Mower blades: Stop engine and remove key.Inspect blades and sharpen or replace asneeded. Check daily or more often if needed.The machine requires more power with dullblades and gives a poor cut. If blades get bent,replace them. Blades shouldn’t have anynotches from hitting objects. The air foil on topof the blade should be sufficient to raise thegrass for cutting. If blades are in good condi-tion, sharpen at an angle of 22 to 28 degreesabout 2-1/2 inches in from the tips.Blade RemovalNOTE: Protect your hands with gloves and/or wrapblade with heavy cloth.• Remove blade bolt by turningcounterclockwise.• Install new or re-sharpened blade.• Install and tighten blade bolt securely (90ft./lbs. torque).Care should be taken to keep the blade bal-anced.
