I turned off my BX2200 when its front wheel stuck in a pit. But a few minutes late the BX2200 won't even click when I turned the key. I guess it must be something with the safety switch. What I did was to leave the speed control at Neutral (back and forth quite a few times) and the PTO off (on and off a few times). But there is no luck. I check all the fuses and they are all OK. Also the battery is working (about a year old). What else shall I do to reset the safety switch? The tractor is not level off as its front wheel are in pit. Also the fuel tank is full. Many thanks.
