Re broken handles. One of the hazards of the self propelled DAMS, Concepts, and Powerdrives is the sliding powergrip handle. You have to be very wary about not lifting these machines up by the handgrip otherwise you can either damage or disconnect the control rod wire inside the grip. I know, SIL when she lived here was constantly doing it on mine when she'd car the machine up the stairs no matter how many times I told her to use the hand hold.
