Tearing and shredding turns grass brown at the edges,which slows growth and increases the chance of disease.Check the cutter blades daily for sharpness, and for anywear or damage. File down any nicks and sharpen theblades as necessary. If a blade is damaged or worn, replaceit immediately with a genuine Toro replacement blade. Forconvenient sharpening and replacement, you may want tokeep extra blades on hand.DANGERA worn or damaged blade can break, and a pieceof the blade could be thrown into the operator'sor bystander's area, resulting in serious personalinjury or death.• Inspect the blade periodically for wear ordamage.• Replace a worn or damaged blade.Before Inspecting or Servicing theBladesPark the machine on a level surface, disengage the bladecontrol switch (PTO), and set the parking brake.
