The mower is a Exmark Lazer ZTR, 25 kohler. A few days ago I took it off the trailer, over to the shed, parked it and that was that. Today a few days later I go to get it out and use it and it won't start. Mowers ran great all season, engine starts quickly always...well other then today. So heres what I know: ~Battery is good, eventhough turning the key nothing happens ~Engine is fine, ran perfect all season and the other day ~Won't start even if I try to jump it directly to the starter with another battery source So what im willing to bet is one on the "safety switches" like the parking brake or drive control switches are acting up and the mower thinks its not safe to start... or but not likely the blade engagement switch is broken but it was replaced earlier this season. Its not the seat sensor, I dont have one anymore (havent for 3 years). I was going to just bypass the switches today but the parking brake has more wires then I wanted to play with and the movement controls are all tucked underneath the control panel (there are switches under there right? Tomorrow I will borrow my other Lazer's parking brake switch but I really just wanted to get your guys input and see which generally act up the most? I know its one of them or it would have fired right up when I tried to jump start it. Any ideas? I am not new to working on these things just wanted to ask around here since its 1 am and im sure not going to go work on it in the cold and rain. Thanks!
