Keeping the Underside of the Mower
Clean
Clean clippings and dirt from the underside of the mower
after each use. If grass and dirt build up inside the mower,
cutting quality will eventually become unsatisfactory.
Maintaining the Blade(s)
Maintain a sharp blade throughout the cutting season because
a sharp blade cuts cleanly without tearing or shredding the
grass blades. Tearing and shredding turns grass brown at
the edges, which slows growth and increases the chance of
disease. Check the mower blades after each use for sharpness,
and for any wear or damage. File down any nicks and sharpen
the blades as necessary. If a blade is damaged or worn, replace
it immediately with a genuine Toro replacement blade.
