My problem with my Toro MX4250 zero turn is falling asleep at the wheel - or, at the levers. I think it is being so close to the ground, with a green field of colour sweeping by constantly. I have mini-dozes and jolt awake a couple of metres off line. Hope I don't have one when there's a tree there, some day. When it gets really bad, I have to stop and go and some whippersnippering or whatever; then I don't feel drowsy at all. Anyone else have this problem?
