levers, one at a time, very slightly, forward and
backward. Gradually increase your speed until
you are well acquainted with the operation of
the hand controls and the mower’s behavior.
After gaining a good feel for how the mower
handles, gradually attempt higher engine
speeds until familiar with operation at full
throttle engine speed.
How to Stop and Park the Mower
Come to a complete stop. If the blades are on,
turn them off using the switch on the instrument
panel. Make sure the control levers are in the
exact neutral position. Set the parking brake,
reduce the engine speed to idle, shut off the
ignition switch to stop the engine and then
remove the key from the ignition switch. The
mower is now parked. Do not leave mower
unattended on a sloped surface.
How to Drive the Mower Over a Curb
To climb a curb, first see the Safety Instruction
Manual section of this manual, especially the
parts on:
• Initial Operating Safety Guidelines
• Operation In Reverse
• Operation In Forward Direction
Next, raise the mower deck into the locked
transport position. This is the highest position
for the mower deck. Then drive the mower in
reverse at a 45 degree angle to the curb (with
the left side of the mower closest to the curb)
until you are within an inch or two of the left-
rear tire hitting the curb. Stop and then
gradually bump into the curb with that tire until it
is just on top of the curb. If the tire slips even
while lurching the mower into the curb, then the
curb is too high and you should use ramps or
find another way. The mower should still be at
a 45 degree angle to the curb. Now, while
maintaining the same angle to the curb,
continue to back up until the right-rear tire is
close to the curb. Using the same technique
lurch the right tire onto the curb. After both
wheels are on top of the curb, turn the mower
counterclockwise and back up so the left caster
wheel comes over and last should be he right
caster wheel as the mower is twisting to the left
(counterclockwise). The technique works the
best if you try not to drive backwards at a near
90 degree angle to the curb but get all of the
wheels to go over while the mower is moving at
least a 45 degree angle to the curb. To drive
off a curb, first try driving up onto it to make
sure the curb is not too high. If the curb is not
too high, drive the right-front caster off first
while driving toward the curb at a 45 degree
angle (the curb should be to your right). Then,
maintain that 45 degree angle so the left caster
goes over, then the right-rear wheel, then the
left rear wheel.
WARNING
Never drive straight onto or off a curb.
Never drive straight onto or off a curb. If you do
the whole procedure at a very sharp angle it will
tend to minimize the contact of the mower deck
with the curb and you will be able to more
safely control the mower.
How to Use the Mower on Varying
Terrain
See the Safety Instruction Manual section of
this manual, especially the parts on:
• Initial Operating Safety Guidelines
• Operation On Slopes
• Operation In Reverse
• Operation In Forward Direction
• Operation During Zero-Radius Turns
How to Adjust Neutral
Neutral refers to the mower movement when
the engine is set to full throttle, parking brake is
off, and the control levers are in the neutral
position. The mower should not move forward
or backward during this time. If the mower is
moving forward or rearward, the neutral setting
must be adjusted. The hydraulic pump has a
Return-to-Neutral (RTN) device built into the
linkage of the pump. To make the adjustment,
loosen the ¼” allen bolt and rotate the RTN
device until the neutral position is found and
then retighten the ¼” allen bolt. Use care not to
over tighten the allen bolt.
