Product Overview
A tractor that shows no dash power, will not send a starter signal, or cuts out unless the key is held at an angle may have a worn switch. Battery, fuse, neutral and clutch interlocks, relays, stop solenoid, and connector condition must also be tested.
The key switch distributes OFF, RUN, and START power through the original tractor harness. It does not bypass safety switches, and a look-alike switch with a different pinout can damage wiring.
Match the original reference, four-terminal layout and letters, connector, mounting threads, key positions, tractor transmission suffix, serial number, and product photos.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application that is not shown above. Model year, production date, serial number, engine or equipment specification, installed options, and previous repairs can change fitment. Match the original part, reference number, dimensions, connectors, mounting points, and product photos before purchase.
Frequently Asked Questions
Q: Can this switch cause the tractor to crank but not run? A: A failed RUN contact can, but fuel-shutoff power, wiring, and fuel delivery should also be checked.
Q: Does it fit every L3901? A: No. Match serial, connector, terminal layout, and original part number.
Q: Why are several 34670 numbers listed? A: Kubota service revisions are commonly cross-referenced, but the physical and electrical match still needs confirmation.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
