I have a Scott 50567X8 20 HP tractor that was having problems with the 205-023B transaxle. Was cutting some thick grass, when tractor quit moving. I had been having problems with was not being able to go very fast up hill in forward and in reverse. Had just replaced drive belt, so I knew it was okay. After extensive examination, I determined problem was in the transaxle. Removed the transaxle and took it apart and found a roll pin broken. Replaced roll pin, cleaned inside of transaxle. Found no other problems. All gears, shafts, seals, bellows, motor and oil pump, visually looked good. Reassembled. Refilled with Synthetic oil 15W50 motor oil in the Hydro section (about 1.5 qts) and 85W140 Synthetic blend gear oil the the Differential section (8 oz). Tested with back end on jacks. Seemed great, forwards and reverse.
Now for the ground test. Great on level ground, but still low power going up hill forwards and in reverse. After reading others with the same problem I decided to purchase the 799031 kit from Sears direct for $ 543.00. The kit includes the new LTH transaxle, a new longer drive belt, a couple brackets, pulleys, clutch spring, and necessary hardware, and installation instructions. Oil already in transaxle. Installed, tested with back end on stands, worked real good.
Now for the ground test with the new transaxle. Real good on level ground. Fast forward and reverse. Fast in reverse up a hill with about a 22 degree slope, but in forwards up the hill I'm getting something grabbing and releasing. grabbing and releasing in the rear. Can't figure what it is. Belt is not slipping. Rechecked everything per installation instructions, but everything appears to be okay. The tricky item in the installation was the Disconnect Linkage Rod under the seat that engages the transaxle for drive and disengages for manual pushing. It had to be bent to make it work. I had a rough time with that. At one point, I removed the rod, because in drive mode, the disconnect lever on the transaxle is relaxed, not under tension. That did not help.
I have said a lot here, but I hope someone out there has installed one of these 799031 kits and maybe had the same problem and can help me. I am sure it is something simple, but I haven't been able to figure what it is.
