PROTECTION FOR CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
machine 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 a responsible adult.
2. DO NOT allow children in yard when machine is
operated (even with the blade OFF).
3. DO NOT allow children or others to ride on machine,
attachments, or towed equipment (even with the
blades OFF). They may fall and be seriously injured.
4. DO NOT allow pre-teenage children to operate
machine.
5. ALLOW only responsible adults & teenagers with
mature judgment under close adult supervision to
operate machine.
6. DO NOT operate blades in reverse. STOP BLADES.
LOOK and SEE behind and down for children, pets
and hazards before and while backing.
7. USE EXTRA CARE when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.
PROTECTION AGA INST TIPOVERS
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe inju ry or death.
All slopes require extra CAUTION. If you cannot back up
the slope or if you feel uneasy on the slope, DO NOT mow
it. Use extra care with grass catchers or other attachments;
these affect the handling and the stability of the machine.
1. DO NOT operate machine on slopes exceeding 10
degrees (18% grade).
2. Exercise EXTREME CAUTION on ALL slopes. Turn
blades OFF when traveling uphill. Use a slow speed
and avoid sudden or sharp turns.
3. DO NOT operate machin e back and forth across face
of slopes. Operate up and down. Practice on slopes
with blades off.
4. AVOID starting, stopping and turning on slopes. If
machine stops going uphill or tires lose traction, turn
blades OFF and back slowly straight down the slope.
5. STAY ALERT for holes and other hidden hazards. Tall
grass can hide obstacles. Keep away from ditches,
washouts, culverts, fences and protruding objects.
PROTECTION AGA INST TIPOVERS
(Continued From Previous Column)
6. KEEP A SAFE DISTANCE (at least 3 feet) away from
edge of ditches and other drop offs. The machine
could turn over if an edge caves in.
7. Always begin forward motion slowly a nd with caution.
8. Use weights or a w eighted load carrier in accordance
with instructions supplied with a grass catcher. DO
NOT operate machine on slopes exceeding 10 degrees
(18% grade) when equipped with grass catcher.
9. DO NOT put your foot on the ground to try to stabilize
the machine.
10. DO NOT operate machine on wet grass. Reduced
traction could cause sliding.
11. Chose a low enough ground speed setting so that you
will not have to stop or shift on a slope. Tires may lose
traction on slopes even though the brakes are
functioning properly.
12. DO NOT operate machine under any condition where
traction, steering or stability is doubtful.
13. Always keep the machine in gear when going down
slopes. DO NOT shift to neutral (or actuate the hydro
roll release) and coast downhill.

1. Read, understand, and follow instructions and
warnings in this manual and on the machine, engine
and attachments. Know the controls and the proper
use of the machine before starting.
2. Only mature, responsible persons shall operate the
machine and only after proper instr uction.
3. Data indicates that operators age 60 and above, are
involved in a large percentage of mower-related
injuries. These operators should evaluate their ability
to operate the mower safely enough to protect
themselves and others from serious injury.
4. Handle fuel with extra care. Fuels are flammable and
vapors are explosive. Use only an approved fuel
container. DO NOT remove fuel cap or add fuel with
engine running. Add fuel outdoors only with engine
stopped and cool. Clean spilled fuel from machine. DO
NOT smoke.
5. Practice operation of machine with BLADES OFF to
learn controls and develop skills.
6. Check the area to be mo wed and remove all objects
such as toys, wire, rocks, limbs an d ot her o bject s t hat
could cause injury if thrown by blade or interfere with
mowing.

2.6 REVERSE LOCKOUT MECHANISM
Data indicates that tragic back-over accidents occur
each year. These accidents usually involve
unsupervised children. Many times these childr en have
been given rides on the mac hine and have been trained
to view this potentially dangerous piece of m achinery as
fun rather than being taught how to avoid danger.
This riding mower has a Rever se Lockout Mechanism.
This mechanis m prevents the mower fr om being shifted
into reverse with the blade running. To shift into reverse
you must first stop the blade by releasing the blade
pedals and then shift to reverse. It is our
recommendation that this mechanism remains
functional and the operator of this equipm ent develops
the habit of never backing up with the blade running. As
the Safety Instructions Indicate, DO NOT operate
blades in reverse. STOP BLADES, LOOK AND SEE
BEHIND AND DOWN for children, pets and hazards
before and while backing.
We realize that this could cause a change to your
previous mowing method but we encourage you to
adjust to this new system. Do not defeat the Reverse
Lockout Mechanism.
If you operate your mower near roadways or use
attachments that require quicker shifting to reverse,
there is an override lever provided. This lever can be
pushed and held before starting the blade and will allow
reverse operation until the blade pedals are released, at

4.6.6. BATTERY TESTING
There are two types of battery tests: Unloaded and
Loaded. The unloaded test is the proc edur e that will
be discussed. It’s the sim plest and most comm only
used. An unloaded test is made on a battery without
discharging current. To perform unloaded testing,
check charge condition using either a hydrometer or
voltmeter.
1. Using a voltmeter, voltage readings appear
instantly to show the state of charge. Remember to
hook the positive lead to the battery’s positive
terminal, and the negative lead to the negative
terminal.
2. A hydrometer measures the specific gravity of
each cell. The specific gravity tells the degree of
charge; generally, a specific gravity of about 1.265
to 1.280 indicates full charge. A reading of 1.230 to
1.260 indicates the battery should be charged. The
chart on the next page shows the charge level as
measured by syringe float hydrometer, digital
voltmeter and five ball hydrometer.
