Operation
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.
Cutting Speed
To improve cut quality, use a slower ground speed.
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.
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, 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 Exmark replacement
blade. Only Exmark blades are to be used with this
unit. No other blades are approved.
