5.2 MOWER DECK & COMPONENT ADJUSTMENTS
DANGER
The following mower deck and component
adjustments and repairs can be made by the owner.
However, if there is difficulty in making these
adjustments and repairs, it is recommended that
these repairs be made by an authorized SNAPPER
dealer.
Exercise EXTREME CAUTION when making this
adjustment, due to close proximity of moving parts.
5.1 NEUTRAL POSITION ADJUSTMENTS
The joystick controls the movement and stopping of
the machine. Move the joystick to the center or
neutral position to stop machine. IMPORTANT:
Always return the joystick with hand assistance
to the neutral position. If machine does not come
to a complete stop or has any movement when
joystick is moved to the neutral position,
adjustment must be made.
5.2.1. MOWER DECK ADJUSTMENT (LEVELNESS)
SIDE to SIDE and FRONT to REAR
Before making deck leveling adjustments,
check tires and add or release air as needed to
bring pressure to 12 psi in drive tires. Pressure
in front caster wheels should be 25 psi.
If tires are properly inflated and mowing is still
uneven, adjust deck levelness as follows:
1. Turn key to “OFF” position.
2. Raise both wheels off the ground. Wheels should
be high enough to rotate freely. Secure with safety
blocks.
3. Disconnect parking brake rod from parking brake.
See Figure 4.3.
4. Engage parking brake lever. NOTE: Engaging
parking brake without brake rod connected will lock
joystick in center or neutral position.
5. Turn key to start position and start unit.
6. Both wheels should not have any movement, not
rotating.
SIDE to SIDE LEVEL
1. Place machine on a smooth level surface.
2. Check blade tips by rotating blades until tips
are pointing to the sides of the deck. Check the
measurement of outside blade tips to the
ground on both blades. The measurement of
each of the outside blade tips should be within
1/8” of each other. If measurement of the blade
tips is not within 1/8”, adjustment should be
made to the higher side of the deck to lower it
to within the correct measurement.
7. If wheel(s) are rotating, disconnect transmission
control rods from cross shaft and turn adjusting bolts
located on pump(s) clockwise, or counter-clockwise,
until wheel(s) stop rotating. See Figure 5.1
8. With wheels in neutral, (not rotating) stop engine
and readjust control rods until they fit into the cross
shaft arms with no wheel creep.
3. Move deck lift lever and set the mower deck
to the highest cutting position.
4. Place a wooden block under the front and
rear edge of the mower deck.
5. Move deck lift lever and set the mower deck
to a lower cutting position until deck rests on
wooden blocks.
9. Reconnect park brake rod.

(Continued)
11.Place a wooden block under the front and
rear edge of the mower deck.
12.Move deck lift lever and set the mower deck
to a lower cutting position until deck rests on
wooden blocks. This will relieve pressure
from deck lift components.
13. NOTE: The timing rod connects the front
and rear lift arms and maintains the deck in the
same attitude through all heights of cut. Adjust
the deck by loosening and rotating the timing
rod adjusting nuts. Rotate both nuts forward to
lower the rear of the deck or rearward to raise
the rear of the deck. Tighten the nuts securely.
See Figure 5.2A.
6. Loosen the nuts and bolts that secure both
front and rear deck support brackets on the
high side of deck. Located above each support
bracket, on the top part of the power unit
frame, are three shim plates. Remove the shim
plates on both of the front and rear lift arms and
position plates between the support bracket
and the frame of the power unit. Inserting the
shim plates in this procedure will lower that side
of the deck. Retighten the support bracket nuts
and bolts to 20 to 30 ft. lbs. of torque. See
Figure 5.2.
14. Raise cutting deck to highest cutting
position and check measurement. If blade
tips are not within correct measurement
repeat steps 8 through 13 until deck is level.

5.7.4. BATTERY TESTING
WARNING
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
before testing. The Battery Condition Chart
shows the charge level as measured by
syringe float hydrometer, digital voltmeter
and five ball hydrometer.
DO NOT attempt to service or charge the battery
while it is installed in the machine. DO NOT use
“BOOST” chargers on the battery.
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. Install battery into power unit.
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. Install battery retainer and positive
terminal cover.
5.7.5. NEW BATTERY PREPARATION
1. Remove battery from carton.
WARNING
Shield the positive terminal with terminal cover
located on battery harness. This prevents 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.
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. With cell caps removed, 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.
WARNING
DO NOT OVERFILL!
