JD L110 Possible Hydrostat Issues?

    I have a JD L110 "automatic" with a 17.5hp Kohler engine, 42" deck and "automatic" trans with foot controls. Has the original turf-type tires as well.

    The machine has 480 hrs on it, I think it's a 2003/4 model. Starts and runs fine.

    My yard here in MT is fairly uneven and has some gentle sloping hills.

    This mower cannot even climb the slightest hills--usually ends up with one tire spinning. If I shift my weight, that tire stops and the other one ends up spinning! It is also very slow in reverse, even on flat ground and has even more difficulty backing up hills--usually can't be accomplished.

    Is this just the nature of a low-end JD mower, or is there something I should adjust or look for in the hydrostat mechanism. I can work on engines, but know nothing about hydrostat transmissions.

    Any help much appreciated.

    It's an open differential so the wheel with the least traction will get the power applied to it.

    I'm not sure if your transaxle on that machine is servicable or not, but the lower end L series have about a 500 hour life span on the hydro system.

    Take it to the deere dealer, have them service it or at least tell you what up with it. If it's servicable and in working order, try adding ballast to your tires for improved traction.

    Another thing to check could be tire pressure.
    Yours should be I believe 10 psi on the rear.
    If you add to much air the tire will have less traction.

    Spec on the speed is
    Travel Speed - Forward 0 - 9.2 km/h (0 - 5.7 mph)

    Travel Speed - Reverse 0 - 5.5 km/h (0 - 3.4 mph)

    I am sure that is on flat terrain.

    Ok forgot about you probably have two belts.
    One is for the transmission.
    So if you don't get the speeds as listed then the belt could be worn out or if you have oil leaking on it, it could be slipping.

    Thanks guys. Just got back from vacation and it's actually gotten worse!
    It will barely climb even the slightest slope, and just barely creeps in reverse.
    The belt looks OK, maybe I'll replace it but I think it may have bigger problems than worn belts.
    Is there a way to rebuild these things??
    We just don't have the cash right now to buy or trade mowers...:cry:

    rebuild kit is about 500... new trans is about 600.

    The answer was stated. ^^^^ Just buy the new transaxle for $600 and be done with it for another 500 hours.
