No matter what, I cannot seem to stop "mashing" the ground beneath me when I turn on the Z. I do a 3, 4, and 5 point turn and it still happens. Just today, 1/3 of the way thru a lawn, I gave up and got the walkbehind. I was "mashing" the ground just driving straight???? I have been in the game for quite a bit so I know its not my driving..... Must be the time of year I guess...but EVERY lawn???
