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 the 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.
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

•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.
How to Change the Speed/Sensitivity
Adjustment
The controls are initially set with the Speed/ Sensitivity
adjustment in the slower,
less sensitive position. This
setting has the ground
speed 10-15% slower than
the mowers capability.
With operators not
completely familiar with the
mower operation the operator may desire to leave the
controls in the slow hole setting until becoming familiar
with the operation. The faster setting has a
corresponding increase in the sensitivity of the controls.
In other words, a given amount of movement of the
control levers will cause about a 10-15% increase in the
ground speed making the controls more sensitive. After
stopping the engine, the adjustment is made by
removing rod ends connected to the control rods from the
current holes in the control levers and reinstalling them
into the alternate holes. The holes closest to the
operators position are for the faster, more sensitive
setting and the holes farthest from the operators position
are the slower, less sensitive setting. You must then
perform the Tracking Adjustment described below.
How to Perform the Tracking Adjustment
First ensure that the tire pressure is equal on both
rear drive tires. Drive the mower on a level parking
lot with engine at full throttle. Check that the mower
drives in a straight line when both hand controls are
held to the full speed position which is up against the
stationary control bar. If not, park the mower and
stop the engine. Before proceeding to adjusting
the mower tracking, check and make sure both
controls move freely through the forward and
reverse range. Make sure that debris has not
hindered the movement of the upper and lower
control rods and linkages. If all control linkages
move freely and mower tracking is off, proceed to
the next step.
Tracking in the Slow Hole Setting
It is essential to start with the lower (and shorter)
control rods located near the pumps. With the
control levers in the neutral position, the right and
left lower control rod should be adjusted to allow
their respective torsion bar to remain level at the end
connected to the lower control rod. Specifically, with
