1. SAFETY
1.1 SAFETY ALERT SYMBOL
THIS SAFETY ALERT SYMBOL IS USED BOTH IN THIS MANUAL AND ON
THE MACHINE TO IDENTIFY IMPORTANT SAFETY MESSAGES WHICH MUST BE
FOLLOWED TO AVOID ACCIDENTS. THIS SYMBOL MEANS:
ATTENTION! BECOME ALERT!
YOUR SAFETY IS INVOLVED!
The safety alert symbol appears above information which alerts
you of unsafe actions or situations and will be followed by the
word DANGER,WARNING, or CAUTION.
When used with the word DANGER: IT DENOTES THAT AN EXTREME HAZARD
EXISTS WHICH WOULD RESULT IN HIGH PROBABILITY OF DEATH OR
IRREPARABLE INJURY IF PROPER PRECAUTIONS ARE NOT TAKEN.
When used with the word WARNING: IT DENOTES THAT A HAZARD EXISTS WHICH
CAN RESULT IN INJURY OR DEATH IF PROPER PRECAUTIONS ARE NOT TAKEN.
When used with the word CAUTION: IT DENOTES A REMINDER OF SAFETY
PRACTICES OR DIRECTS ATTENTION TO UNSAFE PRACTICES WHICH COULD
RESULT IN PERSONAL INJURY IF PROPER PRECAUTIONS ARE NOT TAKEN.
1.2 TRAINING
1.2.1 Regard the Exmark mower as a piece of power equipment and
teach this regard to all who operate this unit.
1.2.2 Read the instructions carefully. Familiarize yourself
with the controls and the proper use of the equipment.
1.2.3 Never allow children, teenagers, or people unfamiliar
with these instructions to use the mower.
1.2.4 Avoid mowing while people, especially children or pets,
are nearby. Keep in mind that the operator or user is
responsible for accidents or hazards occurring to other
people or their property.
1.3 PREPARATION
1.3.1 The use of personal protective equipment, such as (but not
limited to) protection for the eyes, ears, feet and head
is recommended.
1.3.2 While mowing, always wear substantial footwear and long
trousers. Do not operate equipment when barefoot or when
wearing open sandals.
1.3.3 Thoroughly inspect the area where the equipment is to be
used and remove all stones, sticks, wires, bones and
other foreign objects, which may damage the equipment or
cause personal injury to the operator or bystanders.

•
••
•Fuel is Highly Flammable. DO NOT smoke
while refueling. Refuel only in a well
ventilated area, or refuel outdoors.
•
••
•Store fuel in containers specifically
designed for this purpose.
•
••
•Add fuel before starting the engine.
Never remove the cap of the fuel tank
or add fuel when engine is running or
when the engine is hot.
•
••
•Never fill the fuel tank so that the fuel
level rises above a level that is 1/2” below
the bottom of the filler neck to allow for
fuel expansion and prevent fuel spillage.
•
••
•If fuel is spilled, DO NOT attempt to start
the engine. Move away from the area of the
spill and avoid creating any source of
ignition until fuel vapors have dissipated.
1.4 OPERATION
1.4.1 Give complete, undivided attention to the job at hand.
1.4.2 Mow only in daylight or in good artificial light. DO NOT
operate the mower when children or others are in the area.
1.4.3 When feasible, avoid operating the equipment in wet grass.
1.4.4 Use EXTREME caution when mowing and/or turning on slopes as
loss of traction and/or control could occur. Mow across slopes
with walk behind mowers, never up and down. Loss of control
and/or loss of operator’s footing could result in a fall with
an arm or leg getting under the mower or engine deck and
sustaining serious injury. Drive slower on slopes. DO NOT
operate on slopes greater than 20 degrees. Watch for ditches,
holes, rocks, dips, and rises which can cause erratic
handlebar movement and loss of footing. Keep away from drop-
offs and steep banks. Avoid sudden starts. Look down and
behind you before and while moving backwards. DO NOT mow
slopes when grass is wet - slippery conditions create
hazardous footing, affect steering, and reduce traction and
braking. The operator is responsible for safe operation on
slopes. See inside back cover to determine the approximate
slope angle of the area to be mowed.
1.4.5 Stop the blades when crossing surfaces other than grass,
if mower must be tilted for transportation, and when
transporting the mower to and from the area to be mowed.
1.4.6 Never operate the mower with defective guards, shields, or
covers. Always have safety shields, guards, switches, and
other devices in place and in proper working condition.
1.4.7 Do Not change the engine governor settings or overspeed
the engine. Operating an engine at excessive speed may
increase the hazard of personal injury.
1.4.8 Place transmission in neutral, disengage blades, and latch
drive levers in “park brake” position before starting engine.

