Maintenance; Recommended Maintenance Schedule(S) - Toro 20372 Operator's Manual

•
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 2-1/8-inch (54 mm) setting unless the grass
is sparse or it is late fall when grass growth begins to slow
down. Refer to Adjusting the Cutting Height (page 9).
•
When cutting grass over 6 inches (15 cm) 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 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.

Maintenance

Note: Determine the left and right sides of the machine from the normal operating position.

Maintenance Procedure
• Change the engine oil.
• Check the engine oil level.
• Ensure that the engine stops within 3 seconds after releasing the blade-control bar.
• Clean grass clippings and dirt from under the machine housing.
• Charge the battery for 24 hours (electric-start model only).
• Empty the fuel tank before repairs as directed and before annual storage.
• Replace the air filter; replace it more frequently in dusty operating conditions.
• Change the engine oil.
• Replace the blade or have it sharpened (more frequently if the edge dulls quickly).
• Clean the air cooling system; clean it more frequently in dusty operating conditions.
Refer to your engine operator's manual.
• Refer to your engine operator's manual for any additional yearly maintenance
procedures.
•
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 one
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.
– Set the cutting height on the front wheels one notch
lower than the rear wheels. For example, set the front
wheels at 2-1/8-inch (54 mm) and the rear wheels
at 2-1/2 inches (64 mm).
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.
•
If there are more than 5 inches (13 cm) of leaves on the
lawn, set the front cutting height one or two notches
higher than the rear cutting height.
•
Slow down your mowing speed if the machine does not
cut the leaves finely enough.
