OPE RATIN G IN ST R U CT ION S
A.General
1. When Mo wi n g:
a. Keep adults, children, and pets away from
the area to be mowed.
b. When operating this mower, in the forward
direction, do not allow the steering levers
to return to Neutral on their own. Always
maintain a firm grip on the levers , operate
them smoothly and avoid any sudden
movements of the lev ers when s tarting and
stopping.
c. If the mower is equipped for side dis-
charge, never use the mower without the
discharge chute installed and placed in the
down position.
d. Always remove debris and other objects
from the area to be mowed (Note: debris
and loose grass will reduce traction).
e. Mow only in daylight.
f. Wat ch f or holes, sprinkler heads, and other
hidden hazards.
g. Avoid driving too close to trees, creeks,
ditches, sand traps, and other obstacles.
h. Before backing up, check behind and
watch where you are going.
i. Always reduce speed when making a turn,
and when grass is wet.
j. Always mow across slopes, never up and
down the slope. Do not operate on steep
slopes and slow down before turning.
Avoid tur ning downhill if possible, start at
the bottom and work up to the top. Use
extra care and go slowly when turning
downhill. Control the speed and direction
of the zero turn machine “primarily” with
the speed/directional control (lap bar) of
the down hill s id e o f the machine...I .E . ,
maintain the uphill side lap bar “essentially” in a fixed position.
k. Be careful when crossing gravel paths or
roadways. Always turn off the blade clutch
switch and wait until the blades stop rotating and raise the cutting deck to the transport position. Always allow other vehicles
to have the right of way.
l. If you hit a solid object while mowing, turn
off the blade clutch switch, place the steering levers in the neutral, opened-out position, move the throttle to slow, set the
parking brake, shut off the engine, and
take the key from the ignition switch.
Inspect for damage. Repair the damage.
Make sure the blades are in good condition
and that the blade bolts are tight before
restarting the engine.
m. Nev er leave t he mower unattended without
observing the following: turn off the blade
clutch switch, placing the steering levers i n
the neutral open-out position, moving the
throttle to slow, setting the parking brake,
shutting off the engine and taking the key
from the ignition switch.
n. Never walk or stand on the discharge side
of the mower when the engine is running.
Turn off the blade clutch switch if another
person approaches while you are operating the mower.
o. Never attempt to operate the traction unit
without having the mowing deck attached.
p. Keep the mower and especially the engine
and hydraulic components clean and free
of grease, grass, and leaves to reduce the
chance of fire and permit proper cooling.
2. Safety Awareness when Mowing
a. Do not operate on steep slopes, those
above 15 degrees (27% slope).

b. Av oid turning downhill if possible, if not use
extra care and go slowly.
c. Avoid turning when going downhill, traction
is at a minimum going downhill.
d. Do not operate with discharge side of the
mowe r toward st reets, buildings, p l ay-
grounds, parking lots, other machines, ani-
mals, and other people.
e. Avoid operation or use extreme care if the
traction surface is wet, unstable, or slip-
pery.
f. Use extra care when grass clippings,
leaves, pine needles, or debris are present
as traction can be reduced.
g. Slow-down before turn ing and come to a
complete stop before any zero t urn maneu-
ver.
h. Do not stop machine or park machine over
combustible materials such as dry grass,
leaves, debris, etc.
3. To Mow Grass and Produce a Striped P attern
a. Pick a point on the opposite side of the
area to be mowed (post, tree, shrub, etc.).
b. If on an hillside, star t at the bottom so that
the turns are uphill rather than downhill.
c. Align the mower so as to head directly
toward the object on the far side.
d. Slowly increase the speed of the machine
to match cutting conditions, terrain, and
operator familiarity with the controls and
keep the machine headed directly toward
the alignment object. Do not go fast as to
reduce cut quality or to be uncomfortable
in controlling the speed and direction of the
machine.
e. When approaching the other end of a strip,
slow down or stop before turning. A U-turn
is recommended unless a zero turn is
required. The speed of a U-turn that will
allow for machine controllability and minimal turf defacement will be dependent on
several factors including: the speed of the
turn, the radius of the turn, the tire tread
pattern, the traction coefficient of the tire to
the traction surface, the slope of the traction surface.
f. Remem ber, a zero turn requires that the
forward or reverse travel of the machine be
stopped prior to the initiation of the turn or
severe turf defacement can occur.
g. To prevent rutting or grooving of the turf,
change the direction that the strips are
mowed by approximately 45 degrees the
next and each subsequent time that the
area is mowed.
B.Controls
1.
Engine Ignition and Start Switch:
(See Figure 1.) Located on the instrument housing
below the rig ht side of the operator’s seat.
When the key is inserted and turned clockwise, 45 deg ree s, the ign itio n ci rcuit is cl osed.
Turning the switch further again st spring pressure starts the engine. The engine will only
start if the blade clut ch switch is in th e “off”
position, the parking brake is engaged and
the left and right steeri ng lever s are in the
neutral, opened-out position. The ke y sh ould
always be re m oved from the swit ch if the
operator l eaves the m ower’s seat.
2.
Engine Throttle Control:
(See Figure 2.)
Located on th e left side of the mow er next to
the operat or’s seat. Mo ving th e thr ottle cont rol
from the rear to the front will increase the
engine spee d fr om slow to fast.
3.
Left and Right Steering Levers:
(See Fi gure
3.) These hinged le ve rs ope n out to the sid e in
the neutral position to permit the operator to
be seated or to leave the mower’s seat. The
operator, when sea ted, can pull the le vers up
to the operating position, a comfortable forearm’s length away. These levers control all of
the movements of the mower. Pushing both
lev ers forward causes the mower to move forward. Pulling both lev ers bac k causes the
mower to move bac k ward. Pushing one lever
ahead of the ot her lever cau ses the traction
wheel on the side where the lever is ahe ad t o
rotate f aster than the other traction wheel,
making the mo we r tu rn tow ard t he side w here
the le ver is behind. When on e l ever is pushed
forward and the other l ever pulled back the
same amount, one traction wheel will turn in
reverse a nd the mower will turn within its own
length.
In order to start the engine, both steering
lev ers must be opened out to the side in the
neutral position; the parking brake must be
engaged; and the blad e clu tch s w itch m us t be
“off”. However, once the engine starts, the
parking bra k e must be release d before the
operator pl aces the steering levers in to the
operating position or the engine will
automatically shut off.
