noisy right before it gets to the point where it won't work at all.
