of foreign
objects,
a small object may have been overlooked and could be accidently thrown by the
mower in any direction.
5. Clear work area of objects which might be
picked up and thrown by the mower in any
direction.
6. Disengage all attachment
clutches and shift
into neutral before attempting
to start engine.
7. Dis~ngage
power to attachment(s)
and stop
engine before leaving operator position.
8. Disengage
power to attachment(s)
and stop
engine before making any repairs or adjustments.
Disconnect
the spark plug wire and
keep the wire away from the plug to prevent
accidental starting.
9. Before attempting
to unclog the mower or
discharge chute, stop the engine and be sure
the blade(s) have stopped completely.
Disconnect the spark plug wire and keep the wire
away from the plug to prevent accidental
starting.

CHUTE DEFLECTOR
To reduce the rider's shipping size, the chute
deflector on the mowing deck is placed in the
"UP" position. Before you start the engine (at
anytime) lower the deflector to its operating
position. The deflector can be returned to its "UP"
position to minimize storage space.
~CAUTION
NEVER operate the cutting unit with
the deflector in the storage position.
CONTROLS
The controls may be considered as the Drive
Control and the Cutting Control as follows:
FIGURE 9.
a. Throttle Control. The throttle control is used to
regulate the engine speed and choke the engine.
The engine should be operated from 3/4 to full
throttle when operating the cutting deck. See
figure11.
b. Gear Shift Lever. The gear shift lever is used to
shift into one of three Forward Gears, NEUTRAL
or REVERSE. See figure 11 .
FILL FUEL TANK (See figure 10.)
Fill the fuel tank completely.
Capacity is approx.
one gallon. Use clean, FRESH, lead-free or leaded
regular grade automotive
gasoline.
Do not use
gasoline that has been stored for a long period.
DO NOT

Never add gasoline to a hot engine.
Handle gasoline with extreme cau-tion.
NEVER smoke near gasoline.
It is highly explosive and fumes ignite easily.

c. Light Switch. Push the light switch up to turn
on the lights. The lights will only operate when
the engine is running. See figure 11.
d. Ignition Switch. The ignition switch is located
on the right side of the dashboard.
See figure 11. Turn the key to the START position,
to start the engine. When the engine is running,
let the key return to the ON position. To stop the
engine, turn the key to the left to the OFF position
and remove it to prevent accidental starting.
e. Clutch-Brake Pedal. The clutch-brake pedal is
located on the right hand side of the rider and is
operated by depressing it with your right foot. See
figure 12.

5.
If the engine misses,
check the spark plug
and plug wire. Dirty plugs should
NOT be
cleaned. They should be replaced.
If the engine continues to misfire with a new
plug, the problem can be loose engine bolts,
a leaky head gasket, sticky valves, etc. For
these conditions
it is suggested
a certified
service center be contacted for advice.
CAUTION
6. If the engine overheats, the cooling fins may
be clogged. Also, a too-lean fuel mixture can
cause overheating.
A slow foot pedal release will give
you a smooth engagement of power.
A fast release will jerk the rider and
should be avoided.
A new rider may jerk when power is engaged until
the belt is fully seated in the pulley groove. This is
normal and to be expected.
7.
Don't put the engine under full power as soon
as It starts.
Fast APM before the engine
warms up can cause excessive engine wear.
8. Do not idle the engine at too slow a speed for
extended
periods.
Oil will
not circulate
properJy and excessive wear can result. ..also
the engine can overheat.
The cl utch I brake foot pedal gives you positive
control in tight places and when you want to slow

through a difficult area without
moving the throttle control or down shifting.