- 3 -
1.4.9 Start the engine carefully with feet well away from the blades.
1.4.10 Keep hands, feet and clothing away from rotating parts
while the mower is being operated.
1.4.11 Stop the engine and disconnect the spark plug wire(s)and/
or remove key:
a) Before checking, cleaning or working on the mower.
b) After striking a foreign object (inspect the mower for
damage and make repairs before restarting and
operating the mower).
1.4.12 Stop the engine:
a) Before clearing blockages.
b) Before removing the grass catcher.
c) Whenever you leave the mower.
d) Before refueling.
e) Before making height adjustments.
1.4.13 Before stopping the engine, return the throttle control to the
idle position for 30 seconds to allow the engine to cool down.
1.4.14 The fuel system is provided with a shut-off valve. The
fuel shut-off valve is used to shut off the fuel when:
a) The machine will not be used for a few days
b) During transport to and from the job
c) When parking inside a building
1.4.15 This mower was designed for one operator only. Keep all
others away from mower during operation.
1.4.16 Do Not mow without the grass deflector or entire grass
collection system in place and in proper working condition.
•
••
•DO NOT operate the engine in a small
confined area where dangerous carbon
monoxide fumes can collect.
•
••
•Failure to follow safety instructions
and cautious operating practices can
result in serious injury.
•
••
•Although hazard control and accident
prevention partially are dependent upon
the design and configuration of the
equipment, these factors are also
dependent upon the awareness, concern,
prudence and proper training of the
personnel involved in the operation,
transport, maintenance and storage of
the equipment. It is essential that all
Operator Safety Mechanisms be connected
and in operating condition prior to use
for mowing.

3. ASSEMBLY INSTRUCTIONS
3.1 Uncrate unit, leaving it on the pallet, place upper handle
assembly, fuel tank, and shifter lever at the rear of the
machine. Place casters at the front of the unit.
3.2 Place a length of 4" x 4" block between the front of the
cutter deck and the pallet.
3.3 Remove the bolt bag from the top of the fuel tank support.
3.4 Refer to Parts Manual to help you identify and locate parts
and their proper position.

- 9 -
3.5 Install casters to front of deck using appropriate
hardware from the bolt bag (eight 3/8 x 3/4" bolts
and eight 3/8" whizlock nuts); tightening the lower
four bolts first, then the top four.
3.6 Loosen the 5/16" hardware at the two (2) discharge
deflector hinge points so that the deflector is snug,
but can be moved up and down freely.
3.7 Mount the fuel tank on the tank support.
Apply retaining adhesive Fel-Pro Pro-Lock ‘Retaining Type I or
Retaining II’ or Loctite RC 609 or 680 on the two threaded
studs from the bolt bag and install into the two left holes
underneath fuel tank. Install the fuel tank on top of the
fuel tank support with the studs going through the slots in
the support. Install two 5/16 x 3/4 screws with a 5/16”
flatwasher and 5/16” lockwasher into the threaded holes in
the right side of the fuel tank. Do not over tighten. Place
a 5/16” flatwasher, then a spring, and a 5/16 nyloc nut over
each of the studs. Completely tighten nyloc nut then back off
a 1/2 turn. This will allow for normal fuel expansion and
contraction with changes in temperature and fuel levels.
Do not over tighten.
3.8 Install Handle Assembly
Position the lower end of the handle assembly on the
outside of the upper rear section of the fuel tank &
handle support. Install one 3/8-16 x 1" bolt (from
the outside in) in the upper hole on each side of the
handle.
Loosely secure each screw with a 3/8" nyloc nut. The
handle can now be pivoted to allow positioning in one
of the three holes allowing various adjustments for
operator comfort (See Figures 1 & 2). Once a proper
position is found, install one 3/8 x 1" bolt in the
bottom mounting holes on each side of the handle.
Secure each bolt with a 3/8" nyloc nut. Tighten all
hardware.
FIG. 1
UPPER HANDLE MOUNTING
IMPORTANT: If the mower has been completely assembled and
the handle position is changed, it will be necessary to
readjust the drive and brake linkage.

