Cutting Grass - Toro 22290 Operator's Manual

•
Keep the engine in good running condition.
•
Clean the air filter frequently. Mulching stirs up more
clippings and dust which clogs the air filter and reduces
engine performance.
•
Set the engine speed to the fastest position for the best
cutting results.
WARNING
Operating a machine with its engine running
at a speed greater than the factory setting can
cause the machine to throw a part of the blade
or engine your direction or in the direction of
bystanders, resulting in serious personal injury
or death.
– Do not change the engine speed setting.
– If you suspect the engine speed is faster
than normal, contact an Authorized Service
Dealer.

Cutting Grass

•
Grass grows at different rates at different times of the
year. In the summer heat, it is best to cut grass at the
64 mm (2-1/2 inch), 76 mm (3 inch), or 89 mm (3-1/2
inch) cutting-height settings. Cut only about a third of
the grass blade at a time. Do not cut below the 64 mm
(2-1/2-inch) setting 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, first 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 and the leaves clump on top of the
lawn, the machine may plug and cause the engine to stall.
•
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:
•
Sharpen the blade.
•
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 64 mm (2-1/2 inches) and the rear wheels at 76
mm (3 inches).
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.
•
For light leaf coverage, set all the wheels at the same
cutting height setting.
•
If there are more than 12.7 cm (5 inches) of leaves on the
lawn, set the front cutting height 1 or 2 notches higher
than the rear cutting height. This makes it easier to feed
the leaves under the mower housing.
•
Slow down your mowing speed if the machine does not
cut the leaves finely enough.
