Good To Know
Q: How do I confirm this switch fits my tractor? A: Cross-reference your tractor's model number, including the suffix letter, with the listed compatible models before ordering. The switch is designed to match the original mounting hole and wiring connector, but serial-number differences can occur.
Q: Can I install this myself? A: Yes, it typically involves disconnecting the battery, removing the old switch from the dash, and connecting the new unit to the existing wiring harness. Use a multimeter to verify the correct terminal positions if the wiring colors are not labeled.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
