2009 husqvarna riding mower yth20k46.... problem.

[bernieb]

This mower has 220 hours on it, and has been doing great, but lately after an hours use it stops going forward and sounds like grinding gears, but after mower rest for a couple of hours it starts up as usual and goes on cutting just great. any ideas on what to suspect?

Does it have a hydraulic oil filter? If so, when did you last change "it" and the hydro oil? This oil breaks down after time.