MOWING PATTERNSThe
side discharge mowing deck will throw grass
clippings
to the right. You can take advantage ofthis
as follows:a.
If you are going to remove clippings
after you
mow, start mowing at one side of your lawn
and proceed around the lawn in a clockwise
pattern.
Using
this pattern,
th~ discharge
chute will distribute
clippings
to a center spot
for easier pick-up and removal. See figure 14.
When cutting tall, heavy grass, don't try to cut
to the desired height in one pass. Set the
blades higher than the final height and make
several passes,
gradually
reducing
grass
height.
Maintain
high engine speed at all
times
for fast blade rotation
and select
ground speed suitable for ground conditions
with the sh ift lever.
When cutting deep grass, it is recommended
that the clipping
be raked off the lawn. ..or
removed with a Trail Sweep or Vac-Sweep.
Cut the lawn before spreading fertilizer,
weed
killer, etc. Otherwise
the blade action will
suck up the material you have spread and
discharge it through the chute along with the
grass clippings.4.
FIGURE 14.
Keep in mind, however,
that in subsequent
passes a poor quality of cut can result because
the mower will have to cut BOTH grass and the
clippings
which have been thrown toward the
center of the lawn. If the clippings
are heavy
and if the grass is also heavy, the combined
load may cause the mowing deck to clog. In
such situations
it is best to mow in a counterclockwise
direction
so clippings
will not be
re-cut. See figure 15.
Mow before you water the lawn. Wet grass
clippings
are likely to cling to the underside
of the mowing deck housing.
~ CAUTION
Always check the gasoline
supply BEFORE
you start to use the tractor to be sure you have
enough gasoline in the tank to do the entirejob.
If a refill is necessary let the engine cool
before pouring gasoline
in the tank. A hot
engine
can ignite
gasoline,
causing
an

FIGURE 15.
b. If you are not going to remove grass clippings,
a mowing pattern is of no concern. However,
you should criss-cross or generously overlap
each pass to avoid missed spots. See figure

If grass develops a brown look after cutting,
the cause can be dull cutting

or
cutting was done at too slow a blade speed.
Keep the blades sharp and the engine at 3/4to
full throttle.
It is a good idea to have an extra set of blades
on hand. This will allow you to use the mower
while one set is being sharpened.
Always
have the blades sharpened
by a qualified
service Genter with proper balancing
equipment. For blade replacement
use only the
authorized original blade, see the parts list for
the correct part number.
Where grass has been trampled, it is a good
idea to rake such areas before mowing. This
will make the grass stand up for a better cut.
If you try to cut too close to small
trees the
mower can scrape or cut into the tree bark,
causing damage. It is better to adopt a policy
of cutting
reasonably close to such objects
and clipping close with hand clippers.

Your new rider will give excellent service for many
years if given reasonable care and maintenance,
as follows:
FIGURE 18. AIR CLEANER
1. Check
the
oil
level
in the
crankcase
frequently,
at least every 5 hours of operation.
When checking
oil level be sure the area
around the oil fill cap is cleaned of all debris
before it is removed. Otherwise debris can fall
into the crankcase and cause damage.
Keep the engine's air cooling fins clean.4.
Keep the underside of the mower deck clean.
BE SURE that blades are securely fastened
and are kept sharp.

5. Each time you use the rider be sure you check
the condition of the nuts, bolts, cotter pins,
etc. to be sure all are tight and secure
properly.
6. The transaxle transmission is pre-lubricated
at the factory. Check the oil level every 25
hours by removing the oil fill plug. If the oil is
below the level of the plug opening, fill to that
level with
SAE 90 extra
heavy duty
transmission oil.
Removing and Sharpening Blades. See figure 20.
Each blade is secured to the blade mount adapter
plate wtih two bolts, nuts and lockwashers.
The
blade is removed by removing
these bolts and
nuts and pulling the blade away from the adapter.
When replacing
the blades be sure the blade
offset and the sharp edges are positioned
as
shown at the right. Tighten the retaining
boltssecurely.
Do not re-use
worn
or stri pped
fasteners.
Transmission oil should be changed every 50
hours of operation or once each season.
7. The disc brake pads wear and may require
replaci ng occasionally. Th is replacement is
best done by a qualified service dealer.
& CAUTION
Brakes should be kept in good operating condition to avoid possible injury or damage to the operator or
tractor.
8. Should excessive vibration develop, check for
the cause immediately. Check for a damaged
blade, damaged bearing shaft, frayed belt, an
obstruction, etc. DO NOT operate the rider
again until the cause is found and corrected.
