Hydrastatic transmission won,t go in reverse Original Message Jun 2, 2005 4:34 pm
Folks I am in need of help in the form of information---I have a Stanley(Murray) Model 525607x692B ---52 inch rider. While mowing today it hung in the forward drive. Cut two acres of grass just going forward. Can,t see anything wrong with the linkage but my foot operated lever will not go to neutral or reverse. Called Engine Southwest, the parts source in this area and they tell me the hydrastat comes in 2 pieces---the differential ($215.00) and the Pump-($310.00) It could hardly be the pump for it runs too well in forward. I suspect it to be the differential My question---can anyone tell me if I could install my present pump on the new differential or does it take special know how? Would appreciate any help----Your friend--Will

Chris--Man I appreciate someone like you-----I do have to watch myself very carfully but I have a Electric hoist in my shop and I am going to take the rear wheels off (I will get my son to come do the heavy work). with them off I can raise it up where I can see things easily. I can then do as you said, disconnect the linkage from my foot petal control and can see what moves, etc. It acts like something is jammed and not releasing. When running the mower ,the only way I can slow it down is with my foot clutch. When I clutch it I notice my foot pedal will release nearly to the neutral position. Hopefully , sometimes tomorrow I can get my son to come help and can find out something. The parts man at the parts distributor stated the pump is mounted separately to the differential. I, like you, still more or less think it is linkage. ---your friend-Will

Will - it sounds like the linkage could be jammed up, but on some hydro units there are opposing springs to return the foot pedal to neutral - maybe one popped off or broke? When you say the pedal returns to neutral when using the clutch, I possibly suspect that a spring has "sprung". If so, this might be a very simple repair. Even though you have the electric hoist, definitely place something under the tractor to hold it up "just in case", like a pair of cinder blocks. And definitely take it easy - we want ya around!! Good luck & let us know how you make out...
A note to ALL - Always have a backup method of supporting ANY vehicle, whether it be a small lawn tractor or a truck!

Marty---Thanks for the info on the linkage. I do suspect it has to do with that. Also, thanks for the concern---I do get reckless at times and I will use a extra safety device.---Will

FOLKS---Just wanted to tell you I got my hydrastat fixed this morning with the help of my wife to do the heavy work. . I hoisted the rear end of the mower, removed the rear wheels so I could see the unit well. Could not believe what I found---the arm that the rod from my foot pedal connects to was the problem. The bolt that secures it to the shaft that goes into the transmission was about to fall off. The 1/4 inch bolt had loosened enough that it had jumped the tract that keeps it in between the return spring. One of you told me to look for such so I wanted to tell all I appreciate and it took my wife and I about 30 minutes to repair it. Thank you all and may the God of the universe watch over you, your family, now and always.---Will
