Wiring Diagram / Kubota 3rd Function solenoid triggers

bozowise · Jun 22, 2014

I have the factory Kubota 3rd function valves on my L4760 HSTC w/ 1055 loader. The factory toggle is on the loader stick with a momentary switch. I want to add inline a toggle so I can use the 3rd function to operate a motor without having to hold the momentary switch down.

I haven't had time to get in there and take things apart and put a meter on everything, was hoping that someone had a diagram before hand so I wouldn't have to go probing for the correct interface wires.

The sudden open/close action of a solenoid valve is Not correct for a hydraulic motor... You will break things.

I am aware it's not correct but I have been running my auger off this same solenoid type setup for years with no trouble. I just need to wire the switch on this new tractor.

Actually you should be able to get away with wiring in a toggle switch that is fused and feeds power to the solenoid that gives the correct hydraulic flow. As long as no one presses the momentary switch on the loader stick while your toggle switch is on nothing adverse should happen.

The 3rd function kit it is part number L2265 without pulling the skid plate there appears to be 2 relays operating the 2 solenoid packs.

Yes on my last one which was an after market solenoid 3rd function I wired the toggle to not only activate the solenoid but to also interrupt the momentary switch making it nonfunctional unless the dpdt toggle was in the neutral position.

I was just hoping I could get a color wiring schematic from a member here to save me the time from probing everything mapping out the kit electrical functions. I can do it and have the knowledge to setup the relays once I know what all is happening with the current writing, but it have a newborn and no free time to be probing so I'm here rocking a kiddo and typing on the web.
