Hello, i went to start my MZ54 for the year and i got nothin! i have the park brake and all the levers in the right position and its acting like one of them is in the wrong place. I ended up jumping the starter and got the mower running and went to test each of the saftey switches by moving said lever and they are all trying to kill the motor. I thought that the seat switch was bad because when i jump the mower and go to remove the park brake it tries to kill the mower as if noone is in the seat so i thought that it would be the seat switch but i was reading and someone actually said that it would be the park brake switch that is bad in that case? can someone confirm or deny for me? thank you!
