This is the front wheel assembly that is used by a large number of manufactures as the standard wheel for push mowers. This wheel is a tough, black rubber wheel fitted onto a sturdy white chassis. Since it is not a pneumatic wheel, there is no concern that it will roll over hidden debris and be damaged. Push wheels such as these often last the lifetime of a Lawn Mower. However, there are occasions when the housing of the mower is dropped and the wheel becomes warped or broken. It's also the case that, with constant use, the wheels can lose tread, making them harder to maneuver in tough mowing conditions. It has also been reported that the tires will wear and become smaller in circumference over time, meaning it will require more gasoline to mow the same amount of yard. The front wheels are easily replaced. After removing the plug cap and stabilizing the mower, simply use a socket wrench to remove the center bolt from the wheel. It's a good idea to use a dry lubricant like graphite on the axle before replacing it. This OEM guaranteed replacement part is compatible with Ryobi, Yard Machines, Troy-Bilt, Cub Cadet, Husky, Yard-Man, and MTD push mowers.
