And that is how so many riders get bad mouthed by their owners. They hit such items ten minutes after they get it home new and then forget about it. A couple months later the unit starts tossing belts every ten minutes and they take it in for warranty work and get presented a bill for the work. They are upset. If it were me I would take a good look at my belts, idler pulleys, springs, mounts, blades, spindles, deck. If everything seemed to be right I would then begin using it again. Hitting things happen. So does damage.