Note:
The Steering Le ver will return tow ard
neutral when released, but they should be
placed in neutral b y the driver. If the Drive
Handles are not placed in neutral, the tractor
may creep.

Electric Blade Clutch Switch:
(See Figur e
1.) Located on the right side of the mower
beside the i gnition swit ch . Thi s i s an “on/off”
push pull switch that controls the electric
blade c l ut ch which supplies po wer to the cutting b lades through the PT O. The switch must
be turned off to start the engi ne and should
be turned off for safety any time another person approaches the mower or the mowing
deck is raised to the tr ansport position. Pow er
to the electric clutch will also be cut off if the
opera to r leaves the operator’s seat.
5.
Parking Br ake :
(See Figure 3.) Located on
the left side of t he traction unit. Th e handle is
an ov ercenter le ver which ap pl i es the drumtype brake on each drive w heel when the handle is pulle d to the rear. The brake mus t be
engaged in order to start the engine.

Deck Lift Handle and Foot Pedal Lift
Assist:
(See Figur e 3.) Located on the right
front corner of t he mowing deck . Raise the
mowing deck to the transport position, by pulling the lever to the rear and moving it inward
into the stop for transport. To lower the mowing dec k, pul l the deck lift handle and move it
outward. This lower’s the deck to the cutting
position .The foot pedal lift assist (n ot pictured
above) can provi de “li ft assist” to the ha nd
lever or with “foot effort only”. To provide
assistan ce to the lift handle: re m ove the
detent pin f rom t he pedal assembl y. Fold the
pedal down to the horizontal position so the
hole in the pe dal al i gns with the hole in the
lever. Re-install the det ent pin. Pull on the Li ft
handle an d de pres s the f oot p eda l to r ais e the
deck. Lifting with “foot effort only” depress the
foot pedal (the hand lev er will lock into transport position if f ully depres sed). To release the
lift mechanism depress the foot pedal, move
the hand l e v er out wa rd a nd slo w ly red uc e f oo t
pedal effort to lower the m echanism. To service the unit: Remove the detent pin from the
pedal assembly. Fold the pedal up to vertical
position so the hol e i n t he pedal aligns with
the hole in the lever. Reinstall the detent pin.
This is the requi red position for the foot pedal
for the foot platform to tilt forward and to
access some of the machines components.
7.
Fuel Shutoff Valve:
(See Figur e 4.) Located
on top of the fuel tank(s). When tu rned in a
clockwise direction until it stops, it will shut off
the flow of fue l to t he engine. When tu rned in
a counterclockwise direction it will open and
allow fuel to flow to the engine. Close thi s
valve if you are not going to run the mower for
a period of 30 minutes or more to pre vent
flooding the engine.
8.
Seat Adjustment Lever:
The Seat Adjustment Le ver is located beneath the seat. The
Seat Adjustment Lever is used to move the
seat fo rward and backward. To place the seat
in the desired position pull the seat adjustment lever to the left then push the seat forward or back to the desired position. Release
the lever so the seat will lock in place.
9.
Digital Tachometer and Hour Meter:
(See
Figure 1) Located on the right side of the
mower in front of the igni tion s witch. When the
machine is running the tachometer displays
engine rpm. When the m achine is off the
tachometer displays running time.
10.
Choke Lever:
(See Figure 2) The Choke
Lever is located on the left instrumen t pa nel
next to the se at. The Chok e Lever is oper at ed
manually. Having the Choke Le ver in the ON
position h el ps the engine to start during initial
start-up. During normal operation the Choke
Lever should be in the OFF position.
Note:
The Tanks equipped with E.F.I. do
not have a choke control.
Note:
There will be a flashing “LUBE” for
each recommended lubrication int erval. There
is a flashing “OIL” at each recom m ended
engine oil and filter change.

C.Initial Adjustments
1. Chec k th e fluid levels and ti res:
Note:
These checks should be made daily,
before starting the engine.
a.
Fuel:
Using a good grade of unleaded,
regular gasoline (for a gasoline engine), fill
the fuel tank (beside the engine on the left
or right side of the mower). When the fuel
reaches one inch from the top of the tank,
stop. DO NOT OVERFILL. Space must be
left for expansion.
b.
Engine Oil:
(Filled at the factory before
shipment.) Pull out the oil dipstick, wipe it
off and reinsert it. Pull it out again and read
the oil level. If it is below the operating
range, add oil through the fill tube using a
funnel to bring it up to the top of the operating range.
Note:
Gasoline Engine: Use SAE 10W30 or
SAE 10W40 engine oil, rated for service SJ.
c.
Hydraulic Oil:
(Filled at the factor y before
shipment.) The hydraulic oil tank is located
beneath the operator’s seat. Always wipe
off the area around the oil tank fill neck
before checking the oil level to prevent dirt
from contaminating the oil. Remove the
cap and make sure the oil level is up to the
lowest hole on the oil tank fill neck. The top
hole is for venting. If the oil level is low, fill
with a good grade of SAE20W-50 oil.
d.
Tires:
8-10 psi Rear, 20-25 psi Front
Caster Tires
Note:
New tires are overinflated in order to
properly seat the bead to the rim. The normal
working pressure for the traction tires is 8-10
psi. The front caster wheels should be i nflated
to 20-25 psi.
2. Check that all Nuts, Bo l ts and Screws ar e
Tight.
3. Check the tension of the deck drive b elts.
a. Remove the deck cover
b. The tension of the deck drive belts are
maintained by a spring mechanism that
adjusts for wear and stretch.
c. Examine the belts for cuts, fraying, and
excessive wear. Replace if any of these
are detected.
d. Replace the deck cover.
4.
Adjust the Mowing Deck:
The cutting height
is set any where in the range of 1- 1/2" to 5".
You may need to adjust the mo wi ng deck to
achie ve the prop er angle for mowing. Fol l ow
the procedur es below to set the appropriate
angle to the mowing deck.
a. Park the mower on a flat paved surface,
engage the parking brake, shut off the
engine, remove the key from the ignition
switch, remove connection of the spark
plugs and using the transport lever, lower
the mowing deck into the cutting position.
b. Using a ruler, pencil and paper, measure
and note the distance from the paved surface to the bottom edge of the mowing
blade at the front and the back of the deck
on each side of the mower. (Four dimensions.)
