Operating Tips
General Mowing Tips
-
Inspect the area where you will use the machine and remove all objects that the machine could throw.
-
Avoid striking solid objects with the blade. Never deliberately mow over any object.
-
If the machine strikes an object or starts to vibrate, immediately shut off the motor, wait for all moving parts to stop, remove the battery, and examine the machine for damage.
-
For best performance, install a new Toro blade before the cutting season begins or when necessary.
Cutting Grass
-
Cut only about a third of the grass blade at a time. For improved quality of cut, runtime, and bagging, 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.
-
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.
