A short time ago i got word about a mishap of sorts. It involved a gravely z. Brand new it was. The unfortunate man backed it off the trailer and engaged the pto. CHABANGGG... BABOOOM... I dont know all the gory detailes yet or even the exact model, but i will soon. I think i remember something about the pto clutch blowing and something else going clankidy clank. I am not bashing gravely, infact i think they build as good a machine as anybody. I'm sure any brand name has had their share of problems from time to time. Just thought i would share what i have heard.
