Had mine over five years, 534 hours. Only problems is the idler pulley, replaced once, steering spindles replaced, steering rack and pinion gear replaced and three belts. Steering spindles failed due to lack of maintenence on my part. Belt problems due to burr on the idler pulley. After filing the burr off, belt wear is normal. Steering rack and pinion gear are worn out again. May be due to bent steering shaft as I have been kind of rough with it due to rough terrain in my yard.
