Key

This metal square key is designed to prevent the rear wheel of your lawn equipment from slipping. Approximately sized at 3/16 x 2, it fits into the groove found on the axle and the hub of the wheel, ensuring proper alignment of the two parts. If the machine becomes hard to turn or maneuver or it makes a grinding or clicking sound, your square key may be worn out. Visually inspecting this part for bends and cracks can confirm this. You may also notice that the rear wheel is wobbling or falling off. A worn square key can cause damage to the wheel assembly of the machine, leading to costly repairs or even the need to purchase a new one. To prevent that, you need to replace a broken square key as soon as possible. Replacing the square key is a simple process. After turning your lawn equipment off and letting it cool down, you need to use a jack to lift the rear of it off the ground. Remove the wheel from the axle by using a socket to remove any bolts or nuts holding it in place. With pliers, you can then take the square key off the machine. This replacement part is sold individually and is sourced directly from its original manufacturer.
