I have a Craftsman 19hp Twin Turbo lawn tractor with hydrostatic transmission. Recently, the tractor does not go up hills or at any incline like it used to. When the tractor first starts, it seems to be OK. Then, as it heats up, a high pitched whine emanates from the tractor when I attempt to go uphill. I changed the front motion drive belt, but this had no effect. Sears will charge me $96 just to look at it, and if it is the transaxle, it would probably be better if I bought a new tractor?? Looking for advice...it is a sealed unit, but is it missing some fluid? Thanks for any help.

Thank you for the reply and schematic site.  I just looked at the transmission and it says a 310-0650.  Is that the same as the 319-0650?  ...or will it work the same?

Sorry, no idea. You sure it's a 0 and not a 9?

Hello, I have a 19hp craftsman, I changed out the 16.5hp for a 19.5. After i did that it was hard to shift the gears. its like a standard car with the clutch starting to go, it seems like its locked up. any suggestions to my problem?

thanks
