Operating Tips

General Mowing Tips

  • Avoid striking solid objects with the blade. Never deliberately mow over any object.

  • For best performance, install a new blade before the cutting season begins.

  • Replace the blade when necessary with a Toro replacement blade.

Cutting Grass

  • Cut only about a third of the grass blade at a time. 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.

Cutting Leaves

  • 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.

After Operation
