I needed a replacement starter for my mower and wasn’t completely sure which one would fit. I sent them a message and they got back to me quickly, asked for my model information, and helped confirm the right part before I ordered. Everything was handled professionally and the communication was great. Very happy with the service.

Safety Switch for Kubota
This safety switch is an electrical interlock component that prevents engine start or continued operation when the operator is not in a safe seat or control position, designed for use on various Kubota utility tractors. It is commonly fitted on M4-071HDCC12, M108, M5040DT, M5140HD, M5-091, M5-111, and M5140DT models.
Overview
This safety switch for Kubota tractors acts as a protective gate in the starting circuit, ensuring the engine only runs when the operator is properly seated and the transmission is in a safe state. It is an essential replacement part for maintaining operator safety on M-series and M5-series Kubota tractors. The switch is built to withstand the harsh electrical and vibration environment of agricultural machinery.

Good To Know
Q: What is the expected lifespan of this safety switch? A: With normal use, it can last several thousand operating hours, but frequent seat entry and heavy vibration may wear it out sooner.
Q: Will this switch fit both cab and open-station models? A: The same switch body is typically used across the listed M-series models, but verifying your tractor's seat assembly connections is advised.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
