This part is a replacement foam handle grip for lawn mowers and tillers. It is a piece of foam that fits over the metal handle of the lawn mower or tiller. The foam handle grip provides cushioning for the person operating the equipment. Using a lawn mower or tiller with a worn or missing foam handle grip can cause hand discomfort, blistering, fatigue, and more. The foam grip may wear out, crack, or tear over time or with heavy use. The foam handle grip may also degrade through exposure to extreme weather conditions, such as heat, rain, wind, and cold. A visual inspection can help determine whether it is time to replace the foam handle grip. If the foam handle grip is worn, cracking, or torn, it should be replaced. To replace the foam handle grip, take apart the handle of the lawn mower or tiller. Then, remove the old grip. Finally, lubricate the handle or the inside of the new grip.

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. This can be done in a matter of minutes.This genuine OEM replacement tiller wheel assembly is sold as an individual part and is shipped directly from the manufacturer. This part is compatible with several tillers made by MTD, Yard Man, Troy-Bilt, Cub Cadet, and Husky.

This is a V-belt made for use with several tillers made by various manufacturers. It is the component responsible for rotating the tiller tines in the tiller, and it is the primary belt used in the equipment. Each belt is made of durable rubber but can break, wear out, or stretch out over time. If these things occur, the V-belt will need to be replaced to ensure the tiller continues to do its job.As the tiller is used more often, it becomes more likely that the V-belt will need to be replaced. Mechanical failures and other issues can sometimes cause the V-belt to wear out quicker than usual. If the V-belt has become overly worn, it can cause the tiller to perform poorly since the belt might slide off of the pulley. If the belt breaks entirely, the tiller will no longer run. Before replacing the belt, remove the spark plug wire and drain the fuel.This is a genuine OEM replacement V-belt that is directly sourced from the manufacturer.
