Operating Tips
General Mowing Tips
Warning
Operating the engine on a slope greater than 45° will severely damage the engine because of a lack of lubrication. Potential damage includes stuck valves, scored pistons, or burned crank bearings.
-
Before operating the machine on a slope, complete a site survey to measure the slope where you will operate the machine.
-
Do not operate the 4-cycle Honda engine on this machine on slopes greater than 45°.
-
Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit.
-
Avoid striking solid objects with the blade. Never deliberately mow over any object.
-
If the machine strikes an object or starts to vibrate, immediately stop the engine, disconnect the wire from the spark plug, and examine the machine for damage.
-
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 the 32 mm (1.25 inch) setting unless the grass is sparse or it is late fall when grass growth begins to slow down. Refer to Adjusting the Cutting Height.
-
Mowing grass over 15 cm (6 inches) in length is not recommended. If the grass is too long, the machine may plug and cause the engine to stall.
-
Mow only dry grass or leaves. Wet grass and leaves tend to clump on the yard and can cause the machine to plug or the engine to stall.
Warning
Wet grass or leaves can cause serious injury if you slip and contact the blade. Mow only in dry conditions.
-
Alternate the mowing direction. This helps disperse the clippings over the lawn for even fertilization.
-
If the finished lawn appearance is unsatisfactory, try one or more of the following:
-
Replace the blade or have the blade 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 one pass over the leaves.
-
Slow down your mowing speed if the machine does not cut the leaves finely enough.
Maintenance
Note: Determine the left and right sides of the machine from the normal operating position.
