Section 4 - ADJUSTMENTS & REPAIR
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 drive wheels off the ground. Wheels should be high enough to rotate freely. Secure with safety blocks.
3.Disconnect parking brake rod from parking brake lever. See Figure 4.4.
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 be still, 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.
9.Reconnect park brake rod.
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 and 25 psi in rear caster tire. Pressure in front deck caster wheels should be 25 psi.
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.
