4. OPERATION INSTRUCTIONS
4.1 Controls
4.1.1Drive Levers: Located on each side of the upper handle assembly directly
below the handle grips (See Figure 4). T hese levers individually control the
speed and direction of each drive wheel. When the speed control lever is
moved out of the neutral position and the neut ral lock latches are moved into
the drive position, as shown in Figure 4, and the drive levers are released, t he
drive wheels are engaged in the forward direction.
Squeezing the left hand and/or r ight hand lever causes the left hand and/or
right hand drive wheel respectively to slow down, stop, or reverse, depending
on how far each drive lever is "squeezed". Squeezing the drive levers beyond
the neutral position causes the drive wheels to engage in the re verse dir ect ion
regardless of the position of the neutral lock latches and the speed control
lever.
4.1.2Neutral Lock Latch: Located directly above the drive levers. These latches
allow the operator to lock the drive levers in a "neutr al" posit ion where neither
of the drive wheels are engaged in either a forward or reverse direction. See
Figure 4.

POTENTIAL HAZARD
♦ In certain conditions gasoline is extremely flamm able and
highly explosive.
WHAT CAN HAPPEN
♦ A fire or explosion from gasoline can bur n you, ot hers,
and cause property damage.
HOW TO AVOID THE HAZARD
♦DO NOT smoke while refueling , and stay away from an
open flame or where gasoline fumes m ay be ignited by
spark.
♦ Refuel only in a well ventilated area, or refuel outdoor s.
♦ Store gasoline in an approved container and keep it out of
the reach of children.
♦ Add fuel before start ing 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 gasoline level rises
above a level that is 1/2” below the bottom of the filler

position. Check to see if the wheel stops. I f not, repeat the above
adjustment procedure.
6. Make this adjustment on both sides.
7. After adjustments ar e m ade and the wheels stop when the drive lever
is in the neutral position, tighten the nut against the yoke.
c)Adjust Hydro Cont rol Linkage:
1. Place the speed control lever in the “neutral” position. This adjustment
is again made with rear of machine on jack st ands and engine
running at full thr ot tle. OPC levers will have to be held down
whenever speed control lever is moved out of neutral position.
2. Loosen the front nut on
left
hydro control link as shown in Figure 9.
Turn the rear control link age adjusting nut counter-clockwise until
wheel rotates forward. Turn the r ear nut of left control link clockwise
1/4 of a turn at a time, stopping to move the speed control forward
and back to neutral, until left wheel stops rotating forward. Turn the
nut an additional 1/2 turn and tighten the front jam nut making sur e
not to put a bind on the linkage. Make sur e flat part of linkag e is
perpendicular to pin part of swivel. See Fig. 10.

After adjusting t he left hydro control linkage, move the speed control lever to
the mid-speed position and then back to the neut ral position. Recheck the left
drive wheel rotation to see if further adjustment is necessary - be sure the
speed control lever is in the neutral position.
If inconsistent neutral occurs, check to be sure both springs are properly
tightened on the speed control lever under the console - especi ally the
rear pivot spring.
Repeat above adjustments if necessary.
3. Place the speed control lever in neutral. Adjust the rig ht side linkage
by turning the quick track knob counter-clockwise until the tire beg ins
to rotate forward. Begin t o r etighten the knob clockwise about 1/4
turn at a time, stopping to m ove the speed cont r ol forward and back
to neutral. Recheck the drive wheel rotation to see if further
adjustment is necessary.
4. The spring that keeps tension on the k nob should nor m ally not need
adjustment. However, if adjustm ent is needed, adjust to where length
of spring is about 1” between washers. Adjust spring length by
turning nut at fr ont of spring.
d)Drive Lever Linkage Adjustment
1. With rear of machine still on jack stands and engine running at full
throttle, move the speed control lever to t he m idway position. Move
the respective drive lever upward until it reaches the
neutral
position
and engage neutral lock latches. See fig. 11. If the t ir e r otates in
either direction, the lengt h of the drive lever linkage will need to be
adjusted.
DRIVE LEVER AND LATCH IN NEUTRAL POSITION
2. Adjust the linkage length by releasing the drive lever and removing
clevis pin and rotating the linkage in t he lower swivel. Lengthen t he
linkage if the tir e is turning in reverse and shorten the linkage if the
tire is creeping forward. Rot ate the linkage several turns if t he tire is
rotating fairly fast. But as the adjustment gets closer, adjust the
linkage in 1/2 turn increment s. Release and re-engage neutral lock
latch checking that the tire st ops. Continue these process until the
tire is at a dead stop.
3. Replace the hairpin back into each clevis pin.
4. Make this adjustment for both sides.
e) T r acking Adjustment
1. Stop engine, raise rear of machine, r e m ove jack stands and carefully
lower machine to the ground.
2. Check the drive tire pressures and tire circumf er ences. See 5.1.11.
3. Run the unit and observe the tracking on a level, smoot h, hard
surface such as concrete or asphalt.

