Question about Craftsman 20 hp 42 in. Deck Lawn Tractor - CA Model
Have mowed once this year with no problems. new battery put in, no mice in engine. starts fine but dies when brake released or mower deck engaged. thought engine would not start if switch in seat not activated
You likely have a faulty operator presence seat switch. This switch is designed to shut down the engine if the operator leaves the seat without shutting off the PTO and engaging the parking brake. An easy way to tell if the seat switch is bad is unplug the switch from the wiring harness receptacle. Jumper the wiring harness receptacle. Start the engine and disengage the brake. Engage the blades. If the engine doesn't shut off, replace the seat switch. They're not expensive, and you really should keep all your mower's safety features operational to help protect you from any potential liability.

The first thing I would check is to make sure the drive belt is not binding somewhere.

It may think you are in reverse and is killing the motor to keep you from backing up with the blade running. Look for switch that is telling it when you are in reverse, maybe it is stuck with grass or other debris. another possibility is that the blades are jammed and they are stalliing the motor. Mines stalls easily when cold.

cut the wires running to the switch...try again...if same, stripp back wires, and twist together...wrap in tape or use some sort of connector...it's electric and should be treated as such...try again...still ?? Start finding those switches and repeat the process til it works...theres usually 3 or 4...
