Continually having the clutch cut out and quit mowing. Have to stop and move deck up and down to get sensor back in line where clutch will engage and mow. There is not enough tension to hold sensor down where it will not stop the clutch. Undercarriage parts continually breaking as well as pillow blocks giving problems. All of this is on a 722D with front deck. It is a.long way off to a Grasshopper dealer and the repair wait times are not good at all. I am buying a backup mower where I don't have to go through the agony when in shop. For what a replacement for a 722D would cost I can buy several good zero turns in its place. User's recommendation: Look around.