Note:
The front edge of the mowing deck
should be 1/8"-1/4" below the rear edge of the
deck so that the blades are cutting grass in
only the front half of their circular path. This
decreases fricti on and reduces the drive
power required.
c. If the dimension at the front of the mowing
deck is 1/8"-1/4" lower than the dimension
at the rear of the deck on each side of the
mower, do not adjust. If not, you will need
to adjust the Deck Lift Spring Assist (See
Figure 5). You may also need to adjust the
Deck Links (See Figure 5).
d. Lower the mower deck to the cutting posi-
tion. With a wrench loosen the inner rear
nut on the Deck Lift Spring Assist. To
adjust the deck up or down, use a wrench
and with a few turns, adjust clockwise or
counter clockwise the outer rear nut of the
Deck Lift Spring Assist. Repeat this procedure on the opposite side of the Mower.
Once the deck is adjusted, retighten bolts.
e. With the deck still in the cutting position,
adjust the Deck Links. With a wrench
loosen the top inner bolt of the Deck Link.
To adjust the side of the deck up or down
turn the top bolt clockwise or counter
Deck Li nks

clockwise a few turns. Adjust both front
and rear Deck links as necessary.
Retighten nuts.
f. Raise the mowing deck to the transport
position using the transport lever.
g. Use the transport lever to lower the mow-
ing deck to the cutting position and repeat
step “b.” above to make sure that the
desired cutting height has been attained. If
the dimensions are not correct, repeat
steps “c.” through “f.” abov e.
5. Lubricate all fittings li sted in the maintenance section.
D. Zero Turn Break-In And Operating
Procedures
DANGER:
Reread the “When Mowing” Safety Precautions.
The following procedures are suggested for operators of ride-on machines which have zero turn
capabilities.
1. Orientation:
a. Read the entire Operator’s Manual.
b. Sit on the machine, adjust the seat before-
and-after, then adjust the speed/directional
(lap bar) controls (they can be adjusted
before-and-after , as well as up-and-down
— 9/16" wrench required).
c. Become familiar w it h all o f th e ma ch ine
controls, instrumentation, safety and
instruction signs, and safety devices.
d. Move (or have moved) the machine to a
safe, level area with no obstructions including objects, pedestrians, and animals.
2. Initia l Ope rat ion :
a. Use protective equipment for eyes, hands,
hearing, feet, legs, head and other areas of
the body if needed — safety eye glasses,
gloves, earplugs, boots, hats, etc.
W ARNING:
Hearing Protection is required for all operator
exposure exceeding two (2) hours.
b. Ensure that the area is free of animals and
bystanders, especially children!
c. Survey the area where the equipment is to
be used to make sure it is free of debris,
sticks, stones, wires, bones, and other foreign objects which could cause injury to
bystanders, damage to the machine, or
damage to nearby facilities.
d. Inspect the machine to make sure:
1. All guards, shields (including mower
chute deflector) are in their proper place,
are secure, and are functional.
2. That there are no spilled or leaking fuel
or oil sources, nor loose fuel or hydraul ic
tank caps, hoses or fittings.
3. That there are no loose or missing hardware nor any missing items.
4. That no non-approved devices are
installed.
5. That all safety signs and decals are
properly installed and legible.
e. This is a one person mac hine, operator
only! Riders are not permitted under any
circumstance!
f. To start the engine on the machine:
1. Make sure the park brake is set to the
“ON” position, both lap bars are in the
neutral/start (opened-out) position, and
the Power Take Off (PTO also referred to
as blade control switch) is in the “off”
(down) position.
2. Move the choke control forward and the
engine speed control (throttle) forward
(ha l f way ) .
Note:
E.F.I. Tanks do not have a choke con-
trol.
3. Inser t the ignition key, turn the switch
toward the spring-loaded “Start” position,
maintain the Start position until the
engine begins to run, then release the
switch (it will return to the “Run” position).
4. Retard the choke slowly by moving it
rearward. If the engine is “cold”, the
choke may need to be partially applied
for a few minutes. Be sure to totally
retard the choke after the engine has
“warmed up”.
g. Check safety devices:
1. With the park brake engaged, move one
of the lap bars (speed/directional control)
from the neutral/start position to the neutral position (out of the slot, toward the
center of the machine) — the engine
should stop running. Move the lap bars
back to the neutral/start position and the
engine should run.
2. Repeat this procedure with the opposite
side lap bars.
3. With the park brake engaged and the lap
bars in the neutral/start position,
advance the engine speed control completely forward (Hi-idle), engage the PTO
control switch (pull upward), then lift off
the seat — the engine should stop running. Sit down and the engine should
13
run. Turn off the PTO by pushing the
control switch down.
h. To drive in the FORWARD direction:
1. Set the engine speed to 2000 to 2500
rpm (refer to tachometer on right control
panel). This must be increased to full
speed (3525-3675 rpm) after becoming
familiar wit h the machine.
2. Release the park brake.
3. Move both lap bars out of the neutral/
star t position to the neutral position
(toward center of machine). Slowly, move
both lap bars toward the front of the
machine until the machine begins to
move forward — release the lap bars
and the machine should stop. The more
that the lap bars are moved toward the
front of the machine, the faster the
machine will move in the forward direction. Release the lap bars and the
machine should stop traveling f orward.
(This is a safety check, the normal procedure is for the operator to slowly bring
the lap bars to the neutral position).
4. Do not advance the lap bars rapidly as
this could cause turf defacement, loss of
traction, and/or instability.
5. To turn, advance one lap bar ahead of
the other and the machine will turn
toward the opposite from the side that
was advance d — I.E. to turn clockwise
(to the Right), move the LEFT lap bar f orward more than the right side, and to
turn counter-clockwise (to the LEFT),
move the RIGHT lap bar forward more
than the left side. NOTE: If one lap bar is
in the neutral position and the other is
advanced, the turn side tire will not
rotate and a “pivot turn” will be executed
— turf defacement could occur (if on
grass) as well as potential damages to
the traction surface and the tire. If the lap
bar on the turn side is not brought all the
way to neutral, then the turn side tire will
continue to rotate and a “U-turn” will be
executed with a low potential for turf
defacement as well as traction surface
and tire damage.
i. To drive in the REVERSE direction:
1. Make sure no bystanders, animals, or
objects are behind the machine. Look
behind the machine, and use extreme
care.
