USING YOUR ROTARY MOWER
For the best results, do not cut wet grass because
it tends to stick to the underside of the mower,
preventing proper discharge of grass clippings. If
wet grass must be cut, reduce walking speed to
help distribute the clippings more effectively.
New grass, thick grass or wet grass may require a
narrower cut. Blade speed should be adjusted to
the condition of the lawn.
The best mowing pattern is one that allows the
clippings to discharge towards the uncut part of
the lawn. This permits recutting of the clippings
to further pulverize them. When cutting high
weeds, discharge towards cut portion then recut
at right angles to first direction.
For best results, cut off one-third or less of the
total length of the grass. Lawn should be cut in
the fall as long as there is growth.
ADJUSTMENTS
A
CAUTION
Always disconnect the spark plug
wire from the spark plug and ground
it against the engine block before
making any adjustments.
CUTTING HEIGHT ADJUSTMENT
A lever at each wheel position provides cutting
height adjustment. There are five cutting heights.
Height of cut will be changed when the lever is
moved from one hoie to another. Simply depress
lever towards wheel and move wheel and lever
assembly to desired position. AM wheels must be
placed in the same relative position. See figure 6.
FIGURE 6.
HANDLE POSITION
The upper handle can be adjusted to a high or low
position. The adjustment is made by removing the
two knobs and the two curved carriage bolts and
reassembling in the other position. See figure 7.

CARBURETOR ADJUSTMENT
A
CAUTION
If any adjustments are made to the
engine while the engine is running
(e.g. carburetor), keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
All carburetor adjustments should be made with
the air cleaner on engine. Air cleaner mounting
screw must be in carburetor when engine is run.
Best adjustment is made with a fuel tank half full
of gasoline. To adjust carburetor, refer to the
separate engine manual packed with your unit.
LUBRICATION
IMPORTANT
Always stop engine and disconnect
spark piug wire before cleaning,
lubricating or doing any kind of
work on lawn mower.
Wheels—Mower is provided with ball bearing
wheels. Lubricate at least once a season with light
oil.
Also, if the wheels are removed for any reason,
lubricate the surface of the axle bolt and the inner
surface of the wheel with light oil. A 4 oz. plastic
bottle of light oil lubricant is available. Order part
number 737-0170. Engine oil may also be used.
Protective Shield—The pivot points on the protec­
tive shield should be lubricated periodically with
light oil to prevent any rust or binding up.
Chute Deflector—The torsion spring and pivot
point should be lubricated periodically with light
oil to prevent any rust or binding up. Deflector
should work freely.
