    Toro 255 52" Z-Master seems to be slowing down.

    Hydro fluid level is good.

    No leaks.

    Only 115 hours on machine.

    Am I just imagining this?

    Any ideas?

    Is this on grass? Is this with the blades on or off.

    I am not familiar with your mower, but the 1st thing I would check is what your engine is at when at full rpm (it should be around 3500, maybe a little more).

    I would also inspect anything that has to do with getting your engine to rev fully.

    Next I would look at adjustments you can make in using your sticks to turn, go forward and back, tracking, etc..

    Just some thoughts Envy...hope you find the problem.

    Scott, its probably that the belt that runs to the hydro pumps from the engine has stretched. It happens on my wbs so i assume it could happen on your z

    has the hydro filter ever been changed? should have been changed out at 25 hours the first time. I disagree with the belt stretching - todays belts have woven kevlar in them it's alomost impossible for them to stretch

    i agree with redbull. if both pumps are slowing but your engine rpm is still at 3600, there almost undoubtedly has to be a restriction in the filter.

    1st things 1st.

    Is the engine speed slowing down or the ground speed?

    If the engine revs fine then I agree that it may be the belts.

    My Walk behind too has that happen from time to time (simple adjustment thouth).