2. Slowly, move both lap bars toward the
rear of the machine until the machine
begins to move rearward. Release the
lap bars and the machine should stop.
The more the lap bars are moved toward
the rear of the machine, the faster the
machine will move in the reverse direction. Release the lap bars and the
machine should stop traveling in rev e rs e
(this is a safety check, the normal procedure is for the operator to slowly bring
the lap bars to the neutral position).
3. Do not retard the lap bars rapidly as this
could cause turf defacement and/or loss
of traction.
4. To turn, retard one lap bar ahead of the
other and the machine will turn toward
the same side that was retarded — I.E.,
to turn counter-clockwise (to the LEFT),
move the LEFT lap bar rearward more
than the right side, and to turn clockwise
(to the RIGHT), move the RIGHT lap bar
rearward more than the left side. NOTE:
If one lap bar is in the neutral position
and the other is retarded, the turn side
tire will not rotate and a “pivot turn” will
be executed. Turf defacement could
occur (if on grass) as well as potential
damages to the traction surface and the
tire. If the lap bar on the turn side is not
brought all the way to neutral, then the
turn side tire will continue to rotate and a
“U-turn” will be executed with a low
potential for turf defacement as well as
traction surface and tire damage.
j. T o perform a “zero turn”:
1. Please note, a zero turn maneuver can
not be executed while the machine is
moving in the Forward or, Reverse directions, the machine must come to a stop
first.
2. To turn clockwise, slowly move the LEFT
lap bar forward while simultaneously
moving the RIGHT lap bar rearward.
Release both lap bars and the machine
should stop turning.
3. To turn counter-clockwise, slowly move
the RIGHT lap bar forward while simultaneously moving the LEFT lap bar rearward. Release both lap bars and the
machine should stop turning (this is a
safety check, the normal procedure is for
the operator to slowly bring the lap bars
to the neutral position).
3. Start the Engine:
a. Open the fuel shutoff valve.
b. Sit on the Seat. Set the parking brake
“On”.
c. M ove the left and right steering levers to
the neutral, opened-out position.
d. Turn the electric blade clutch switch “Off”.
14
e. Push the throttle control to a position a
third of the way between slow and fast.
f. Insert the key in the ignition and start
switc h and turn the switch to “On”.
g. Gasoline Engine: If the engine is cold,
push the choke to the on position.
Note:
E.F.I. Tanks do not have a choke con-
trol.
h. Turn the ignition key in a clockwise direc-
tion to the “Start” position until the engine
starts.
Note:
Do not hold the key in the “Start”
position for more than 10 seconds o r you may
damage the starter. If the e ngin e d oes not st art
in this time, wait about 30 seconds and try
again.
i. Gasoline Engine: Once the engine starts,
push the choke on halfway and as the
engine warms, push the choke off all the
way.
4.
Operatin g the Mower :
Operating a zero-turning-ra di us mower is not like operating a tractor-typ e riding mo wer . The z ero-turning -rad ius
mower is much more maneuverable and
much les s fatiguing to operate. Ho weve r, getting use d to the fingertip control of the zeroturning-radi us mower ta kes some prac t i ce.
We strongly recommend that you locate a
“test area” where you can operate the mower
for about 30 minutes without being disturbed.
a. Get into the operator’s seat.
b. Start the engine.
c. Use the transport lever to r aise the mowing
deck to the transport position. Make sure
the blade clutch switch is off.
d. After the engine has warmed, adjust the
throttle to the fast position.
e. Release the parking brake.
f. Fold in the steering levers to the operating
position.
WARNING:
When operating this mower forward, do not
allow th e steerin g levers to return to the ne utral position on their own. Always maintain a
firm grip on the steering levers, operate them
smoothly and avoid any sudden movements of
the levers when starting or stopping.
g. To go forward, move both steering levers
slightly forward and the mower will slowly
move forward. The farther you move the
levers forward the faster the mower will go
forward.
h. To back up, move both steering levers
slightly backward and the mower will slowly
move backward. The farther you move the
levers backward the faster the mower w ill
go backward.
i. To turn, pull the lever back on the side to
which you want to turn. The farther back
you pull the lever, the faster and more
sharply you will turn. Initially, you will have
to be careful to avoid tur ning to fast and
too far.
j. After you have mastered operating the
mower, use the transport lev er to lower the
mowing deck to the cutting position and
pull on the electric blade clutch switch to
start the blades rotating.
k. Practice mowing in straight passes. When
you feel confident, slowly practice mowing
around obstacles such as trees.
5. Parking the Mower:
a. Push off the electric blade clutch switch.
b. Use the Deck Lift Handle to raise the mow-
ing deck to the transport position.
c. Dr ive the mower to the cleanup or storage
area.
d. Move the throttle to slow.
e. Place the steering levers in the neutral
position.
f. Set the parking brake.
g. Turn off the ignition switch and take the ke y
from the switch.
h. Close the fuel shutoff valves.
MAINTENANCE AND

the cutting surface of the blade with a rag to
avoid injury.
a. Set the parking brake.
b. Clean any debris from the blades. Keep
blades sharp and free of build up at all
times.
c. Sharpen blades evenly at the original 30°
angle to maintain balanced cutting blades.
Do not sharpen the underside of the
blades. Use a electric blade sharpener, a
conventional electric grinder or a hand file
to sharpen the blades.
d. Replace any blade with severe nicks or
dents that cannot be removed by filing.
e. Check the balance of the blade after
sharpening by placing it on a blade balancer. Do not use un-balanced blades.
f. If the blade dips on one end, file stock off
of the cutting surface on that end.
Note:
Blades that cannot be easily bal-
anced—REPLACE.
3. Changing the Blade Drive Bel ts:
a. Set the parking brake. Remove ignition ke y
and both spark plug caps.
b. Unscrew the wing nuts from the deck cov-

Fuses:
There is on e fu se l ocat ed i n th e w iring
between the ignition and start switch and
other elect r i cal co m po nents. This is a standard plug-in type au tomotive f use rated at 7. 5
amp.
