Well it one here that the customer have broken three brake cable as they were so tight you play a tune on them or the PTO clutch that the deck braking system falls off. That particular clutch BB stop using.
Or a Gravely where to deck baffles mounting points breaks off due all the flexing. Customer done had them welded but whoever did it did poor job and they also didn't re-enforced those areas. Not my place to warranty someone else workmanship.
Or the customer that brought a JD X350 that keeps throwing the deck belt and JD hasn't figure what causing yet. That customer said I would be getting it when the warranty is up.
