Position the new blade, blade support and blade bolt on the crankshaft and hand-tighten the blade bolt into the crankshaft. Wedge a block of wood between the mower blade and the deck to keep the blade from turning when you tighten the blade bolt. Tighten the blade bolt to 500 in.-lbs. using a torque wrench.

How to fix your Homelite gas walk-behind mower when it won't cut evenly
If the mower isn't cutting the grass evenly, first make sure that the wheels are set at the same height. If a wheel is damaged, replace it to ensure that the mower travels evenly over the lawn.
Also check that the blade is sharp and undamaged. A dull blade tatters rather than slices the ends of the grass, leaving the tips brown and dry. A damaged blade is off balance, so it cuts unevenly. Replace the blade if it's damaged.