7.
Safety Switches:
There are five safety
swi tc hes in the electrica l circuit which control
the engin e. They are (1) th e blade clutch
swi tc h, (2) the parking brake sw itc h, (3) the
left and (4) the right steering lever switches
and (5) the seat switch.They operate so that
in order to start the engine, the blade clutch
swi tch must be off, the parking brake must be
engaged , and both steering levers must be
opened- out to the side in the neut ral position.
Once the engine is started, the seat mu st be
occupied and the parking brake must be
released before either of the steering levers is
folded up to the operating position or the
engine’s electronic ignition will be grounded
out and the engine will stop. Also, the seat
must be occ upied befor e the blade clutch
swi tch can cause the blades to rotate.
8.
Safety Switch Operation Checks:
The following operational ch ecks should be made
daily.
a.
Blade Clutch Switch:
Sit in the operator’s
seat. With both steering lev ers opened-out
in the neutral position and the parking
brake engaged, turn the blade clutch
switch “on” and try to start the engine. The
engine should not start. If it does, the blade
clutch switch must be replaced. If the
engine does not start, turn the blade clutch
switch “off” and start the engine. Now turn
the blade clutch switch “on” and the blades
should rotate. If the blades do not turn, the
blade clutch switch must be replaced, the
seat switch must be replaced or the electric PTO clutch must be repaired. The airgap should be checked every 100 hrs. (or
less, if severe operating conditions exist
such as when there are many on/off
cycles, mulching operations, material collection systems used, and dusty/dirty conditions), and the air-gap adjusted if more
than 0.025". To inspect , remove the “negative” cable from the batter y and all sparkplug wires. The air-gap should be checked
with feeler gages in the three slots of the
BBC (PTO Clutch). See page 22 f or air gap
adjustment specs. There are three inspection slots in the brake cover. To adjust, successively tighten each of the three gap
adjustment nuts an equal amount. Insert a
feeler gage (see page 22 for specs) into
each slot as the air gap adjustment nut are
tightened. The correct adjustment occurs
when slight contact with the feeler gage
occurs. Engage the BBC (PTO Clutch) a
couple of times, and re-check the air-gap.
If it is not between the specs listed on page
22, repeat the adjustment procedure.
b.
Parking Brake Switch:
Sit in the operator’s seat. With both steering levers
opened-out in the neutral position and the
blade clutch switch “off”, release the parking brake and try to start the engine. The
engine should not start. If it does, the parking brake switch must be repositioned or
perhaps replaced. If the engine does not
start, engage the parking brake and start
the engine. Swing one steering lever up to
the operating position and the engine
should stop. If the engine does not stop,
the parking brake switch must be repositioned or replaced.
c.
Left and Right Steering Lever Switches:
Sit in the operator’s seat. With both steering levers opened-out in the neutral position, the parking brake engaged and the
blade clutch switch “off”, swing the left
steering lever up to the operating position
and try to star t the engine. The engine
should not start. If it does, the left steering
lever switch must be repositioned or perhaps replaced. Open the left steering lever
to the neutral position and swing the right
steering lever up to the operating position
and try to star t the engine. The engine
should not start. If it does, the right steering lever switch must be repositioned or
perhaps replaced. If the engine does not
star t, Open the right steer ing lever to the
neutral position and start the engine.
Swing the left steering lev er up to the operating position and the engine should stop.
If the engine does not stop, the left steering
lever switch must be repositioned or
replaced. Open the left steering lever out to
the neutral position and start the engine.
Swing the right steering lev e r up to the
operating position and the engine should
stop. If the engine does not stop, the right
steering lever switch must be repositioned
or replaced.
d.
Seat Switch:
With both steering levers
opened-out to the neutral position, the
19
parking brake engaged and the blade
clutch switch in the “off” position, start the
engine. Now release the parking brake,
hold down on the back of the operator’s
seat against spring pressure, and swing
one of the steering levers up to the operating position. Release the operator’s seat
and the engine should stop. If the engine
does not stop, the seat switch must be
replaced. With both steering levers folded
out in the neutral position, the parking
brake engaged and the blade clutch switch
in the “off” position, sit in the operator’s
seat and start the engine. Turn the blade
clutch switch to the “on” position and the
blades should start to rotate. Raise up
slightly off the operator’s seat and the
blades should stop. If the blades do not
stop when you dismount from the operator’s seat, the seat switch must be
replaced.
e.
Electric PTO Clutch:
This clutch operates
when the engine is running, the operator is
in the operator’s seat and the blade clutch
switch is turned on.This electric clutch is a
fairly trouble free device. If a problem
develops and the blades do not turn, first
check the 7.5 amp fuse in the yellow, 16gauge wire between terminal “L” (for the
Gasoline Engine) on the ignition switch
and the hour meter and then investigate
the wiring harness and the connections to
the seat switch, the blade clutch switch and
the electric blade clutch. Then check out
the seat switch, the blade clutch switch and
finally the electric blade clutch.
D.Tires
The two front wheels are caster wheels that are free
to swivel to accommodate the direction of the Mower.
The two rear wheels are used to propel the Mower in
the direction of input from the drive handles. Inflation
pressure of the rear tires is important for stability
while the Mower is in operation. If the tire diameter is
not equal between the two tires, the Mower will pull to
one side .
1.
Inflation Pressure:
a. Traction Tires—20 psi max; 8-10 psi rec-
ommended
b. Front Caster Wheel—28 psi max; 20-25
psi recommended
c. Cutting Deck Ball Wheels—Solid Polyure-
thane.
Use the Following guidelines for maintaining the tires:
a. Balance inflation pressure between the
rear tires to help maintain straight travel
(see tire side wall for proper inflation pressure).
b. Keep the valve caps tightened to prevent
air pressure loss.
2.
Leaking Ti res:
When a flat tire occurs, repair
or replace imme diately. The normal procedure
is to remove the wheel and r epl ace it with a
spare. Take the le ak i ng tire to a maintenanc e
area and repair. If a tire is getting soft, park
the mo wer on the nearest level, paved area. If
the leaking tire is on a traction wheel, put
bloc ks on each side of the oppos ite traction
wheel and jack up the tire that leaks about an
inch off the g round. Loosen and remove the
lug nuts and remove the wheel. Mount a
spare whe el and tire , rep lace the lug nuts , and
using a torque wrench, tighten the m to 60
±
10 ft-lbs.
