STEP 10: MOWER DECK ADJUSTMENT (LEVELNESS)  
SIDE to SIDE and FRONT to REAR  
IMPORTANT: Re-check fluid level after operating machine  
for several minutes and adjust level as needed. If one or

setting of approximately 1” (1-1/4” for 61 deck), and the  
STEP 12: TRACKING ADJUSTMENT – TWIN STICK  
CONTROLS  
Start machine. If the machine does not track straight when  
the Motion Control Levers are in the maximum forward  
speed position, perform the following adjustment. Rear tire  
pressure must be set to 12 PSI before making this  
adjustment.  
A. Loosen bolts that secure adjustment plates and slide  
plates all the way forward. Retighten bolts.  
B. Start machine and drive in smooth flat open area at  
maximum forward speed.  
C. If machine tracks to the right, loosen bolts that secure the  
left adjustment plate. Move plate rearward to slow the left  
wheel. Retighten bolts.  
D. If machine tracks to the left, loosen bolts that secure the  
right adjustment plate. Move plate rearward to slow the right  
wheel down. Retighten bolts. See Figure 6.  
E. Drive machine again. Repeat adjustment as necessary  
until machine tracks straight.  
blades pitched approximately 3/16” higher at the rear. If  
adjustment is needed:  
A. Place machine on a smooth level surface.  
B. 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 correct measure-  
ment.  
C. Move deck lift lever and set the mower deck to the  
highest cutting position.  
D. Relieve tension on deck lift assist spring by loosening nut  
on eyebolt.  
E. Place 1” blocks (1-1/4” for 61 deck) under the front and  
rear edge of the mower deck.  
F. Set the mower deck to the lowest cutting position until  
deck rests on the blocks.  
G. Loosen the top nuts that secure both front deck support  
eyebolts. Adjust bottom nuts until eyebolts are tight, then  
retighten top nuts.  
H. Loosen the bottom nuts that secure both rear deck  
support eyebolts. Adjust top nuts until eyebolts are tight,  
then tighten bottom nuts securely.  
I. Set the mower deck to the transport position and recheck  
side to side blade tip dimensions. The difference between  
the two should be 1/8” or less.  
NOTE: The deck timing rod (rod that runs from front deck lift  
arm to rear deck lift arm) is preset at the factory and requires  
no adjustments.

J. The leveling blocks used in Step E should result in a prop-  
er deck pitch. If a pitch adjustment is required, use the two  
rear deck support eyebolts. Adjust up or down as required.  
K. Reinstall deck lift assist spring. Place deck in transport  
position. Tighten nut on eyebolt until 2-3/4” of threads pro-  
trude past end of nut.

STEP 11: HYDRAULIC OIL RESERVOIR  
Check the level of the fluid in both of the fluid reservoirs. The  
reservoirs are located underneath the operator’s seat. Wipe  
away all dirt and debris from around reservoir cap before  
removing. Oil must remain absolutely clean! Check with  
machine on a level surface with engine “OFF”. Fill reservoir  
as needed to bring level up. The reservoir is properly filled  
when the fluid level is 1½” below the top of the filler neck.  
DO NOT OVER FILL. Use clean, fresh premium automotive  
oil having a viscosity equivalent to SAE 20W50 API SL. The  
fluid should be chemically stable, incorporating rust and oxi-  
dation inhibitors. Make sure funnels, pouring spouts and oil  
can are completely clean. Reinstall reservoir cap.

STEP 13: HYDRAULIC SYSTEM, PURGING  
When initially putting hydraulic system into service, one or  
both of the wheel drives may not pull properly. This is  
likely to be caused by air entrapped in the system. If you  
experience a pulling issue during initial setup or after com-  
pleting repairs, perform the following procedure to purge  
the air from one or both of the hydraulic drive systems.  
IMPORTANT: WHEN REPLACING THE HYDRAULIC  
FLUID FILTER, PRE-FILL WITH OIL (SAE 20W50 API  
SL) BEFORE INSTALLING. PRE-FILLING THE FILTER  
WITH OIL WILL REDUCE OR POSSIBLY ELIMINATE  
THE NEED TO PURGE THE SYSTEM OF ENTRAPPED  
AIR.  
HYDRAULIC  
RESERVOIR  
A. Locate hydraulic reservoir underneath operator’s  
seat. After thoroughly cleaning the area around the top  
of each reservoir, remove filler cap. Bring fluid to  
proper level (1 ½” below the top of the filler neck). With  
engine off, add SAE 20W50 automotive oil. See  
Figure 7.  
FIGURE 7  
B. Open pressure relief valve on hydraulic pump, turn-  
ing counter clockwise 2 full turns. See Figure 8.  
C. Carefully raise the rear of the machine so the  
wheels are off of the ground. Securely block the  
machine to prevent it from falling.  
D. While seated in the operator’s position, start the  
engine. Place engine speed control in FAST position.  
E. Release parking brake and move motion control  
levers out of the neutral lock position.  
F. Slowly move motion control levers to the full forward  
and then to the full reverse positions. Repeat this  
process 6 times.  
G. Stop engine and wait for all rotation to stop before  
leaving the operator’s position.  
H. Close pressure relief valve on hydraulic pump, turn-  
ing clockwise. Tighten snuggly.  
I. With pressure relief valve closed, repeat Steps D  
thru G.  
ROTATE RELIEF VALVE  
COUNTERCLOCKWISE  
TO RELIEVE PRESSURE  
J. Remove blocks and lower rear of machine.  
K. Check fluid level in reservoir. Add SAE 20W50  
automotive oil as required to bring fluid level to 1 ½”  
from top of filler neck. Do Not over fill.  
L. Install and tighten filler cap.

PRE-OPERATION CHECKLIST  
Snapper has completed initial adjustments and performed operational tests prior to shipping the machine. Due to
