SLOPE OPERATmON
%opes are a major factor reUatedto Uoss-of°controUand tip-
over accidents, which can resuUtin severe injury or death.
Operation on aHsUopesrequires extra caution. Ufyou cannot
back up the sUopeor if you feeUuneasy on it, do not operate
on it.
Control of a walk-behind or ride-on machine swing on a
slope will not be regained by the application of the brake.
The main reasons for loss of control are: insufficient tire
grip on the ground, speed too fast, inadequate braking, the
type of machine is unsuitable for its task, lack of awareness
incorrect hitching and load
distribution.
1. Mow up and down the face of slopes, not across.
2. Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Tall grass can hide obstacles.
3. Choose a slow speed so that you will not have to stop
or change speeds while on the slope.
4. Do not mow on wet grass. Tires may loose traction.
5. Avoid starting, stopping, or turning on a slope, if tires
lose traction (i.e. machine stops forward motion on a
slope), disengage the blade(s) (PTO) and drive slow
off the slope.
6. Keep all movement on slopes slow andgradual. Do
not make sudden changes in speed or direction,
which could cause the machine to rollover.
7. Use extra care while operating machines with grass
catchers or other attachments; they can affect the
stability of the unit. Do not use on steeps slopes.
8. Do not try to stabilize the machine by putting your
foot on the ground (ride-on units).
9. Do not mow near drop-offs, ditches, or
embankments. The mower could suddenly turn over if
a wheel is over the edge of a cliff or ditch, or if an
edge caves in.
10. Do not use grass catchers on steep slopes.
11. Do not mow slopes ifyou cannot back up them.
12. See your authorized dealer/retailer for
recommendations of wheel weights or
counterweights to improve stability.
13. Remove obstacles such as rocks, tree limbs, etc.
TOWED EQUmPMENT (RmDE-ON UNmTS)
1, Tow onUywith a machine that has a hitch designed for
towing, Do not attach towed equipment except at the
hitch point.
2. Follow the manufacturer s recommendations for
weight Hmitfor towed equipment and towing on
sUopes.See attaching a trailer under OPERATION.
3. Never allow children or others in or on towed
equipment.
4. On sbpes, the weight of the towed equipment may
cause Uossof traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. Do not shift to neutral and coast down hill.
WARNING
Never operate on slopes greater than 17.6 percent
(10 °) which is a rise of 3-1/2 feet (106 cm) vertically in
20 feet (607 cm) horizontally.
Select slow ground speed before driving onto slope.
Use extra caution when operating on slopes with rear-
mounted grass catchers.
Mow up and down the face of slopes, not across. Use
caution when changing directions and DO NOT
START OR STOP ON SLOPE.
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the unit
and the mowing activity. Never assume that children will
remain where you last saw them.
1. Keep children out of the mowing area and under the
watchful care of another responsible adult.
2. Be alert and turn unit off if children enter the area.
3. Before and during reverse operation, look behind and
down for small children.

DRiViNG PRACTICE-
BASIC DRIWNG
WARNING: Never operate on sUopesgreater than 17.6%
(10°). See SLOPE OPERATION in the safety section.
Zero turn riders operate differentUy from other four°
wheeUed vehicUes. The drive wheeUsare aUsoyour
steering wheeUs, ff you cannot drive the unit on a hill you
wHUnot be aMe to steer the unit on it. Operating zero
turn units on sUopesrequires extra caution.
The Uevercontrols of the zero turn rider are very
responsive, and Uearning to gain a smooth and efficient
controUof the rider's forward, reverse, and turning
movements wHUtake some practice.
Spend some time going through the foflowing maneuvers
and becoming familiar with how the unit accelerates,
travels, and steers -- before you begin mowing --is
absolutely essential to getting the most out of the zero
turn rider.
Locate a smooth, fiat area of your tawn -- one with
plenty of room to maneuver. (Clear the area of objects,
people and animals before you begin.) Operate the unit
at mid-throttle during this practice session (ALVVAYS
operate at full throttle when mowing), and turn slowly to
prevent tire slippage and damage to your lawn.
Smooth Trave_
The lever controls of the
zero turn rider are
highly responsive,
The BEST method of
speed control levers is in
three steps -- as shown
in Figure 4.
FIRST place your hands
onto the levers as
shown.
SECOND, to go forward
gradually push the levers
forward with your palms.
THIRD, to speed up
move the levers farther
forward. To slow down
smoothly, slowly move
the levers back toward
neutral.
Figure 4. Move Controt
Levers Gradually
We suggest you begin with the Smooth Travel procedure
to the right, and then advance through the forward,
reverse, and turning maneuvers.
WARNING
Do not mow in reverse. Always took down and
behind before and while travelling in reverse.
Forward Trave_
Forward Trave_ Practice
Gradually move both ground speed control levers evenly
FORWARD from neutral. Slow down and repeat.
Reverse Trave_ Practice
LOOK DOWN & BEHIND, then gradually move both
ground speed control levers evenly BACK from neutral.
Slow down and repeat.
NOTE: Practice backing up for several minutes before
attempting to do so near objects. The rider turns as
sharply in reverse as when going forward, and backing
up straight takes practice.
Reve rse Trave J
Figure 5. Forward Travet Figure 6. Reverse Travel
14
Practice Turning Around a Corner
Whib traveling forward allow one handb to gradually
return back toward neutral, Practice several times before
mowing,
NOTE: Toprevent damaging your lawn by pivoting
directly on the tire tread, it ie best to keep both wheele
going at least sfight/y forward.
Practice Turning mnP_ace
To "zero turn" means to turn in place, To turn in place,
gradually move one ground speed control lever forward
from neutral and one lever back from neutral
simultaneously, Repeat several times,
Executing Turns
Figure 7. RightTum Figure 8. Turning in Place
ADVANCED DRiViNG
Executing an End-Of-Row Zero Turn
Your zero turn rider's unique ability to turn in
place allows you to turn around at the end of a
cutting row rather than having to stop and make
a Yoturn before starting a new row,
For example, to execute a right end-of row zero
turn:
1, Slow down at the end of the row,
2, Move the LEFT ground speed control lever
forward slightly while moving the RIGHT
ground speed control lever back to center
and then slightly back from center, Be sure
to keep both wheels moving to prevent turf
damage,
3, Begin mowing forward again,
This technique turns the rider RIGHT and
slightly overlaps the row just cut --eliminating
the need to back up and re-cut missed grass,
As you become more familiar and experienced
with operating the zero turn rider, you wifl learn
more maneuvers that will make your mowing
time easier and more enjoyable.
Remember, the more you practice, the better
your control of the rider wilt be!

when the gauge is inserted and removed, and make
any necessary adjustments by tightening or
loosening the adjustment nuts.
NOTE: The actual air gap between the rotor and
armature may vary even after performing the adjustment
procedure. This is due to dimensional variations on
component parts, and is an acceptable condition.
6. Check the mower blade stopping time. The mower
blades and mower drive belt should come to a
complete stop within five seconds after the electric
