I have a 424 gas burner I"m having hydraulic issues with. When I first start bushoging everything works fine. After about 15-20 minutes of heavy cutting the bushog starts bouncing a little. Not to long after that the tractor lifts the bushog completely up(without moving the raise/lower lever). The tractor holds the bushog up until I bring the rpm's down to idle. When I return to mowing rpm's, the tractor lifts the bushog back up. Once I let the tractor cool down, it works fine until it gets hot again.
Anyone know whats happening?
ps...I replaced the orings in the isolator valve and the speed control valve. Stopped the leaking but didn"t fix the above problem.
Thanks in advance,
Ray
