Product Overview
A mower that will not crank, shuts off when the controls move, or behaves as though no one is in the seat may have a failed seat switch—but bypassing it removes a safety system. This replacement restores the intended operator-presence circuit after the switch and wiring are tested.
Connector shape, mounting tabs, and normal-open/normal-closed operation must match the original.

Frequently Asked Questions
Q: Can I bypass the seat switch? A: Do not bypass safety interlocks. Replace the failed part and keep the factory protection working.
Q: Will this fix a mower that will not crank? A: It can if the seat circuit is the cause. Brake, PTO, neutral, wiring, relay, battery, and starter circuits also need testing.
Q: How do I confirm fitment? A: Match the reference number, connector, mounting tabs, and switch operation.
Q: Is bypassing the seat switch a safe test or repair? A: No. Bypassing an operator-presence circuit can allow the machine to move or keep blades engaged without the operator seated.
Q: Is this an original-equipment part? A: No. This is an aftermarket item. Brand, model, and part numbers identify fitment only; compare the original part and the listing details before ordering.
