I have a 2014 L4600F (2WD) tractor that will not start. Tractor was running and I turned it off to change implements, now it will not restart. Has power but starter will not engage. I have found two of the safety switches (seat, direction selector) but cannot locate the clutch and brake switches, and possibly others? Cannot find an electrical schematic or wiring diagram for this model. Any assistance is greatly appreciated. Thank you in advance.

Usually the easiest place to look is in the parts illustrations for your particular model.

I like Messicks but Kubotausa is available for those living in the USA.

Often owners shut down the tactor with the PTO still engaged and then it wont re start.

Went through and re-checked the safety switches (PTO, Seat, Direction Selector) to ensure they were in the proper position. Is the OPC the same as the seat switch? I did a continuity check all all three switches and the all checked out. All fuses are good. The system has power with the key in the "on" position, but engine will not start when key is turned to "start position". Suggestions? Not thinking starter at this time because there doesn't appear to be a voltage drop when the key is turned (no dash lights dim) or a click at the starter indicating it attempting to engage.

The clutch safety switch is often on the opposite side of the tractor by the brake pedals.

Thank you all for your assistance, found the issue. It was a broken wire in the starter safety loop. Found it by doing voltage checks between the switches. Tractor starts and runs without issue after repair. Thanks again.
