DANGER
Exercise EXTREME CAUTION when making this adjustment, due to close proximity of moving parts.
4.1NEUTRAL 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.
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.

4.2MOWER DECK & COMPONENT ADJUSTMENTS 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.
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 (Turf Type Tires), 5 psi (All Terrain Type Tires) and 25 psi in rear caster tires. Pressure in front deck caster wheels should be
25psi.
If tires are properly inflated and mowing is still uneven, adjust deck levelness as follows:
1.Place mower on a smooth level surface.
2.Raise deck to highest cutting position.
3.Place 2x4 blocks under front edge of deck beside caster wheels. Blocks should be on both sides of deck. Make deck relatively level by positioning blocks. Both caster wheels must be off the ground.
4.Loosen leveling bracket at center rear deck support. See Figure 4.2. This allows the lift arm to settle down into hitch brackets.