4. If the unit tracks to one side or t he other, turn the quick track knob.
Turn the knob right to “steer” right, tur n t he knob left to “steer” left.
5.2.6Hydro Pump Spring Tension Setting
a)For medium or heavy duty drive conditions such as operation with a sulky
on steep slopes, a higher spring f or ce may be required on the hydro
pump control arms to prevent the drive system from stalling.
b)For a heavier drive setting, relocate the spring anchor link as shown in
Figure 12. The spring anchor links are located under the engine deck on
the left and right hand sides.
Note:
upper handle will also be increased.
5.2.7Throttle Control Adjustm ent
a)Loosen cable clamp on engine and position throttle control (at t he control
console) within 1/8" from the upper end of the slot. Pull on cable
assembly at lower end where it attaches to the engine until the throttle
control arm contacts the stop screw. Secure cable with cable clamp.
b)Tension in throttle lever can be adjusted by adjusting the tightness of the
lever pivot bolt, which is located under the console.
5.2.8Electric Clutch Adjustment
No adjustment necessary.
In “medium” or “heavy duty” positions, the drive lever f o r ces at the

HYDRO PUMP SPRING TENSION SETTING
6. TROUBLE SHOOTING
6.1 MOWER TRACKS TO LEFT OR RIGHT.
a)Check the drive tire pressures and tire circumferences. See 5.1.11.
b)Turn knob on the right hydro contro l linkage in the direction that the
mower needs to be adjusted to. Turn the knob in 1/4 turn increments
until the mower tracks correctly.
6.2 MOWER CUTS UNEVENLY.
a)Check the drive tire pressures and tire circumferences. See 5.1.11.
A more uniform cutting height may be obtained with higher tire pressure
on rough terrain. A lower tire pressure provides more flotation.
b)Check deck support pins. Hairpin clips must be in t he sam e hole posit ion
on each support pin.
c)Check deck support alignment and check mounting brackets to be sure
all bolts are tight.
d)Check blades tip to tip for straig ht ness. (They should be within 3/16”, or
one blade width from being in line.)
6.3 ENGINE WILL NOT START.
a)Check that the throttle control is m idway between “slow” and “fast”
positions, and choke is in “on” position f o r a cold engine or “off” position
for a warm engine.

b)Make sure the speed control lever is in the “true neutral” position. (See
Section 5.2.5)
c)Check t hat the blades are disengaged.
d)Make sure the "OPC" levers are depressed.
e)Check that there is fuel in the t ank and that the fuel valve is open.
f)Check that the spark plug wires are properly connected.
g)Check for loose or faulty wiring connections. If it is necessary to
disconnect wire connectors, Do Not pull on the wires.
h)Check for corrosion at all wiring connections. Even minor corr o sion m ay
cause a faulty connection. Clean connector terminals t hor oughly, apply
dielectric grease and reconnect.
IMPORTANT: It is essential that all operator safety mechanisms be
connected and in proper operating condition prior to mower use.
NOTE:
After carefully checking the above steps, attempt to start the eng ine. If
it does not start, contact your author ized Exmark service dealer.
