Don't expect the rubber hold-down straps to survive more than a year, if that long. The rubber will break down just like longer hold-down straps that you may purchase at a hardware store. Unfortunately, these are a custom size and not locally available. KEEP SPARES ON HAND.
The attachment bolt/sleeve for the rear hold-down strap to hook on will not hold up either. Vibration and the sideways heavy pulling by the strap on the unsupported end of the long bolt will break it off in time. When this happens, count on loosing bolt, sleeve, washers, & lock nut. KEEP SPARES ON HAND.
The front attachment strap is supposed to hook through an existing hole in the deck. The problem is that threading this hole with the spring hook on the strap is nearly impossible as the weldment bracket for the right-front deck-wheel gets in the way.
