I have a two-year old 18/44 FasTrak. My problem is that both of the lugs that allow the engine access panel and seat assembly to swivel up have cracked and seperated. The only thing now holding the seat on the mower is the two rear bolts. It appears that this is a design flaw. Not enough material was allowed for the stress and vibration at these swivel points. Has anyone else seen this on their FastTraks. Inspect these swivel points for cracks and seperation. Is this covered in the frame warranty?
