Product Overview
This solenoid moves the fuel-control mechanism so the engine can run when commanded and shut down when the key is turned off. A sticking plunger or failed coil can mimic fuel-system trouble by causing a no-start, intermittent shutdown or engine that will not stop normally.
The 6A320-31150/31152/31153 family spans several Kubota product lines, so part-number confirmation is important. Compare the electrical connector and linkage/plunger geometry with the removed solenoid before installation.

Frequently Asked Questions
Q: Why should I match the connector and plunger?
A: Kubota used more than one stop-solenoid design across similar model families; the electrical and mechanical interfaces both need to match.
Q: What should I test before replacing it?
A: Confirm the solenoid receives the correct key-on/key-off voltage and that the linkage is free to move.
Fitment can vary by serial number, production date, engine configuration or prior repairs. Verify compatibility using the part numbers and application details listed above before ordering.
