Avoid Cutting Too Low
If the cutting width of the mower is wider than the mower
you previously used, raise the cutting height to ensure that
uneven turf is not cut too short.
Long Grass
If the grass is ever allowed to grow slightly longer than
normal, or if it contains a high degree of moisture, raise the
cutting height higher than usual and cut the grass at this
setting. Then cut the grass again using the lower, normal
setting.
Stopping the Machine
If you must stop the machine's forward motion, a clump of
grass clippings may drop onto your lawn. To avoid this, move
onto a previously cut area with the blades engaged.
Keep 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.
Blade Maintenance
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 cutter blades daily 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.
