4.2 SAFETY INTERLOCK SYSTEM
The mower is equipped with a safety interlock system
that prevents the engine from starting unless the deck
drive is disengaged, the parking brake is engaged and the
speed control lever is in the neutral position. With the
use of "Sensogrip Technology", the interlock system shuts
off the engine if the operator removes both hands from the
steering control with the speed control not in the neutral
position, the cutter blades engaged and/or the parking
brake not engaged.
-IMPORTANT-
The grips on the steering control handle sense
the presence of the operators hand using
"Sensogrip Technology". When using thick
gloves, more hand contact to the steering control
handle may be required.
4.3 INITIAL RUN-IN PROCEDURES (First

obstructions. Practice until you are comfortable
with the handling of the machine before
attempting to mow. Learn the operation on flat
ground before operating on slopes.
-IMPORTANT-
Start practicing with a slow engine speed and
slow forward travel.
Learn to feather the steering controls to obtain a
smooth operating action.
Practice operating the mower until you are
comfortable with the controls before proceeding
to mow.
Forward Travel
To travel forward with the mower, place one hand on the
steering control, disengage the parking brake and push
down and forward on the speed control lever to set the
desired speed. Once the desired forward speed is selected
with the speed control lever, slowly push downward on
the steering control to start forward movement. The
further the speed control lever is moved forward and the
steering control is pushed downward, the greater the
forward speed will be. To decrease the speed, pull
upward on the steering control or pull back on the speed
control lever to set the desired speed. See Figure 4-2.
To stop the forward travel completely, pull the speed
control lever back to the neutral position.
To steer the mower to the left while traveling forward,
move the steering control to the right. The further the
steering control is moved, the quicker the mower will turn
left. See Figure 4-3.
To steer the mower to the right while traveling forward,
move the steering control to the left. The further the
steering control is moved, the quicker the mower will turn
right. See Figure 4-3.
-NOTE-
Smooth operation of the steering control lever
will produce smooth mower operation. While
learning the operation of the steering controls,
keep the travel speed low.
Reverse Travel
To travel in reverse, pull upward on the steering control.
Keep the travel speed low while traveling in reverse.
-NOTE-
The mower may not travel straight in reverse.
Slight adjustments may need to be made using
the steering controls.
To steer left while traveling in reverse, move the steering
control to the left. The further the control is moved, the
quicker the mower will turn left.
To steer right while traveling in reverse, move the steering
control to the right. The further the control is moved, the
quicker the mower will turn right.
To stop the reverse travel, allow the steering control to
return to the neutral position. If the mower is to be
parked, engage the parking brake.

4.6 ENGAGINGTHE DECK DRIVE (CUTTER
BLADES)
1. Set the throttle at about 3/4 speed. Do not attempt to
engage the deck drive at high speed as this shortens
the electric clutch life — use only moderate engine
speed when engaging the deck drive.
2. Engage the deck drive by pulling out on the yellow
switch, located on the instrument panel, (Figure 4-4)
to the engage position.
-NOTE-
A squealing noise may be heard when engaging
or disengaging the deck drive. It is caused by
the electric clutch plates meshing as the mower
comes up to speed. This is normal.
3. To disengage the deck drive, push the switch in to the
disengageposition.
4. Always operate the engine at full throttle to properly
maintain cutting speed. If the engine starts to lug
down, reduce the forward speed and allow the
engine to operate at maximum RPM.
Figure 4-3 Steering Controls
Before backing up, observe behind the mower for
persons and obstructions. Clear the area before
backing up. Possible injury or property damage
could occur.

Section 4
4.7 HILLSIDE OPERATION
1. This mower has been designed for good traction and
stability under normal mowing conditions. However,
caution must be used when traveling on slopes,
especially when the grass is wet. Wet grass reduces
traction and steering control.
2. To prevent tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel at
reduced speed. If tires lose traction, disengage blades
and proceed slowly off the slope.
3. Always travel across a slope with a walk behind
mower.
4. Keep tires properly inflated.
4.8 PARKINGTHE MOWER
1. Park the machine on a flat, level surface only. Do
not park the machine on an incline.
2. Place the steering control levers in the neutral
position.
3. Disengage the cutter blades
4. Slow the engine to idle speed.
5. Engage the parking brake.
6. Turn the ignition key to the OFF position and remove
the key.
4.9 AFTER OPERATION
1. Wash the entire mower after each use. Do not use
high pressure spray or direct the spray onto electrical
components.
-IMPORTANT-
Do not wash a hot or running engine. Cold water
will damage the engine. Use compressed air to
clean the engine if it is hot.
2. Keep the entire mower clean to inhibit serious heat
damage to the engine or hydraulic oil circuit.
3. Check the drive belts for proper alignment and any
signs of wear. Correct and adjust if necessary.
4. After the mower has cooled down, fill the fuel tank
with fresh, clean fuel at the end of every day of
operation.
5. Check the tire pressure. Adjust pressure if necessary.
4.10 REMOVING CLOGGED MATERIAL
To avoid injury from burns, allow the mower to
cool before removing the fuel tank cap and
refueling.
CAUTION:
1. If the discharge chute becomes clogged, shut off the
engine and remove the ignition key. Using a stick or
similaritem, dislodge the clogged material. Then
resumenormal mowing.
NEVER PUTYOUR HANDS INTOTHE CHUTE
AREA. Remove the key and only then use a stick
or similar object to remove material if clogging
has occurred.

WARNING:
4.13 ADJUSTING CUTTING HEIGHT
The mower deck can be adjusted from a height of 1-inch
to 4-1/2 inches at 1/4-inch intervals. To adjust the cutting
height:
8. Use the alternate stripe pattern for best lawn
appearance. Vary the direction of the stripe each
time the grass is mowed to avoid wear patterns in
the grass.
WARNING
WARNING
DO NOT OPERATE WITHOUT DISCHARGE CHUTE, MULCHING
KIT, OR ENTIRE GRASS CATCHER INSTALLED
4.11 MOVING MOWER WITH ENGINE
STOPPED
To “free-wheel” or move the mower around without the
engine running, place the dump valve levers in the FREE-
WHEEL position. Disengage the parking brake and move
the mower by hand. The dump valve levers must be
returned to the DRIVE position and torqued to 7-10 ft/lbs
to drive the mower.
4.12 RECOMMENDATIONS FOR MOWING
1. Do not mow with dull blades. Adull blade will tear
grass, resulting in poor lawn appearance and require
extra power.
2. The discharge chute must not be removed and must
be kept in the lowest position to deflect grass clippings
and thrown objects downward. Direct the side
discharge away from sidewalks or streets to minimize
cleanup of clippings. When mowing close to
obstacles, direct the discharge away from the
obstacles to reduce the chance of property damage by
thrown objects.
3. Cut grass when it is dry and not too tall. Do not cut
grass too short (cut off 1/3 or less of existing grass for
best appearance). Mow frequently.
4. Keep mower and discharge chute clean.
5. When mowing wet or tall grass, mow the grass twice.
Raise the mower to the highest setting for the first
pass and then make a second pass to the desired
height.
6. Use a slow travel speed for trimming purposes.
7. Operate the engine at full throttle for best cutting.
Mowing with a lower RPM causes the cutter blades
to tear the grass. The engine is designed to be
operated at full speed.
