Kubota L3800 Starting Issue

[Grandpa2six]

I've been fighting an intermittent no-start issue related to the electrical system of my Kubota L3800 HST for several weeks. After recently viewing a YouTube video describing a similar problem on a different model Kubota, I have made some progress in diagnosing the problem. With both PTO safety switches bypassed, I can now get the tractor to start by gently rocking the forward/reverse pedal until I find the magic position that closes the starting circuit
My problem now is that I can't find any switch associated with forward/reverse pedal. Can anyone point me to this switch, or otherwise explain how the position of this pedal affects starting?

Have a look at the illustrated parts diagrams, appears to be located at the base of the steering column with a cover over it.

It's under the steering wheel pedestal. One 12mm head bolt holding the switch bracket on. Wiggle the HST pedal by hand, watch under the steering wheel (toward the bottom of the pedestal) and you'll find it. It's real easy once you locate it.

Found it! Adjusted it. Everything working correctly now. Your help much appreciated!

The switch itself sounds that it is working.

The plunger to the switch will move when the HST pedal is in the center (neutral) position.

I would check that the springs for the HST pedal are in place and unbroken. Lube the moving components so that the pedal moves freely and centers itself.

Please let us know how that works.

Don't forget to grease the three zerk fittings under the tractor... If pedal doesn't return to middle, I grease it.

Good point.

Realized earlier mine didn't get greased when snowblower went on....
