This is a genuine replacement wheel assembly for several tillers. The wheels on a tiller allow the machine to move forward and backward. They roll as the tiller breaks up the soil, and help the operator to travel across the ground. Sometimes, wheels lose their seal or become damaged, which causes the tire to lose pressure and flatten. If the pressure in each tire differs, it will cause the tiller to pull to one side while operating. This makes it very difficult to control and till in a straight line. In this case, the tire may need replacing. Replacement is simple and fast and doesn't require any tools. Remove the pin in the center of the wheel, lift the front of the tiller, and remove the tire from the axle. Slide the new tire onto the axle, line up the holes and install the pin.
