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.
