What is this switch?? Have to press to back-up while mower is running one? I have that on my Deere. You don't have to Hold it while backing. Once you touch, long as you have pedal down (on mine) and don't let up or stop, it stays running fine. If you slow and let-up on drive movement, it will quit, so have to learn to keep your Foot into it, as they say. IF you have a lever, might be same, not sure. ON the new stuff there is a control box now that needs input from ALL the safety switches to be in right positions to make it run/drive right. If ONE of those is not correct, there is no signal to box and it does not allow movement. The old days of just putting a cross wire in a plug or by-passing is not going to work anymore. You'll just have to get used to the procedure, much like Car Seatbelts that everyone tried to by-pass in past, now they are needed and you get used to using. Heck, ON seatbelts, I find myself even putting on just to back-up in drive or something, it becomes automatic. Also, shops can not by laws change/alter the switches to our liking anymore either. You know even on here, they don't wish to have subjects about doing changes to safety systems. The Operator is what needs changing of habits!!
