Kubota b3200 sticking forward pedal / starting problem interlock

I was asked to look at this fairly new Kubota tractor where it would fail to start more and more. It also would creep Forward. I discovered the Forward / Reverse pedals were sticking slightly resulting in creep when you let go of the control. This sticking pedal also resulted in failure to start as the interlock would interrupt the circuit unless the pedals were jostled to find the Neutral position. I found on this fairly new tractor's linkage only required lubrication, however if yours is older and has a lot of rust, you may need to remove that shaft and work the surface smooth with like a wire wheel on desk grinder, sandpaper or similar. The fit is fairly close - overkill for what that rod does which is press the neutral safety switch. Some waterproof grease would be the best bet but since this tractor was pretty new and clean, and its stored inside, I merely lubricated it with oil from a can. I hope this helps you.
