Cut 1/3 of the Grass Blade
It is best to cut only about 1/3 of the grass blade.
Cutting more than that is not recommended, unless
grass is sparse or it is late fall when grass grows more
slowly.
Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which
enhances decomposition and fertilization. Avoid
mowing in reverse.
Mow at Correct Intervals
Normally, mow every 4 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 2
days later at a lower height setting.
Ground Speed
To improve cut quality, use slower ground speed. For
best operation on average lawns, operate engine at
full throttle while controlling ground speed with
transmission. Tractor should be operated at 2 to 3.5
MPH (3.2 to 5.6 kms/hr) while mowing grass.
Uneven cutting is often a result of excessive ground
speed. To correct, use low range with the high–low
lever, or reduce ground speed in high range.
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 uneven turf is not cut too short. Average
lawns are usually cut at a height between 2 and 3
inches (5–7.6 cm).
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
while driving forward with the blade(s)
"ENGAGED."
Keep the Underside of the Mower Clean
Use the washout port to 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.
