My neighbor came over today with bad news. A guy he knows just got killed on his ZTR. He didn't have all the details yet, but the guy was mowing a site he'd been cutting for over 6 years with the same kind of ZTR, and didn't live to finish this time. Apparently the ZTR lost traction on a slope and went out of control. At this point, I don't know if it was a crash death or a rollover death. But it just goes to show how untrustworthy these things are. Even if you have done something safely a couple of hundred times doesn't mean you will next time. My guess is that the drought conditions were the variable... hard ground, dry slick grass.
