Kubota ZD21 with electric issues

Springtx · Nov 2, 2016

I recently bought a ZD21 with 2000 hours on it. It runs and cuts great but the only way I know to start it is to push the back of the electric controller with a screwdriver. When I push in the small brass plate on the back of the small electric control box, kubota calls it a controller and it sells for $204, and turn the key it will start. Without pushing in the back of the box, nothing happens when the key is turned. I have tested all the switches and they seem to be fine. Does anyone know what would cause this and if there is a simple solution. I don't want to get the new controller if that is not the cause. The controller is toward the front right of the machine below your right hip when sitting on the machine. All 4 of the switch wires enter this small black box. Any ideas?

Unless you are going to bypass the controller and rewire the machine you can continue with what you are doing or buy the new controller.

Thanks for the advice. I wasn't sure if the problem is the controller or if there is something else causing the machine not to start the way it was meant to. I'm not planning on rewiring it or bypassing the controller so I guess I'll go the new controller route.

I have same problem with mine.I replaced ignition switch once and that solved the problem for a year or two.I finally ended up with a push button switch going to the starter.Turn ignition on and push button to start.