FIG. 2
UPPER HANDLE
HEIGHT ADJUSTMENT
3.8.1 Attach throttle cable to engine.
For Kohler, Kawasaki, and B&S 10.5 hp Engines with "positive"
detents in throttle cable for both idle and full throttle
positions.
a)Position the throttle control lever (on console) in
the full throttle (but not choke) position. You
will feel a detent when the throttle control lever
is approximately 3/4" from the upper end of the
slot -- this is the full throttle position.
b)Route the throttle cable along the right side of
the upper handle, under the fuel tank support and
to the left side of the engine.
c)Loosen clamp on engine control plate. (See Figures
3, 4 and 5). Attach inner wire of the throttle cable
to the control plate lever and position cable under
clamp, do not tighten clamp.

FIG 5
B&S 10.5 hp SPEED CONTROL
(THROTTLE CABLE HOOK-UP)
d) Pull cable upward (rearward for B&S) until alignment
holes in control plate lever and control plate line up.
For Kawasaki a 15/64 drill bit can be inserted through
these two holes to align them. For Kohler use a 19/64
drill bit. For B&S 10.5 hp use a 1/8” drill bit. Once
holes are aligned, tighten clamp onto throttle cable.
e) Check that the choke adjusting screw just comes in
contact with the choke lever when throttle control
is in the full throttle position. (B&S 10.5 hp does
not have a choke adjusting screw.) Choke link should
not move when throttle control is moved to the full
throttle position. Be sure choke is fully closed
when throttle lever is moved fully forward to the
"CHOKE" position.
f) This step needs to be done after the unit has been
assembled and the engine has been started. Refer
to Section 4 (Operation Instructions). Check the
engine "STOP" position by moving throttle control
fully to the rear. (Note: There is a detent toward
the lower end of the slot in the console for "IDLE"
"STOP" position is rearward from this detent). For
Kohler, if engine continues to run in the "STOP"
position, turn kill switch adjusting screw inward
until engine stops, then give it an additional 1/2
to 3/4 turn to assure it will always function
properly.
(Kawasaki and B&S 10.5 hp kill switchs are not adjustable).

