2.6 REVERSE LOCKOUT MECHANISM
2.6.1. Reverse Lockout Mechanism Override
1. Stop machine. Stop blade.
Data indicates that tragic back-over accidents occur
each year. These accidents usually involve
unsupervised children. Many times these children have
been given rides on the machine and have been trained
to view this potentially dangerous piece of machinery
as fun rather than being taught how to avoid danger.
2. Depress and hold Override Lever.
3. Depress and hold Blade Pedals. Release
Override Lever.
4. Move blade lever forward to “ON” position.
WARNING
This riding mower has a Reverse Lockout Mechanism.
This mechanism prevents the mower from 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 equipment 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.
LOOK and SEE behind and down for children, pets
and hazards before and while backing.
IMPORTANT: DO NOT use the Reverse Lockout
Mechanism Override as the normal operating mode. To
return to the Reverse Lockout Mechanism mode,
release blade pedals to turn blade off. The Override will
reset to Reverse Lockout. Check the Reverse Lockout
Mechanism frequently for proper function. With the
blade pedals depressed, the shift lever must not go into
reverse. DO NOT operate machine if Reverse Lockout
Mechanism is not functioning properly. Contact your
local Snapper dealer for assistance.
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 which time the system will return to its Reverse
Lockout mode. This feature should never be selected
unless you are absolutely sure that no children or
others are present in the mowing area and that all
children are away and supervised by a responsible
adult.
DANGER
LOOK and SEE behind and down for children, pets
and hazards before and while backing.
BLADES must be turned off before backing
machine.
DO NOT allow children on machine (even with
blades off) or in yard when mowing.

WARNING
WARNING
The electrolyte (acid) produces a highly explosive gas.
Keep all sparks, flame and fire away from area when
charging battery or when handling electrolyte or
battery. Electrolyte (acid) is a highly corrosive liquid.
Wear eye protection. Wash affected areas immediately
after having eye or skin contact with electrolyte (acid).
Battery acid is corrosive. Rinse empty acid containers
with water and mutilate before discarding. If acid is
spilled on battery, bench, or clothing, etc., Flush with
clear water and neutralize with baking soda.
DO NOT attempt to charge battery while installed on
the Riding Mower. DO NOT use “BOOST” chargers on
the battery. DO NOT OVERFILL!
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 to proper level.
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 amount
of grease over terminals to prevent corrosion.
10. Insert battery completely into battery housing.
11. Reinstall battery cover. See Figure 4.16.
4.6.3. BATTERY SERVICE
1. Remove battery. See Section on Battery Removal.
2. Place battery in a well ventilated area on a level
surface.
3. Using distilled water, refill cells as required to
cover cell plates of which can also be visualized
through the plastic battery case.
4. With cell caps removed, connect battery charger
to battery terminals. Red to positive (+) terminal
and black to negative (-) terminal.
5. Slow charge battery at 1 amp for 10 hours.
6. If battery will not accept charge or is partially
charged after 10 hours of charging at 1 amp,
replace with new battery.
WARNING
Shield the positive terminal with terminal cover
located on battery harness. This prevents metal from
touching the positive terminal, which could cause
sparks.
4.6.6. BATTERY TESTING
4.6.4. BATTERY STORAGE
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 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.
If mower is to be stored out of season on its rear
bumper, it is recommended the battery be
removed, charged and stored.
1. Remove battery. Refer to Section “BATTERY
REMOVAL”.
2. Perform battery service.
3. Bring battery to full charge, if required.
4. Store battery in an area away from the RIDER on
a wood surface. DO NOT STORE BATTERY ON A
CONCRETE SURFACE.
4.6.5. NEW BATTERY PREPARATION
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. Filling battery with electrolyte will bring the
battery to 80% charged state.
4. With cell caps removed, connect battery charger
to battery terminals; RED to positive (+) and BLACK
to negative (-) terminal.
