OPERATING SUGGESTIONS
Engine
Your machine is powered by a twin cylinder, 4
cycle Briggs and Stratton Vanguard engine
which uses unleaded gasoline, 85 octane
minimum. DO NOT MIX OIL WITH
GASOLINE! Engine speed is controlled by
means of a throttle lever mounted on the
dash panel.
Figure 3
Interlock Switches
There are three safety switches on your
8400. They are a safety precaution which will
allow you to start your mower only when the
traction pedal is in neutral, the reel control
switch is in the disengaged position, and the
operator is seated on the tractor. If you are
able to start your mower with the pedal or
switch in any other position, adjustment of the
switched is required.
A separate Engine Manual, prepared by the
engine manufacturer, is supplied. Study the
manual carefully until you are familiar with the
maintenance, operation, adjustment and
repair of your equipment. Proper attention to
the engine manufacturer’s directions will
assure maximum service life of the engine
and highest operating efficiency.
Traction Drive Train
CAUTION: Under no circumstances
should the engine be started with
the operator or bystander standing
next to tractor or cutting units.
Power from the engine is transmitted by belt
to the variable displacement pump. The
pump supplies hydraulic fluid to the hydraulic
motors.
1. When starting the engine, the operator
must be seated on the seat, reel control
switch must be off, and traction pedal
must be in neutral (the center position).
2. The operator should practice mowing in
an open clear area to become
thoroughly familiar with the operation of
the tractor.
Reel Drive
Power to the reels is transmitted from the
engine to a countershaft shaft, which is
controlled by an electric clutch switched on
and off at the dash.
PRIOR TO STARTING THE UNIT
3. Never operate the mowers when they
are not cutting grass, as excessive
friction and heat will develop between
the bedknife and reel, damaging the
cutting edge.
4. Plan your cutting pattern to avoid any
unnecessary stops or sharp, frequent
turns. Study the area to determine the
best mowing procedure. Consider the
height of the grass and the type of
terrain (level, hilly, or rough). Each
condition will require certain adjustments
or precautions.
1. Fill the gas tank with good quality, clean,
regular unleaded gasoline, 85 octane
minimum. DO NOT use hi-test gasoline
or an oil/gasoline mixture. Fill tank to 1
inch (25 mm) below filler neck. Do not
overfill.
2. Check oil in the engine crankcase. It
should be filled to the full mark on the
dipstick. See Lubrication Specifications
in this manual for recommend oil
viscosity.
3. Check all lubrication points outlined in
“LUBRICATION on page 23.”
4. Check tires for proper inflation. See
Mower Specifications in this manual.
GB - 10

5. Before leaving the mower, always lower
wing mowers so that when exiting the
mower and stepping on the non-skid
pads of the wing mowers, it will not put
excessive strain on the lift mechanism.
6. Operate at speeds which allow you to
have complete control of the tractor and
allow you to stop the tractor or
maneuver safely in case of an
emergency. It is recommended that you
adjust the Speed Control (7, Figure 1) to
maintain a constant pedal
8. Push choke control in as engine warms
up (or immediately if engine is warm).
DRIVING THE TRACTOR
1. Position throttle at full throttle or slightly
less for optimum power and reel speed.
2. Release parking brake (9, Figure 1).
3. Moving forward: Push the toe of the
traction pedal forward with the ball of
your foot to increase the forward speed.
4. Moving backward: Push the heel of the
traction pedal in with the heel of your
foot to increase the reverse speed.
position/speed and reduce the operator
fatigue.
7. To obtain maximum mower life, the
operator must use discretion when
mowing near gravel areas (roadway,
parking areas, cart paths etc.). By
operating too close to overlapping gravel
areas, stones maybe picked up by the
mower and forced between bedknife
and reel, causing wear and serious
damage to the cutting unit.
5. To return traction pedal to neutral, rock
pedal with foot until pedal stops. The
pedal will stay in neutral when you
remove your foot.
DANGER: To avoid possible loss of
control and/or serious bodily injury,
avoid abrupt changes in the traction
pedal position. Reduce speed on
slopes, rough terrain, and in sharp
turns to prevent tipping or loss of
control.
