The Kubota generators are available with both single and three-phase output in a heavy duty 2-pole as well as 4-pole configurations.

Starter does not initialize.

Motor not working. If you observe that the motor is not operating or the cylinders that are responsible for firing the fuel are not working, it’s time to check the glow plugs or the wires connecting to glow plug.

Engine overheating. For steady operation, the engine should maintain a cool temperature but if the Kubota generator panel is indicating overheating you need to check the levels of coolant and engine oil. Apart from this, the other causes may include defective radiator fan or overload condition.

    Kubota OC95 5750 watt generator will produce 220v if I manually hold the throttle open. It does not accelerate on its own. Cranks right up and has low hours although it is 5years old. Any suggestions for parts?

    I’m working on a Kubota Generator ARX6500-B, Ser#:551413 At times will run fine, but after awhile it’ll start acting like there is water in the fuel. I have drained the fuel twice in this unit, and it just seems to be getting worse. I have tried everything I can think of. Do these units just have issues. This unit is for a client, and I’m at a loss as to the possible problem.
