Other things to check or watch out for... It should have a suspension seat but some get stuck in the down position. Try the PTO cable a few times, mine does not always turn off. There was a fix for that but not all of them were fixed... mine did not. The hydraulic fluid sight glass on the "driver's" side of the middle hump has cracked / leaked on a few. I've read something about the hydraulic return hose (right side by gas pedal), early models have leaked but not sure when that was changed out. Another thing to check out is the front steering tie rods and make sure they are not bent (they are vulnerable).