STARTING THE ENGINE
MOWING OPERATION
1. Check the turf area for debris that would
cause damage to the reels. Never
operate the mowers when they are not
cutting grass, as excessive friction and
heat will develop between the bedknife
and reel, which will damage the cutting
edge.
2. When cutting large areas, the most
satisfactory method is to first cut the
outer area and then mow clockwise
toward the center. The next time you cut,
it is advised that you mow in the
opposite direction to prevent grass
matting.
3. Cutting speeds are governed by
conditions of turf, type of terrain, and
obstacles to be encountered. Operate
tractor at slow speeds when turning.
Figure 4
1. Open the fuel tank shut off valve (1,
Figure 4) (located by the fuel tank) on
the fuel line by turning knob
counterclockwise.
2. Sit in operator’s seat.
3. Place reel control switch in the “Off”
position.
4. Place the traction pedal in “Neutral”
position.
5. Pull choke control out and move throttle
control lever to mid position.
6. Engage parking brake.
7. Insert ignition key, turn clockwise to
“start” position, and release key when
engine starts. Do not hold key in “start”
position for more than 30 seconds or
damage to the starter may result. If
engine does not start within this time,
release the key and wait for a few
minutes before trying again.

MOWING
HILLSIDE OPERATION
1. Stop tractor by releasing the traction
pedal (8, Figure 1), then slowly lower the
mower units.
The 8400 has been designed for good
conditions. However, caution must still be
used during slope operation, especially when
the grass is wet.
CAUTION: Dropping cutting units
abruptly could damage them or the
H-frame of the wing mowers.
Wet grass limits traction and steering control.
In order to minimize the possibility of tipping,
the least dangerous method of operating on
hills and terraces is to travel horizontally to
the hill. It is also advisable to avoid any
unnecessary turns while operating on hills.
Use extreme caution and travel at reduced
speeds.
2. Engage reel control switch (10, Figure 1)
to the "On" position.
3. Depress traction pedal to the desired
speed (see Traction Pedal on page 9
and Speed Control on page 9). Reel
speed is constant and ground speed is
variable with the traction pedal. Do not
try to regulate ground speed with engine
throttle (see Throttle Lever on page 9).
1. When operating on hillsides or slopes,
maintain full engine speed, but let up on
the traction pedal as power
requirements increase. This will
maintain the performance necessary.
VERTICAL MOWING UNIT
1. Be aware that the blades can extend
below the roller. Use care when lowering
cutting units down onto a hard surface to
avoid bending the blades.
2. It is best to mow along the side of the
hill, starting at the bottom and working
upwards. This allows the machine to
negotiate the slope without mowing in a
downhill direction.
3. It is essential for the correct tire pressure
and hillside holding.
2. Setting the depth of cut: Always start
with shallow, less aggressive cuts. Set
the blades to zero (blade tips even with
bottom of roller). Gradually increase
depth of cut until suitable results are
obtained (see HEIGHT OF CUT
PUSHING OR TOWING
INSTRUCTIONS
The 8400 has a free-wheeling valve, or “tow
valve,” which will permit moving the machine
at slow speeds without starting the engine.
ADJUSTMENT on page 18).
3. Keep in mind that vertical mowing is
similar to cutting grass; you can be too
aggressive. When vertical mowing grass
that has never been vertical mowed,
avoid going too deep to start with.
Gradually increase the depth of cut to
obtain desired results.
Do not exceed 2 mph (3 km/h) while pushing
or towing (see Free-Wheeling Valve on
page 9).
CAUTION: Dropping the vertical
cutting units abruptly could damage
the blades and/or the H-frame of the
wing mowers.
AFTER OPERATION
1. Clean the entire mower after use.
Remove loose grass clippings and
caked grass to prevent clogging the
vented lubrication points and corroding
parts.
2. The engine is air cooled. Do not permit
dirt or grass clippings to accumulate on
the air intake screen, cylinder heads, or
on hydraulic pump cooling fan to prevent
serious heat damage to the engine or
hydraulic pump.
3. If fan blades become damaged, replace
the fan.

DANGER: Read and follow the
battery manufacturer’s instructions
on safety, maintenance and
installation procedures.
SERVICE AND ADJUSTMENTS
Read each instruction completely, and make
sure you understand it before making any
adjustments. Follow all the safety
precautions.
