IMPORTANT: To begin movement (forward or backward) the operator must
be in the seat, the brake lever must be disengaged (pushed down) before
the motion control levers can be moved in or the engine will kill.
When levers are centered in the T-slot the drive system is in the neutral position.
With levers moved out in the T-slot the drive system is in the neutral lock
position (See Figure 7).
FIGURE 7
MOTION CONTROL POSITIONS
By moving both levers an equal amount forward or back from the neutral position
the machine can be caused to move forward or backward in a straight line.
Movement of the left lever forward will cause the left drive wheel to rotate in a
forward direction. Movement of the right lever forward will cause the right
drive wheel to rotate in a forward direction. To stop forward travel, pull the
levers back to the neutral position.
To turn left while moving forward, move the left lever back toward neutral to
slow the left drive wheel.
To turn right while moving forward, move the right lever back toward neutral to
slow the right drive wheel.
To make a zero turn to the left, pull the left lever back beyond neutral while
holding the right lever slightly ahead of neutral.
To make a zero turn to the right, pull the right lever back beyond neutral while
holding the left lever slightly ahead of neutral.
Pulling the levers back from the neutral position will cause the respective drive
wheels to rotate in a reverse direction (spring tension can be felt when moving
into reverse from neutral).
To turn to the left while backing, move the left lever forward toward neutral. To
turn to the right while backing, move the right lever forward toward neutral.
CAUTION
POTENTIAL HAZARD
♦ Machine can spin very rapidly by positioning one lever
too much ahead of the other.
WHAT CAN HAPPEN
♦ Operator may lose control of the machine, which may
cause damage to the machine or injury.
HOW TO AVOID THE HAZARD
♦ Use caution when making turns.
♦ Slow the machine down before making sharp turns.
4.1.3 Tracking Adjustment Knob: Located under the seat on the LH pump control link.
Rotating this knob allows fine tuning adjustments so that the unit tracks straight
with the drive levers in the full forward position.
