Failed Farm Tractor Seat

Metallurgical failure analysis was requested on a failed seat on a farm tractor. Visual examination revealed that some of the bolts attaching the seat to the tractor failed. Further investigation proved that not all bolts had been in place when the seat failed, and the bolts which were in place had not been adequately tightened. The cause of the failure was found to be inadequate maintenance on the part of the owner or operator.
