Mower Blades

WARNING: The mower blades are sharp and can cause severe injury. Always protect hands by wearing heavy leather work gloves to grasp blades.

It is extremely important that each cutting blade edge be ground equally to maintain proper blade balance. An unbalanced blade will cause excessive vibration when rotating at high speeds, may cause damage to the unit, or result in personal injury. The blade can be tested by balancing it on a round shaft screwdriver. Grind metal from the heavy side until it balances evenly.

When replacing the blade, be sure to install the blade with the side of the blade marked “Bottom” (or with a part number stamped in it) facing the ground when the mower is in the operating position.

IMPORTANT: Tighten the hex nut that secures mower blade to spindle to 100 ft-lbs.

WARNING: Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary.