TRACTION PEDAL
ADJUSTMENTS
The traction pedal (1, Figure 15) is equipped
with a safety switch (2, Figure 15) and a
neutral centering device. The switch prevents
the engine from starting when the pedal is
positioned in reverse or forward. The
centering device locates neutral positioning of
the pump.
DANGER: To avoid possible
serious injury, before making any
adjustments or performing
maintenance, engage parking
brake, place all tractor controls in
neutral, lower cutting units to the
ground, turn ignition switch “off” and
remove key.
1. Prior to adjusting for creep, elevate the
wheels off the ground and support the
vehicle with jack stands. Any
adjustments should be done while the
hydraulic oil is warm.
2. To adjust the creep of the drive wheels,
loosen the fastener attaching the ball
bearing (3, Figure 15) to the control arm
(4, Figure 15), and move and secure the
bearing within the slot to achieve
neutral.

3. Once the traction pedal has been
adjusted, the safety switch (2, Figure 15)
may have to be re-adjusted by moving
the switch in the range of the slot
provided in the switch bracket. Adjust
the switch so that the engine cannot be
started unless the pedal is in the neutral
position.
Adjusting the hex head bolt (7, Figure 1) up
or down and locking it with the lock nut will
limit the pedal travel. Swing the speed control
away from the traction pedal to allow a full
range of forward speeds.
WING MOWER BELT TENSION
Proper belt tension allows mowers to be
driven without slippage but with belt loose
enough to be deflected slightly at a point
midway between pulleys. An overly tight belt
will cause excessive belt wear. Never allow
oil or grease to get on belt, which would
cause slipping.
1. The wing mowers must slide freely on
pull rods to allow the pull yoke springs to
properly tension the belt. If slippage
occurs, it could be due to a weakened
spring, a stretched belt, or sticky pull
rods.
2. Clean and oil pull rods frequently and
check to see that H-frames are sliding
freely on shafts.
Figure 15
LOWER COUNTERSHAFT CHAIN
ADJUSTMENTT
Chain adjustment is taken up automatically
by the torsion spring-assisted idler arm; no
adjustment is necessary. Periodically check
to see that the idler arm is free to pivot.
UPPER COUNTERSHAFT BELT
ADJUSTMENT
The upper countershaft belt is driven by the
electric clutch located on the engine stub
shaft.
Belt adjustment is taken up automatically by
the torsion spring assisted idler arm; no
adjustment is necessary. If belt slippage does
occur, check the idler arm for free movement.
If slippage still occurs, replace belt.
REAR MOWER LIFT
The rear mower lift height has been preset at
the factory and normally will not need to be
adjusted.
PARKING BRAKE ADJUSTMENT
REAR MOWER DRIVE BELT
TENSION
Rear mower belt adjustment is provided by a
spring tensioned belt idler pulley (1,
Figure 16). The idler pulley must be pressing
down on the lower portion of the rear mower
belt (2, Figure 16).
The parking brake should be set so that it
holds the tractor securely. The parking brake
must be released before the traction pedal is
engaged.
1. Adjust the brake by loosening set screw
in the brake knob and turning knob
clockwise to tighten, or counterclockwise
2. After making any adjustments, check
brake on flat ground so that the tractor
will not move with brake engaged.
3. Test further by putting tractor on a hill,
leave the engine on, and engage park
brake. Then test with the engine off.
If further adjustment is necessary due to belt
stretching, relocate the spacers (3, Figure 16)
on the pull rod pivot from position 3 to
position 4 (4, Figure 16), between the pull rod
pivot and the rear mower pull plate.
If proper tension cannot be accomplished by
the above procedure, replace the belt.
GROUND SPEED CONTROL
The speed control (see Speed Control on
page 9) is meant to ease operator fatigue by
holding the forward speed constant.

HEIGHT OF CUT ADJUSTMENT
To set the height of cut, lift the Socket/Vinyl
Figure 17
TM
Cap of the Dial-A-Height (1, Figure 17) up
then turn clockwise (viewed from above) to
lower the roller (4, Figure 17) (raise the height
of cut), or counter-clockwise to raise the roller
(lower the height of cut).
REEL TO BEDKNIFE
ADJUSTMENT
DANGER: Use heavy gloves and
be careful. Bedknife and reel blades
are very sharp.
