Cut only about a third of the grass blade at a time. For improved runtime, cut grass at a higher height of cut.
Do not cut below 51 mm (2 inches) unless the grass is sparse or it is late fall when grass growth begins to slow down.
When cutting grass over 15 cm (6 inches) tall, mow at the highest cutting height setting and walk slower; then mow again at a lower setting for the best lawn appearance. If the grass is too long, the machine may plug and cause the motor to stall.
Wet grass and leaves tend to clump on the yard and can cause the machine to plug or the motor to stall. Avoid mowing in wet conditions.
Be aware of a potential fire hazard in very dry conditions, follow all local fire warnings, and keep the machine free of dry grass and leaf debris.
Alternate the mowing direction. This helps disperse the clippings over the lawn for even fertilization.
If the finished lawn appearance is unsatisfactory, try 1 or more of the following:
Replace the blade or have it sharpened.
Walk at a slower pace while mowing.
Raise the cutting height on your machine.
Cut the grass more frequently.
Overlap cutting swaths instead of cutting a full swath with each pass.
After cutting the lawn, ensure that half of the lawn shows through the cut leaf cover. You may need to make more than a single pass over the leaves.
If there are more than 13 cm (5 inches) of leaves on the lawn, mow at a higher cutting height and then again at the desired cutting height.
Slow down your mowing speed if the machine does not cut the leaves finely enough.
