    I have a question about my 1997 walker. I recently mowed a large hill and about 80% through it would no long climb steep. The hydros are making whining sounds only foward. When in reverse it still had plenty of power to climb. It seemed to get worse. I checked the fluid in the hydros and it was perfectly clean with no smell to it. I am assuming (hoping) That I stretched the hydro drive belts to the point that they slip? Or would this not cause the hydros to whine? I assumed this because I can't imagine blowing 2 hydros at the same time and the fluid was clean? :(

    Start with the belt.
    I assume your hopper was part full?
    It still goes on the flats?

    Thats what I was planning but, it still goes and mows, on flats it doesnt whine only on hills which it still climbs just not quite as good as it was.

    ksland,

    Your problem is due to dust and grit getting imbedded into the belt and the belt looses it grip on the pully. Turn a section over and look into the grooves and you will see shinny spots of grit. The PTO belt for the blades will get embedded also. The drier the mowing conditions the more often you need to change your belts.

    someone told me the pulleys get worn and it will cause the belts to act funny. not sure about it though. gotta replace mine soon. checked spring tension?

    if the belts clean, change the spring on your idler, especially if you have a speed-up kit.

    a lot of theses were installed without the right spring to compensate for pulley size.

    Just what Dave said. I had the same problem and found out that the upgrade spring wasn't in my kit. After installing the spring, it was business as usual.

    which spring is the one to pay attention to? the more forward one at the front of the tractor? i don't have the speed up kit but question the tension on my springs.

    found it, right after i posted actually. the spring has a gap in it between the coils about 7 or 8 turns from the top. checked the belt and it's got minor cracking but no glazing or dirt.
