The blade can be tested by balancing it on a round shaft screwdriver. Remove metal from the heavy side until it balances evenly. It is recommended that the blade always be removed from the adapter when testing for balance. Before reinstalling the blade and the blade adapter to the unit, lubricate the engine crankshaft and the inner surface of the blade adapter with light oil.

Be sure to install the blade with end tips facing up or the side of the blade marked “Bottom” (or with part number) facing the ground when the mower is in the operating position.

Slide the blade adapter onto the engine crankshaft.

Place the blade on the adapter. Be certain the blade is aligned and seated on the blade adapter flanges.

Place blade bell support on blade. Make sure the notches on the blade bell support are aligned with small holes in the blade.

Replace hex bolt and tighten hex bolt to torque: 450 in. lbs. min., 600 in. lbs. max.

NOTE: To ensure safe operation of your mower, the blade bolt must be checked periodically for correct torque.

Drive Belt Removal And Replacement

Disconnect the spark plug wire and ground it against the engine.

Drain the fuel tank or place a piece of plastic beneath the cap to prevent gasoline leakage.

If unit is tipped for easier access to belt, tip the mower back on its side with the air filter side away from the ground.

To get easier access to the belt, just securely place the mower on raised blocks.
