Thank you for buying a SNAPPER product! Before operating the Lawn Tractor, read and follow the
“IMPORTANT SAFETY INSTRUCTIONS” on pages 2 & 3, all other instructions contained in this manual and the
accompanying booklet “About Power Mower Safety”. Lawn mowers and all power equipment can be potentially
dangerous if used improperly. REMEMBER: SAFETY REQUIRES CAREFULL USE IN ACCORDANCE WITH
INSTRUCTIONS AND COMMON SENSE!
WARNING: This powerful cutting machine is capable of amputating hands and feet and can throw objects that
can cause injury and damage! Failure to comply with the following SAFETY instructions could result in serious
injury or death to the operator or other persons. The owner of the machine must understand these instructions
and must allow only persons who understand these instructions to operate machine. Each person operating the
machine must be of sound mind and body and must not be under the influence of any substance, which might
impair vision, dexterity or judgment. If you have any questions pertaining to your machine which your dealer
cannot answer to your satisfaction, call or write the Customer Service Department at SNAPPER, McDonough,
Georgia 30253. Phone: (1-800-935-2967).
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 or on attachments (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 super vision 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 AGAINST TIPOVERS
Slopes are a major factor related to loss-of-control
and tip-over accidents, which can result in severe
injury 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 15
degrees (27% grade).
2. Exercise EXTREME CAUTION on slopes above 10
degrees (18% grade). Turn blades OFF when
traveling uphill. Use a slow speed and avoid
sudden or sharp turns.
3. DO NOT operate machine back and forth across
face of slopes. Operate up and down. Practice on
slopes with blades off.
4. AVOID uphill starts. If machine stops going uphill
or tires lose traction, turn blades OFF and back
slowly down the slope.
PROTECTION AGAINST TIPOVERS
(Continued From Previous Column)
5. STAY ALERT for holes and other hidden hazards.
Tall grass can hide obstacles. Keep away from
ditches, washouts, culverts, fences and
protruding objects.
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 and with
caution.
8. Use weights or a weighted 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. DO NOT operate machine under any condition
where traction, steering or stability is doubtful.
PREPARATION

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 instruction.
3. Data indicates that operators age 60 and above,
are involved in a large percentage of mowerrelated 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 mowed and remove all
objects such as toys, wire, rocks, limbs and other
objects that could cause injury if thrown by blade
or interfere with mowing.

4.2.1. BLADE BRAKE ADJUSTMENT
The blade brake when properly adjusted will stop
blade rotation in 5 seconds or less when the blade
engagement lever is moved to the OFF position.
33” DECK BLADE BRA KE A DJUS TMENT
1. Blade brake adjustment is made by turning the
adjustment nut on the thr eaded brake rod. The brak e
is initially set with 1-3/16” of thread exposed beyond
the nut. See Figure 4.1. Verify this setting before
attempting any adjustments. To tighten the brake
(stop blade rotation quicker) turn the adjustment nut
clockwise – ONE TURN ONLY.
IMPORTANT: DO NOT over-tighten blade brake.
Tighten one turn and check f unction of brak e. If blade
stop time remains over 5 seconds, turn adjustment
nut 1 to 2 turns clockwise. If blade stop tim e remains
over 5 seconds, DO NOT OPERATE machine.
Contact your SNAPPER dealer for assistance.
WARNING
DO NOT operate machine unt il blade brake has been
repaired and functioning properly. If blade stop time
can not be achieved with the adjustment procedure
described above, take machine immediately to an
authorized SNAPPER dealer.

DO NOT use “BOOST” chargers on the battery.
4.5.5. BATTERY TESTING
There are two types of battery tests: Unloaded and
Loaded. The unloaded test is the procedure that will
be discussed. It’s the simplest and most commonly
used. An unloaded test is m ade 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.
4.5.6 NEW BATTERY PREPARA TION
1. Remove battery from carton.
2. Place battery in a well ventilated area on a level non-
concrete surface.
3. Remove battery cell caps. Fill cells as required
with electrolyte (purchased separately) to proper level.
Fill to 3/16” above cell plates. Filling battery with
electrolyte will bring the battery to 80% charged state.
4.5.7. BATTERY TESTING
4. With cell caps rem oved, connect battery charger to
battery terminals; RED to positive (+) and BLACK to
negative (-) terminal.
IMPORTANT: 3/16” above cell plates is the recommended
level. DO NOT place anything in battery other than specified
electrolyte.
5. Slow charge the battery at 1 amp for 2 hours to
bring the battery to full charge.
6. After charging, check level of electrolyte and add
as needed to bring level to 3/16” above cell plates.
7. Reinstall cell caps.
8. Slide battery partially into battery housing.
9. Connect positive (+) cable (red) first, from wiring
harness to the positive terminal ( +) on battery using bolt
and nut provided in hardware bag. Connect negative (-)
cable (black) last, to negative terminal (-) on battery
using bolt and nut. Apply a small am ount of gr eas e over
terminals to prevent corrosion.
10. Insert battery completely into battery housing.
11. Reinstall seat assembly.
Shield the positive terminal with terminal cover
located on battery harness. This preven ts metal from
touching the positive terminal, which could cause
sparks. Cables must be connected to battery
terminals in the proper position. RED (Positive) cable
must go to the ( + ) terminal. BLACK (Negative) cable
must go to the ( - ) terminal.
