Re: Troy Bilt Pony with only 4.7 hours of use - can't roll tractor in Neutral!
While driving slowly in forward or reverse, try shifting to neutral. If the brake disk was stuck, you would not be rolling. It will keep the tires from rotating in the same direction as it is geared directly to the differential gearset.
If your linkage were out of adjustment, trying to shift to neutral while rolling would either result in 'finding' neutral, or gear grind as you pass it and go into reverse. Neutral is just a midway position of a dog clutch in most cases, where the dogs are not touching either F or R gears.
Sometimes you can barely push on the brake/clutch, and get some clutch relief so the gears can be shifted easier. I find that doing that when down or up shifting makes the lever move easier.
If you look on the right side of the transaxle, you should see a small disk about 2.5 inches in diameter. It will have a plate across the upper or lower face, and the plate will have a lever attached that is connected to the brake clutch pedal. When you step on the brake, you move the lever, and that moves the 'ramps' to push the disk brake pad against the disk. The nut in the center of the ramp lever can pre-load the brakes or if loosened, can allow more play in the linkage before the brakes start to apply. The disk should look polished. When it gets all rusted up, it can make it impossible to turn the wheels.
