Good To Know
Q: How do I know if my safety switch is faulty? A: If the tractor will not start, stalls when you leave the seat, or operates intermittently, the switch may be failing. Test continuity with a multimeter to confirm.
Q: Is this safety switch plug-and-play? A: In most cases yes, as it is built to original specs. However, verify the connector shape and wire count against your existing switch before installing.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