NOTE: Each quarter turn (90°) of the
Socket/Vinyl Cap will raise or lower the height
of cut by approx. 1/32”. A full turn (360°) will
raise or lower the height of cut by approx.
1/8”.
The reel is adjusted to a fixed position
bedknife. This makes a more rugged and
durable frame and retains proper adjustment
longer. The reel adjuster bolt (5, Figure 17)
regulates the reel distance from the bedknife.
IMPORTANT: Rollers must be adjusted to the
same height so that there will be uniform
cutting the entire width of the mower.
The Height Adjustment Scale Decal (2,
Figure 17) will provide approximate height of
cut corresponding to the Socket/Vinyl Cap
rotation.
1. To reduce the distance, turn the locking
hex nut on each side of the reel down
with special reel adjustment wrench (6,
Figure 17) and then tighten top nut.
2. Proceed slowly and do not over adjust—
about 1/6 (one flat) of a turn on each
side to begin with. Do not get the reel so
tight that it is hard to turn by hand. A too
tight reel will wear much faster. The reel
should “wipe” or lightly touch the
bedknife.
3. Check to see that blades are cutting the
paper all the way across, using paper
strips held between reel and bedknife.
4. Make sure adjustment nuts are tight
before mowing.
1. Sight along the bottom edge of the
Adjuster Tube (3, Figure 17) to achieve
the desired cut height.
2. When making large adjustments to the
height of cut (over 1/2”), it is easier to
make small incremental adjustments to
each side until the desired change is
achieved, making sure the Socket/Vinyl
Cap is locked in position.
3. If very accurate cutting heights are
required, place a board or other gage
plate (of desired thickness) on a smooth
flat surface under each bedknife back
bar (1, Figure 22) and adjust the roller
height accordingly.
REEL END PLAY ADJUSTMENT
As the reel is used, normal wear of the reel
bearings will cause end play. This condition
could cause uneven wear to moving parts
and uneven cutting of turf.
GB - 18
Download from Www.Somanuals.com. All Manuals Search And Download.
Test for end play periodically by trying to
move the reel from side to side in the frame. If
there is any movement, end play is present.
DANGER: Be extremely careful not
to let tools, your fingers, or clothing
get caught in the reels. Use
approved safety glasses to protect
eyes from flying particles and
abrasives.
1. Loosen the lock nut on the adjustment
screw (7, Figure 17) and (Figure 18),
(inside right end of the reel) and turn
adjustment bolt in 1/2 turn or less. Do
not over tighten as excessive bearing
wear can occur.
2. Test again for endplay. If reel is rotating
freely and endplay can not be detected,
retighten the locking nut on adjustment
bolt.
1. Make sure to adjust the reel to the
bedknife so that the reel is parallel with
the bedknife and light contact is
maintained.
2. Reels must be run in reverse direction to
be lapped. Remove drive belts and
attach a backlapping machine to the
reel. Follow the instructions furnished by
the backlapping machine manufacturer.
Locknut
and
Screw
3. With reel running, apply the lapping
compound using a 2” or 3” wide brush.
Apply the compound evenly to the
mowing blades.
4. Stop the reel and examine both bedknife
and reel blades to see that the cutting
edges are uniformly sharp. If not,
gradually tighten nut adjuster (see REEL
TO BEDKNIFE ADJUSTMENT on
page 18), and repeat step 3 above until
the proper sharpness results.
Figure 18
5. Rinse off the compound thoroughly with
water to remove all abrasives. Check for
sharpness and readjust the bedknife if
necessary.
6. Check reel adjustment on each mower
and adjust if necessary so that they will
cut paper cleanly across the full length of
the bedknife when paper is held 90° to
the bedknife and pinched when held
horizontally.
Many types of compounds are available for
lapping. However, we recommend a good
pre-mixed water-soluble compound.
Premixed compound saves the time required
to mix, eliminates the waste, and is available
in all grit ranges from coarse to extra fine.
VERTICAL MOWING UNIT -
BLADE CHANGING
1. To change the blades, remove the
vertical mowing unit from the frame.
Unbolt the (2) hangers (see Parts
Manual) from the frame.
2. Remove bearing from the hangers.
Remove by loosening the bearing collet
setscrews.