1/8" from the lower end of the slot. Route the
throttle cable along the right side of the upper
handle, under the fuel tank support, and position
the cable on the left side of the engine.
b) Attach the inner wire to the appropriate throttle
control slider on the engine. Loosen the cable
clamp on the engine, place the cable behind it and
push ahead on the cable to move the throttle
linkage to the "stop" position. Tighten the cable
clamp screw.
3.8.2 Attach the fuel tank hose to the tank fitting and
secure with the clamp provided.
3.8.3 Install the blade engagement linkage to the bell crank
on the Left Hand side of the engine deck. Insert rod
through the hole from the outside and fasten with
cotter hairpin.
3.8.4 Install and adjust shifter lever.
a) Remove the 3/8" nyloc nut and spring disc washer from
the stud on top of the transmission. Install the
shifter lever through slot in shifter lever plate
and onto the stud on top of transmission. Be sure
the square-hole washer remains between the lever
and transmission. Replace the spring disc washer and
nyloc nut (See Figure 6). Torque the 3/8" nut to
35 ft. lbs. (47 N⋅m).
b) Shift lever to second gear and check alignment of
lever in slot of shifter plate. Clearance between
top of lever and the top of the slot should be
about equal to the clearance between bottom of the
lever and the bottom of the slot (See Figure 7).
If it is not, remove lever and bend it slightly to
adjust. DO NOT bend lever while it is attached to
transmission. Reinstall lever and tighten hardware.
c) Shift to neutral position. Lever should not contact the
left edge of the upper slot. Push lever down. Lever
should not contact the right edge of the bottom slot
(See Figure 8). Shifter plate can be adjusted Side to
side to adjust position of lever relative to the slot in
plate. Loosen the two bolts securing the shifter plate
to the shifter lever legs. Adjust shifter plate and
retighten bolts.

NOTE: Neutral lock/park brake latch clearance should be
checked when there is a slight upward force placed
on the drive levers to remove any "slack" in the
linkage.
After clevis pin has been inserted, install hairpin into
hole on the clevis pin between the neutral lock/park brake
latch and drive lever (See Figure 11). Repeat procedure on
opposite side of unit.

3.8.6 Adjust brakes by adjusting wingnut on the upper end of each
brake rod. Position the wingnut so the brakes will engage
when the drive levers are squeezed enough to place the
neutral lock/park brake latches into the “park brake” position.
NOTE: The neutral lock/park brake latches must be able to be
moved into the park brake position, if not, the brake
linkages must be adjusted again.
3.8.7 Squeeze the drive levers and move both neutral lock/park brake
latches to the rear into the neutral lock position. Mower should
move forward and backward freely, if not, readjust the brakes.
Squeeze the drive levers and move the neutral lock/park brake

3.8.8 Route the long, unattached wiring harness lead up the left
hand side of the handle and connect the two leads, in any
order, to the operator presence control switch terminals on
the inside of the control console. Fasten the lead to the
handle with two large wire ties, from bolt bag, one at the
upper end of the handle next to the console and one at the
very lower end of the handle where it attaches to the fuel
tank support.
3.9 If the unit is shipped without the muffler attached, install
with hardware provided.

4. OPERATION INSTRUCTIONS
4.1 CONTROLS
4.1.1 Familiarize yourself with the controls and operation of the
unit.
Carefully read the following information about the controls
and their operation.
4.1.2 Drive Levers:
Located on each side of the upper handle assembly directly
below the handle grips. These levers individually control
clutching action of the wheel drive belts and brakes. When
the drive levers are all the way down, the wheel drive belts
engage and the brakes disengage. Squeezing the left or right
hand drive lever causes the left hand or right hand wheel to
slow down or stop, which makes the machine turn to the left
or right respectively. The sharpness of the turn varies by
how much the lever is squeezed. If both levers are squeezed
all the way back, both brakes will engage and the machine
will stop. For straight ahead motion, smoothly release both
drive levers to engage both drive wheels simultaneously.
4.1.3 Neutral Lock/Parking Brake Latches:
Located directly above the drive levers. The purpose of these
latches is to allow the operator to lock the drive levers in a
"neutral" position where neither the wheel drive belts nor the
brakes engage or in a “park brake” position where the wheel
drive belts are not engaged and the park brake is engaged. To
lock the drive levers in neutral, squeeze the drive levers back,
place thumbs on the upper portion of the neutral lock/park brake
latches and move them to the rear. Release drive levers. To
lock the drive levers in “park brake” position, squeeze the
drive levers back, place thumbs on the upper portion of the
neutral lock/park brake latches and move them ahead. Release
drive levers as stated in 4.1.2. (See Figure 12).
Apply parking brakes whenever leaving the operators position.
