Product Overview
The solenoid actuates the engine’s fuel-stop mechanism. If the coil opens, the plunger binds or the internal return action fails, the machine can develop a no-start, intermittent shutdown or no-key-off condition.
Kubota applications in this family include several B-Series tractors and compact excavators, but serial-number changes are common. Match the 6A320 reference, electrical connector and mechanical plunger before installation.
