A.General
1. When Mowing:
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 levers when starting 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. Watch for 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 turning 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 downhill side of the machine...I.E.,
Engine throttle
Choke Lever
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. Never leave the mower unattended without
observing the following: turn off the blade clutch switch, placing the steering levers in 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).
8
b. Avoid 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
mower toward streets, buildings, play-
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 turning and come to a
complete stop before any zero turn 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 Pat­tern
a. Pick a point on the opposite side of the
area to be mowed (post, tree, shrub, etc.).
b. If on an hillside, start 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. Remember, 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 of the seat in the center support. When the key is inserted and turned clockwise, 45 degrees, the ignition circuit is closed. Turning the switch further against spring pressure starts the engine. The engine will only start if the blade clutch switch is in the “off” position, the park­ing brake is engaged and the left and right steering levers are in the neutral. The key should always be removed from the switch if the operator leaves the mower’s seat.
2. Engine Throttle Control: (See Figure 2.) Located on the left side of the seat support. Moving the throttle control from the rear to the front will increase the engine speed from slow to fast.
3. Left and Right Steering Levers: (See Figure
3.) These levers control all of the movements of the mower. Pushing both levers forward causes the mower to move forward. Pulling both levers back causes the mower to move backward. Pushing one lever ahead of the other lever causes the traction wheel on the side where the lever is ahead to rotate faster than the other traction wheel, making the mower turn toward the side where the lever is behind. When one lever is pushed forward and the other lever pulled back the same amount, one traction wheel will turn in reverse and the mower will turn within its own length.
In order to start the engine, both steering levers must be in the neutral position; the parking brake must be engaged; and the blade clutch switch must be “off”. However, once the engine starts, the parking brake must be released before the operator moves the steering levers out of neutral position or the engine will automatically shut off.
Note:
neutral when released, but they should be placed in neutral by the driver. If the Drive Handles are not placed in neutral, the tractor may creep.
The Steering Lever will return toward

4. Electric Blade Clutch Switch: (See Figure
1.) Located on the seat support beside the ignition switch. This is an “on/off” push pull switch that controls the electric blade clutch which supplies power to the cutting blades through the PTO. The switch must be turned off to start the engine and should be turned off for safety any time another person approaches the mower or the mowing deck is raised to the transport position. Power to the electric clutch will also be cut off if the opera­tor leaves the operator’s seat.
5. Parking Brake: (See Figure 3.) Located on the left side of the traction unit. The handle is an overcenter lever which applies the drum­type brake on each drive wheel when the han­dle is pulled to the rear. The brake must be engaged in order to start the engine.
6. Deck Lift Handle: (See Figure 3.) Located on the right front corner of the 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 deck, pull the deck lift han­dle and move it outward. This lower’s the deck to the cutting position.
7. Fuel Shutoff Valve: (See Figure 4.) Located on top of the fuel tank(s). When turned in a clockwise direction until it stops, it will shut off the flow of fuel to the engine. When turned in a counterclockwise direction it will open and allow fuel to flow to the engine. Close this valve if you are not going to run the mower for a period of 30 minutes or more to prevent flooding the engine.
8. Seat Adjustment Lever: The Seat Adjust­ment Lever is located beneath the seat. The Seat Adjustment Lever is used to move the seat forward 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.

Fuel Shutoff Valve
9. Digital Tachometer and Hour Meter: (See Figure 1) Located on the seat support above the ignition switch. When the machine is run­ning the tachometer displays engine rpm. When the machine is off the tachometer dis­plays running time.
Note:
each recommended lubrication interval. There is a flashing “OIL” at each recommended engine oil and filter change.
There will be a flashing “LUBE” for
10. Choke Lever: (See Figure 2) The Choke Lever is located on the left side of the seat support. The Choke Lever is operated manu­ally. Having the Choke Lever in the ON posi­tion helps the engine to start during initial start-up. During normal operation the Choke Lever should be in the OFF position.
11. Folding Deck Control: The switch for the electrically powered deck folding mechanism is located on the seat support. Pull upward on the switch to fold up, and push downward to fold down.
