as to totally surround the mower deck in uncut grass. Always try to have 1 side of the mower
deck free from uncut grass, which allows air to be drawn into the mower deck.
Avoid Cutting Too Low
When mowing uneven ground, raise the cutting height to slightly higher than normal to avoid
scalping the turf. However, the cutting height used in the past is generally the best one to
use. When cutting grass longer than 15 cm (6 inches) tall, you may want to cut the lawn
twice to ensure an acceptable quality of cut.
Cut a Third of the Grass Blade
It is best to cut only about a third 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.
Alternate the Mowing Direction
Alternate the mowing direction to keep the grass standing straight. This also helps disperse
clippings, which enhances decomposition and fertilization.
Mowing Frequency
Grass grows at different rates at different times of the year. To maintain the same cutting
height, 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.
Mow at Slower Ground Speeds
In certain conditions, mowing at a slower ground speed can improve cut quality.
Avoid Grass Clumps
If you must stop driving forward 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 or
disengage the mower deck while moving forward.
Keep the Underside of the Mower Deck Clean
Clean clippings and dirt from the underside of the mower deck after each use. Grass and dirt
build-up will eventually decrease the cutting quality.
Maintain the Blades
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 mower
blades after each use 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.
