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.
When Stopping
If the machine's forward motion must be stopped while
mowing, a clump of grass clippings may drop onto your
lawn. To avoid this:
1. With the blade(s) engaged, move onto a previously cut
area.
2. To disperse the clippings evenly, raise the mower one or
two height-of-cut settings while driving forward with
the blade(s) 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. Every 30 days, check the cutter
blade(s) for sharpness and file down any nicks.
