Section 5 - ADJUSTMENTS & REPAIR  
4.2 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.  
4.1 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.  
4.2.1. 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.  
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.  
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 4.1.  
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.  
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 measure-ment 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.  
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

(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 4.2A.  
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 4.2.  
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.

4.7.4. 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.  
4.7.5. 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!

2 YEAR LIMITED WARRANTY  
For two (2) years from purchase date for the original purchaser's use, SNAPPER, through any authorized  
SNAPPER dealer will replace, free of charge (except for taxes where applicable), any part or parts found upon  
examination by the factory at McDonough, Georgia, to be defective in material or workmanship or both.  
®
SNAPPER FIELD SERVICEABLE SPINDLES and their components used on SNAPPER PRO Mid Size walks

in material or workmanship or both.  
All transportation costs incurred by the purchaser in submitting material to an authorized SNAPPER dealer for  
replacement under this warranty must be paid by the purchaser.  
This warranty does not apply to engines and their components, and batteries, as these items are warranted  
separately. This warranty does not apply to parts that have been damaged by accident, alteration, abuse,  
improper lubrication, normal wear, or other cause beyond the control of SNAPPER. This warranty does not  
cover any machine or component that has been altered or modified, changing safety, performance, or durability.  
Batteries have a one (1) year prorated warranty period with free replacement if required during the first ninety  
(90) days from the original purchase date. SNAPPER will not be responsible for any installation cost incurred.  
The battery warranty only covers original equipment batteries and does not cover damage to the battery or  
machine caused by neglect or abuse, destruction by fire, explosion, freezing, overcharging, improper  
maintenance, or use of improper electrolyte.  
There is no other express warranty.  
DISCLAIMER OF WARRANTY  
Implied warranties, including those of merchantability and fitness for a particular purpose, are limited to  
two (2) years from purchase date for the original purchaser's use, and up to the extent permitted by law  
and all implied warranties are excluded. This is the exclusive remedy. Liabilities for consequential  
damages, under any and all warranties are excluded.  
Some states do not allow limitations on how long an implied warranty lasts, or do not allow the  
exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may  
not apply to you.  
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

IMPAIR THE SAFETY OF SNAPPER PRODUCTS AND WILL VOID ANY LIABILITY AND WARRANTY BY
