Ag. kids have rebuilt a JD B for the State Ag. Mech. Contest. Couple of question. Our tractor has a serial number of 201000 and greater (late model). Has a single gas tank but also has the second lever above the throttle to run the shutters. Judges has said that this is an all fuel tractor and should have two gas tanks if the tractor has 2 levers at the steering wheel stand. All of the tractors we have looked at have a single fuel tank but have two levers and shutters. Are the judges correct?
Also have a problem with the governor. The tractor sat for 20 years or more, was stuck when we got her. Governor works great when hooked to a dynamometer. Off the dyno she when you apply throttle engine will rep up to a high RPM but when you give it a load will smooth out some. Have made multiple adjustments to the rod to the carb and governor. Do we have a governor problem or more adjustments needed?