If the leaking tire is on a front caster wheel,
block both traction wheels and raise the
caste r whee l s o that t he tir e is a n i nc h of f t he
ground. Loosen and remove the locknut from
the axle assembly and pull the axle assembly
from the caster yoke. The wheel and two
spacer sleeves will drop free. Slip the axle
assembly through one side of the caster
yoke, through a spacer sleev e, a spare wheel,
the other spacer sleeve and finally through
the other side of the caster yoke. Then
tighten the locknut on the end of the axle
assembly.
Lower the mower off the jack and continue
mowing. The wheel with the leaking tire
should be taken to the maintenance area, the
tire inflated to 20 psi and the wheel placed in
a large bucket of water. Carefully inspect the
tire, rim and valve for escaping air bubbles
whic h indicat e a leak. Mar k each leak with a
yellow marking crayon and then deflate the
tire to 8 psi and repeat the inspection. If the
leaks you find are pin hole size to 1/16"
diameter, the tire can be repaired using an
aerosol can of tire inflater and latex sealer
available from any auto supply store. Follow
the directions on the can. If the leaks are
larger than 1/16" diameter, the tire can be
repa ired wit h r ubbe r pl ugs also availabl e in a
kit from any auto supply store. If the tire bead
is damaged, a tube will have to be installed in
the tire or the tire will have to be replaced.
3.
Creeping:
Creeping is the slight forward or
backward movement of the mo wer when the
throttle is on and the lapbars are in the
20
opened- out position. If y our mower creeps do
the following.
a. Jack up rear of unit.
b. Place Lapbars in neutral opened-out posi-
tion.
c. Locate jam nuts. (Reference control
assembly in parts list).
d. Loosen jam nuts on both ends of rod con-
nectors. See Control Assembly in the Illus-
trated Parts Book (ONLY if mower creeps.)
e. Start unit and push throttle all the way on.
f. If unit creeps forward rotate rear rod con-
nectors counter-clockwise. And if unit
creeps in reverse, rotate clockwise.
Adjust the appropriate rod connector. The
left rod for the left side of the mower and
the right rod for the right side of mower.
Afterward, retighten jam nuts.
E. Brakes
While the mower is in motion, all braking is performed
dynamically through the hydraulic pumps and traction
motors, controlled by the two steering levers. When the
mower is parked with the engine shut off, the hydraulic
system l oc ks th e trac tion whee ls .
Note:
To move the mower forward or in
reverse by pushing, you must release the
dynamic braki ng. Locate the valves on the
pump. Turn valves counter-clockwise one
quarter turn to push the unit. After pushing
the mower to t he desired location, retu rn both
valves to the oper ati ng position (See photo
below)
.
When the mower is parked with the engine running
and the steering levers opened out in the neutral
position, the parking brakes should be applied. The
parking brakes are drum-type brakes mounted on
each traction wheel.They are both engaged by the
same operating lever.
1.
Adjustments:
The parking brak e handle is an
ove rc ent er lever that should en gage with
moderat e force.
Note:
T o increase parking brake capaci ty
tighten the br ake rods going back to the brake
arms equally. Tighten rods one full turn and
check parking capacity. Repeat Step.
To adjust either brake individually, disconnect the
brake rod from the brake arm by removing the cotter
pin from the clevis pin and pulling the clevis pin from
the brake clevis. Loosen the hex nut and turn the
brake clevis in a clockwise direction one full turn
looking down the brake rod. This will tighten the brake
about .040 inch. Tighten the hex nut and reassemble
the brak e clevis to the brake shaft assembly. Normally,
both brak es should be adjusted and equal amount.
2.
Repair:
The mower is equipped wi th drum
brakes and will not normally require maintenance. If th ey are no t working pr operly, please
contact your service center.
F. Hydraulic System
1.
Hoses:
Check the hoses from the hy draulic
oil tank to the oil fil t er to the hydr aul ic lines
daily f or l eaks or abrasi on and replace any
damaged hos es. Make certain there are no
kinks or twists in any hose.
2.
Hydraulic Oil Tank and Filter:
Note:
Change the hydraulic oil and the oi l
filter after the first 50 hours of operation and
every 500 hours thereafter .
To drain the hydraulic oil tank, place a 2 gallon drain
pan under the drain plug on the bottom of the
hydraulic oil tank. Remove the drain plug, drain the
tank, then replace the plug. Place the drain pan under
the filter and remove the filter by unscrewing in a
counterclockwise direction. The filter will be full of oil,
so empty it into the drain pan. You don’t have to drain
the rest of the hydraulic system. Fill the replacement
filter with a good grade of 20W-50 oil and lubricate the
sealing surface. Screw the filter onto the filter base
until it seats an d then another one-half turn to seal.
Note:
Always wipe off the hydraulic tank fill
cap and the area around it before remo ving the
cap to prevent dirt from contaminating the oil.
Remove the fill cap and fill the tank with the same
20W-50 oil selected for the filter until the oil level is up
to the level of the second hole in the fill tube. Leave
this air space for expansion. Start the engine and let it
run at idle for about five minutes. Check the filter for
leaks. Idling the engine and the pumps in this way will
purge any air from the system. Shut off the engine
and recheck the oil level in the tank. Top-off if
Hydro Release Valve
21
necessary until the oil level is up to the second hole in
the fill tube.
Note:
After unit is up to operating tempera-
ture, turn off engine and re-check hydraulic
oil. If oil appears foamy or contains excessive
air bubble s, DO NOT OPERATE UNIT. Conta ct
service technician.
3.
Hydrostatic Pum ps and Motors:
The pumps
are the hardest-working co m ponents in the
hydr au lic sy stem. T he y ar e i n oper a tion a ll t he
time the en gine is running. Because of
ex tr em ely close tolera nces, wear i s an important factor in their life.
Contaminants
in the
hydraulic oil an d
cavitation
does the greatest
harm to the pum ps. Ca vitat ion is a b loc kage in
the supply li nes that produces a partial vacuum causi ng violent bubbling in the hydraulic
oil in the pum p.
