TC33d Hydro Issues

[SUPERCRUISER]

New to the group. I have searched through as many Hydro posts as I can find and couldn稚 find one describing my issue. I have a TC33d that has 650 hours on it. I used it all day clearing brush. Went out the next day and it wouldn稚 move. PTO, 3 point, and loader worked fine. I changed both Hydro filters and checked the fluid. Now it moves but only if I push the pedal 50% or less. If I push it any more the tractor stops. The engine rpms are rock steady throughout this. I kept using it in its current state due to necessity. At 1st in tall grass etc the PTO would slow down and the tractor would move slowly. After about 30 mins it was working almost normally. If I stopped and idled down for any reason it would revert to not working again. Then after 20-30 mins under power it would be almost normal again. My wife thinks maybe I should just not quit working. Any better ideas?

Sounds like you are either low on hydraulic fluid or the pressure relief on transmission is opening. pm me your email address and I will send you info that explains how the transmission works and relieves.

I checked the fluid and it is correct according to the dipstick. I can add more to see if it helps. I just didn't know if that would cause more harm. Thanks for the reply. I'll send my email.
