My lawnmower, a 60 inch cut zero turn mower wont mow, mater-of-fact it wont move either. I was mowing and it just died, It will start run but when i try to engage the deck it will die or when i take the brake off to drive it it will die. I think it has something to do with the safety switches but they seem to be OK as I checked them with a ohm meter and looks good as far as i can tell. It has one switch under the seat and lift the seat and there is one that the brake and leavers operate. I have tried disconnecting the seat and it doesn't change anything. HELP ME!!!!