Check the two suction hos es (the hoses connected to the filter) daily before starting the
engine. Look for a flatt ened condition or an y
leaks and repair or replace as necessary. A
flattened or leakng suction hose will permit
cavitation t o develop which can de stroy the
pumps in a sh ort time.
Contaminants or foreign matter in the oil will
also damage the pumps . To prevent t hi s, use
a filter that ca ptures particles as small as 30
microns or 30 millionths of a meter in diameter. You can help in the battle against dirt by
being very careful when you remove or repair
a component in the hydraulic system. Thoroughly cle an of f any componen t before you
work on it. Plug the ends of any hose or line
you rem ove with a rubber or plastic plug. Use
plastic caps to seal off the ends of hydraulic
fittings . Place an y compon ent you remov e in a
clean plastic bag so it can’t pick up dust or
dirt. Clean your hands frequently when working on the hydraulic components.
Note:
The pumps are not owner-repairable.
If a pump fails, contact y our Cub Cadet Commercial dealer. Do not disass emb le the pump.
4.
Steering Lever Adjust ments :
Place the
mower on level ground with t he engine running, parki ng brake off and s teering levers
opened ou t to the neutral position. If the
Mower begins to creep, adjust the S teering
Levers.
If the mo w er c re eps , firs t de termine wh ether it
creeps to the righ t or left side and which direction the mower moves — to the front or the
rear. To make the adjustment, place the steering levers in the opened-out neutral position
and set the pa rking brake , shutoff the engine,
take the k ey from the i gnition swit c h and pivot
the seat forward. If the mower creeps to th e
right, you will adjust the linkage on the left
side of the mower and vice-versa. Remove
the cap screw and lock washer that secure
the linkage control arm rod end be aring t o the
control lever pivot. Loosen the jam nut which
prevents the rod end bearing from turning . I f
the mower cr eeps f or war d, thre ad the r od en d
bearing one-ha l f t urn clockwise into the l in kage control arm. If th e m ower creeps backward, t hread the ro d e nd be aring one hal f t urn
counterclockwise out of the linkage control
arm. Then tighten th e j am nut and reconnect
the rod end beari ng to the control lever pivot
by replacing the cap screw and lock washer.
After adju st ing the steering l inkage, swing the
seat bac k t o i t s normal position and place the
steering lever on the side you adjusted up to
the operat ing positio n. If y ou f e el a sl ight p ush
forw ard or a sli ght pu ll bac kw a rd fro m the neutral positi on you must ad j us t t he l ever re turn
assembly . To do this, swing the steering lever
back out to the neutral position, pivot the seat
forward and loosen the jam nut on the lever
retu rn rod where it i s threaded into the hexshaped end of the l ever return bolt. If the
steering lever was pushed forward, turn the
hex-shaped lever return bolt clo ckwise onehalf turn off of the lever return rod. If the steering lev er wa s pulled b ac k, turn the he x shape d
lev er return bolt counterclockwise one-half
turn onto the le ver return ro d. Then tigh ten the
jam nut, pivot the se at back into the operating
position and st art the mo wer to check tha t
your adj us tments were made cor rectly.
G. Storage
1.
General:
If your mower will not be in service
for a few months, it should be st ored in a dry
location that is not subject to dra st ic c hanges
in temperature. Before storing, the following
maintenanc e procedures should be performed.
Note:
For E.F.I. Tanks, disconnect the neg-
ative lead of the battery for storage of 4 w eeks
or more.
a. Clean the mower. The entire tractor and
cutting deck should be washed and
cleaned.
b. Sharpen the blades so that the mower will
be ready to use when needed.
c. Protect the metal surfaces. Repair
scratches with the appropriate touch-up
22
spray paint. Brush a rust preventive oil on
any unpainted surfaces including the pulleys and blades. (Be careful not to get any
oil on the drive belts.)
d. Lubricate the mower.
e. Drain the engine oil. The engine should be
warm so that all the oil drains. Replace the
engine oil filter and refill the cr ankcase with
fresh oil.
f. Gasoline Engine: Drain all the fuel. Close
the fuel tank shutoff valve. Disconnect the
fuel line from the carbuetor and put the end
into an approved fuel container . Open the
fuel tank shutoff valve and drain the fuel
tank and line into the approved container.
Replace the fuel line on the carburetor.
Start the engine and allow it to run out of
fuel. This will prevent gum and varnish
deposits from forming. Replace the fuel fil-
ter.
g. Gasoline Engine Only: Rem ove the spark
plugs and pour approximately one ounce
of oil into each cylinder. Crank the engine
one or two turns to spread the oil evenly on
the cylinder walls. Replace the spark
plugs.
h. Disconnect, clean and make sure the bat-
tery is fully charged.
i. Inspect the hydraulic hoses, lines and fit-
tings. Replace as necessary.
j. Jack the mow er up and store it on block s to
take the weight off of the tires.
2. To Put the M o wer Back in Se rv ic e:
a. Check the battery. Charge if necessary.
b. Gasoline Engine Only: Rem ove the spark
plugs and wipe them off. Using th e starter,
crank the engine to pump the excess oil
out of the spark plug holes. Replace the
spark plugs and the ignition lea ds. Refill
the fuel tank with fresh gasoline.
c. Check the level of the oil in the crankcase
and the hydraulic tank.
d. Lower the mower off the block and check
the tire pressure.
e. Push the mower outdoors and start the
engine. Let the engine idle until it has
warmed up completely (4 to 5 minutes).

A. High Speed Tracking Adjustment
If mower tracks to one side with both lap bars in fully
forward position:
1. Check air pressure in all four tires:
a. Pressure should be within specified ranges
and balanced side-to-side.
b. Rear tires 8-10 psi. recommended (20 psi
MAX.)
c. Front tires 20-25 psi. recommended (28 psi
MAX.
2. Check hydraul ic f lu i d level (Re f. Engine
owne r’s man ual)
3. Verify that the mower does not creep when
the engin e is running, the lap bars are in the
neutral position and the parki ng brake is
released. (Refer to section D-3 on page 19 of
this manual if this condition exists).
4. Recheck the tracking after any adjus tments
based on the above.
5. If uneven tracking persists, adjust as follows.
(see Fig. 10)
a. Unit tracks to the RIGHT, adjust Left lap
bar stop bolt to make it longer.
b. Unit tracks to the LEFT, adjust Right lap
bar stop bolt to make it longer.
