Product Overview
A mower that cranks only when the key is wiggled, loses dash power, or starts and dies when the key returns to RUN may have worn contacts inside the switch. Battery cables, safety interlocks, relays, and the fuel-shutoff circuit can cause similar symptoms, so check them before ordering.
The switch routes battery power through OFF, RUN, PREHEAT, and START positions on the matching machine. The diesel glow-plug terminal is especially important; a look-alike switch with the wrong pinout can create a no-start condition.
Match 183827 or 1E013-63590, connector and terminal lettering, bezel, key positions, engine, mower model, and serial number. Do not choose by key shape alone.

Frequently Asked Questions
Q: Why does the mower start but stop when I release the key? A: The RUN contact may be worn, but the fuel-shutoff circuit, relay, wiring, or safety system can behave the same way.
Q: Will it fit every Grasshopper with a Kubota engine? A: No. Match the machine serial number, original switch number, functions, and terminal layout.
Q: Does it include the key? A: The listing is for the switch and matching keys shown in the product photos.
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.