NOTE: It is also advised to check the
bearings for wear and replace if necessary.
3. Remove nut from the shaft and slide the
blade and spacer off.
4. Reassemble with new blades. Make
sure you time the blades so they are on
a spiral and so that the blades are
pointed in the proper direction. Check to
make sure there is no side play with the
blades when tightening the nut.
Contact your local Dealer for types and
ordering information.
5. Re-attach the vertical mowing unit to the
frame.
BACKLAPPING PROCEDURE
Backlapping is a very important step in
maintaining sharp reel blades on the rear and
wing mowers.
This procedure should be performed when
the reel blades and bedknife become slightly
rounded and the grass cannot be cut cleanly
after adjusting the reel to bedknife clearance
(see REEL TO BEDKNIFE ADJUSTMENT on
page 18).

STORAGE
GENERAL INSTRUCTIONS
TIRES
When you do not plan to use your vehicle for
some time, it should be stored in a dry and
protected place. Unnecessary exposure to
the elements may deteriorate its appearance
and shorten the usual service life.
1. Before storing the vehicle, clean the tires
thoroughly.
2. Jack up the vehicle so that the load is off
the tires. If it is not jacked up, check the
tires at regular intervals and re-inflate as
necessary to keep them at the
recommended maximum pressure
(Indicated on tire’s side wall).
3. Store the vehicle so that the tires are
protected from sunlight.
ENGINE
1. Drain the fuel from the fuel tank and
carburetor.
2. Operate the engine until the gasoline in
the carburetor is completely consumed.
3. While the engine is still warm, drain the
oil form the crankcase and refill with
fresh oil. Refer to Engine Manual for
manufacturer’s instructions.
4. After engine has cooled, remove the
spark plugs and put about one
tablespoon of SAE 30 oil into the
cylinder.
5. Clean exterior of engine. Paint the
exposed metal or coat it with a light
coating of rust preventative oil.
STARTING THE ENGINE AFTER
STORAGE
If mower is cold, move the mower to a heat
location and allow it to come to room
temperature (70°F - 22°C) before starting.
This will prevent premature wear of hydraulic
system components.
Follow the towing procedure (see PUSHING
OR TOWING INSTRUCTIONS on page 12).
1. Check and recharge the battery
according to recommendations (see
CHARGING A BATTERY on page 21).
2. Reinstall the battery
3. Check oil level in crankcase and
hydraulic oil tank.
4. Fill the fuel tank with fresh gasoline.
Check fuel filter. Check fuel shut off
valve; open if necessary.
5. Before driving the vehicle, check to
make certain that the tires are properly
inflated to the proper pressure.
BATTERY
1. Remove battery and clean it. Refer to
manufacturer’s manual for specific
instructions.
2. Maintenance-free batteries should be
stored in an upright position in a cool dry
place. Storage above 80° F (28 °C)
greatly increases self-discharge. If wet
batteries are discharged, the electrolyte
will freeze when stored below
20° F (-7 °C).
IMPORTANT: The battery should be checked
every 60 to 90 days while in storage and
should be recharged if necessary.
CAUTION: Avoid injury! Explosive
separation of tire and rim parts is
possible when they are serviced
incorrectly:
TRACTOR
Wash, clean and completely lubricate the
tractor. Paint any exposed metal.
•
Do not attempt to mount a
tire without the proper
equipment and experience to
perform the job.
•
•
Do not inflate the tires above
the recommended pressure.
Do not weld or heat a wheel
and tire assembly. Heat can
cause an increase in air
pressure resulting in an
explosion. Welding can
structurally weaken or
deform the wheel.
•
Do not stand in front or over
the tire assembly when
inflating. Use a clip-on chuck
and extension hose long
enough to allow you to stand
to one side.

6. Remove the spark plugs and wipe dry.
Crank the engine (with spark plug
removed) using the starter until excess
oil has been expelled through the spark
plug hole. Replace the plug and connect
the ignition lead wires.
7. Move the vehicle outdoors or keep doors
and/or windows wide open to provide
sufficient ventilation before starting
engine. This will prevent danger from
carbon monoxide gas in the exhaust.
8. Start the engine but do not operate at
high speed immediately after starting.
Allow time for it to become properly
warmed and lubricated.
