hydrostatic

So over the years my jd 855 pedal has become harder to press. Has anyone else experienced this?
it's become so bad I have to stomp on it to get it to move.

Re: hydrostatic

I would be inspecting the linkage for obstructions or bent parts and I've have a can of spray lubricant in my hand to squirt every place that should move.

Re: hydrostatic

Agreed. Lube linkage pivot points. Could also be a bad bushing somewhere. Hopefully not something inside the hydro itself.

Re: hydrostatic

I think it may be inside

Re: hydrostatic

There isn't much inside that can cause your problem, but there is a bunch of stuff on the outside.

Note that I'm not discounting the possibility that the problem is inside, but the odds favour the pedal to transmission linkages as the source. Only after the linkages have been proven to operate freely and correctly do you consider opening a hydro.

Re: hydrostatic

Maybe disconnect the linkage right at the hydro? Might tell you where the drag is. However, if there’s a bad bushing in the linkage, the resistance from actuating the hydro might be just enough resistance to magnify a bind in the linkage (bushing).

Is it just as hard to move the pedal with and without engine running?
