USING YOUR ROTARY MOWER
WARNING
A
DO NOT operate the mower with the
chute door open unless the com
plete grass catcher is properly
mounted on the mower.
Be sure that lawn is clear of stones, sticks, wire, or other
objects which could damage lawn mower or engine.
Such objects could be accidently thrown by the mower
in any direction and cause serious personal injury to
the operator and others.
Operate a new engine at intermediate speeds and light
load for the first few hours as you would a new
automotive engine.
For the best results, do not cut wet grass because it
tends to stick to the underside of the mower, prevent
ing proper discharge of grass clippings, and could
cause you to slip and fall. New grass, thick grass or
wet grass may require a narrower cut. Blade speed
should be adjusted to the condition of the lawn.
12
Page 13
When using the side discharge mower, the best mow
ing pattern is one that allows the clippings to discharge
towards the uncut part of the lawn. This permits recut
ting 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.
This mower is designed to be operated at full throttle
to give you the best cut and do the most effective job
of bagging the cut grass.
CUTTING HEIGHT ADJUSTMENT
The height adjustment handle is located on the left side
of the deck. The handle may be placed in one of nine
cutting height positions. Push the handle to the left and
then either forward to lower the cutting height or
backward to raise the cutting height. See figure 18.
For rough or uneven lawns, move the height adjustment
handle to a position which will give a higher cutting
height.
IMPORTANT
If you strike a foreign object, stop
the engine. Remove wire from spark
plug, thoroughly inspect the mower
for any damage, and repair the
damage before restarting and
operating the mower.
Striking a solid object can cause
damage to the blade brake/clutch or
to the engine crankshaft. Extensive
vibration of the mower during opera
tion is an indication of damage. The
unit should be promptly inspected
and repaired.

MAINTENANCE
Ac warnÌn?
Be sure to disconnect and ground the
spark plug wire before performing any
repairs or maintenance.
NOTE
When tipping the unit, empty the fuel
tank and keep engine spark plug side
up.
TROUBLE SHOOTING
Refer to page 22 of this manual for trouble shooting
information.
CUTTING BLADE
To remove the cutting blade for sharpening or replace
ment, remove the two hex nuts and lock washers which
hold the blade to the blade brake/clutch. Protect hands
by using heavy gloves or a rag to grasp the cutting
blade. See figure 21.

Page 15
FIGURE 21.
When sharpening the blade, follow the original angle
of grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade will
cause excessive vibration when rotating at high speeds,
may cause damage to the mower and could break,
causing personal injury.
The blade can be tested for balance by balancing it on
a round shaft screwdriver. Remove metal from the
heavy side until it balances evenly.
When replacing the blade, be sure to install the blade
with the side of the blade marked “Bottom" {or with
part number) facing the ground when the mower is in
the operating position.
Blade Mounting Torque
Make certain that the center bolt which secures the
blade brake/clutch and the two hex nuts which secure
the blade are tightened to between 350 inch pounds
(minimum) and 600 inch pounds (maximum).
To insure safe operation of your unit, all nuts and bolts
must be checked periodically for correct tightness.
DECK
The underside of mower deck should be cleaned after
each period of use as grass clippings, leaves, dirt and
other matter will accumulate. This accumulation of
grass clippings, etc., is undesirable as it will invite rust
and corrosion and may cause an uneven discharge of
grass clippings at the next cutting.
The deck may be cleaned by tilting the mower and
scraping clean with a suitable tool or by washing with
a stream of water from a garden hose.
NOTE
Do not direct the stream of water at a
hot engine as damage to the engine
may result.
ENGINE
Refer to the separate engine manual for all engine
maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
Service air cleaner every 25 hours under norma! con
ditions. Clean every few hours under extremely dusty
conditions. Poor engine performance and flooding
usually indicates that the air cleaner should be ser
viced. To service the air cleaner, refer to the separate
engine manual packed with your unit.
The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is recom
mended at the start of each mowing season; check
engine manual for correct plug type and gap specifi
cations.
Clean the engine regularly with a cloth or brush. Keep
the cooling system (blower housing area) clean to per
mit proper air circulation which is essential to engine
performance and life. Be certain to remove all grass,
dirt and combustible debris from muffler area.
BLADE BRAKE/CLUTCH
This unit is equipped with a blade brake/clutch. If for
some reason the blade brake/clutch becomes in
operative, it is suggested that all repair work on the
blade brake/clutch should be performed by an author
ized service dealer. The unit should be inspected by
an authorized service dealer if any of the following con
ditions are noticed.
1. Frayed clutch control cable.
2. Leaking oil seal (oil collection on the floor during
mower storage).
3. Extensive vibration of the unit.
BELT REMOVAL AND REPLACEMENT
1. Disconnect the spark plug wire and ground it
against the engine.
2. Drain the fuel tank or place a piece of plastic
