Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which enhances
decomposition and fertilization.
Mow at Correct Intervals
Normally, mow every four days. But remember, grass
grows at different rates at different times. So to maintain
the same cutting height, which is a good practice, mow
more often in early spring. As the grass growth rate slows
in mid summer, mow less frequently. If you cannot mow
for an extended period, first mow at a high cutting height;
then mow again two days later at a lower height setting.
Avoid Cutting Too Low
If the cutting width of the mower is wider than the mower
you previously used, raise the cutting height one notch to
ensure 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.

Maintenance

Note: Determine the left and right sides of the machine from the normal operating position.

When Stopping
If the machine 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.