6. Re-chec k the tracki ng and make any fine tun-
ing adjustments to the lap bar stop bolts as
required.
Note:
If stop bolt is adjusted too far, tr ack-
ing problem will change sides. Make the fine
tuning adjustments by shortening the same
bolt.
B. Enginge RPM Check and Adjustment
1. Verify that the lap bars are in the neut ral position, the parkin g brake is on, and th e PTO
drive is dis engaged.
2. Start the mower and let it run at approximately
half throttl e for 3-5 minut es to bring the eng ine
up to operat i ng t em perature.
3. Locate the Hour Meter/Tachometer/ Service

scalping of high spots and uneven terr ai n
across the center section of th e deck.
2. The roller s on the fron t of the d ec k a re fixed at
the factory and can not be adjusted.
3. The rolle rs on the rear of the deck can be
adjusted downward one inch.
a. Lowering the roller will increase the strip-
ing effect left behind the mower.
b. This po s iti on ing of the rear ro lle r w ill a ls o
help to filter the mulched grass clippings
into the turf.
c. Roller should not be lowered if the cut
height is set at 2-1/2 inches or lower.
E. Lap Bar Adjustment
1. Proper lap bar and seat adjustment will result
in the following:
a. In the neutral position with hands on the
lap bars,
1. Operator’s upper arms should be relaxed
and approximately vertical.
2. Operator’s forear ms s hould be approxi-
mately vertical.
b. In the full forward position,
1. Op erator’s back should stay in contact
with the seat back.
2. Lap bars should not contact operator’s
legs.
c. In the full reverse position,
1. Lap bars should not contact the operator’s legs or torso.
2. Set the seat to the preferred operating position.
a. Adjustm ent leve r i s located under the front
edge of the se at .
b. The seat has five inches of front-to-rear
adjustment available.
4. Check factory settings of lap bars for the conditions listed above.
Note:
If lap bar adjustments are required,
height adjustments shoul d be mad e prior to
angular adjustments.
5. To adjust the height of the lap bars,
a. Remove the nut s from the lap bar mounting
bolts (see Fi g. 11).
b. Remov e t he bo lts and l ap ba r a nd rep ostion
to the seconc set of holes in the moun ting
block.
c. Replace the bolts and nut s and tighten to
28-34 ft-lbs.
1. If angular adjustments are also required,
nuts can be tightened until snug at this
point.
d. The same adjustments should be made to
both sides of the mo wer .
6. To adjust the front-to-rear angle of the lap bars,
a. Loosen the nuts on the lap bar mounting
bolts, leaving the bottom one fairly snug.
b. The top hole is slotted, allowing the lap bar
to pivot on the bottom bolt.
c. M ove lap bar to the desired angle and
tighten the nuts to 28-34 ft-lbs.
Note:
In the neutral position, the handles of
the lap bars should be aligned with approximately a one inch gap between the tips. Adjusthe gap by adding shim wash ers to the top
mounting bolt between the lap bar and the
mounting block.
d. Check the results of any adjustments to
the conditions described in section a,
above. Repeat any adjustment procedures
as required until all conditions are met.

F. Deck leveling Procedure
1. Park the mow er on a f lat pa v ed s urf ace, en gage
the parking brake , shut off the engine , remo v e
the key from the ignition s witch, disc onnect the
spark plug wires and using the transport lev e r ,
lower the mowing deck into the 4" height of cut
position. (T he 4" height of cut position is recommended in order for o ne to see and obtai n a
measurement. A ny height of cut position is
acceptable as long as a proper measure ment
can be taken.)
2. Check the right and left front tire pressure.
Adjust as necessary to 20-25 psi. Tire press ure
can aff ect blade height by as much as a 1/4”.
3. Check the right and left rear Drive tire pressure .
Adjust as necessary to 8-10 psi.
4. Measure blade-to- ground height at the front tip
of the right blade. To obtain an accurate measure, al i gn blades in p arallel with mo wer centerline, (i.e. front to back).
5. Measure blade-to- ground height at the front tip
of the left blade. Be sure to measure at t he
blade t ip with the blades arranged in proper
position.
6. To lev el the deck , adjust the ey eb olt at the left
front of the deck (Point B) so that the blade-toground h eig ht at the right front bl ade tip
matches that of the left front bla de tip . This is
done b y loosening the jam nuts on the eyebolt
and tighteni ng t he upper nut to raise the deck
and loosening the nut to lower the deck. The
right front b l ade tip height is f ixed so y ou must
adjust the left front tip to match it.
7. Measure the blade-to-ground height at the right
rear blade tip. Again be sure to measure at the
blade t ip at the rear of the right blade when
aligned along the mow er centerline. The bladeto-ground hei ght at the rear of the blade tip
should be 1/8" to 1/4” higher than the front tip.
This is referred to as blade pitch. The sam
height differenc e should be true f or the left
blade, measu red front and bac k.
8. T o adjus t the blade pitc h the dec k pitch must be
adjusted. Loosen the inner jam nu ts at the rear
of the horizont al t hreaded rods. Sta rt at Point C
to raise the rear of the deck, tighten the rear
outer jam nut to raise the deck pitch. Adju st th e
rear jam nut at P oint D to tak e the “slac k out of
the threaded rod.
9. The final adjustment would be to tak e the “s lack”
out of the lef t rear linkage (Point D) by adjusting
the jam nut s on the eyebolt. Loosen the jam
nuts and tighte n the upp er n ut to remo ve “s lac k”.
10. In many cases it will be necessary to adjust
deck height us ing both e y ebol t adjust ments an d
pitch adjustment to achie v e the correct b lade-t oground heights. If y ou remember that the front
right blade t ip adjustment is fixed and you level
to that height, adjusting the decks will be simplified.
11. Once the deck is level one may find that the
height of cut does not match the hei ght of cut
indicator . A final adjustment m ay be made by
lowering or raising the height of cut link accordingly. To raise the deck: remove th e shoulder
bolt mounting the height of cut link t o the li ft ha ndle and reassem ble the shoulder bolt in the lowest of the three h oles. To lower the deck: remov e
the shoulder bol ts m ounting the height of cut
link, flip the height of cut link around and reassemble the shoulder bolts in the top of the s et of
three holes and the bottom hole. (see Fig. 12)
