Wiring diagram for a z425 - John Deere Eztrak Special Edition Kit Z425 Z445 Z465

Hi,

You can ask John Deere to email the lawn-mower diagram to you by calling them at 1-800-356-9033.

Thank you.

Question edited for clarity, full 'make model (what it is)'.
Question moved to Category.

It sounds like you are missing the throttle return springs that returns the throttle actuator back to closed. The draft of the engine will open the butterfly valve.

Need additional information...Check to see if it is the new battery or the electrical system first........ when the battery is "up", disconnect from the system. Remove both wires from the battery...connect the next day and see if the battery will crank the mower. I've experienced new battery's that have an internal short....Let us know whether battery or John Deere electrical system.....and we can troubleshoot from there...

Concerning a Z425 John Deere mower. When I start the mower it shuts off immediately, when I try it again the motor cranks but will not start. any suggestions?
