To place the drive levers in the "forward" position, slightly squeeze the drive
levers while placing thumbs on the outer thumb lobe of the neutral lock latches
(or the index finger on the front lobe) and rotate them from under the drive
levers. Slowly and carefully release the drive levers. See Figure 2 (c).
To place the drive levers in the "reverse" position, squeeze the drive levers
past the neutral position. See Figure 2 (d).

DRIVE LEVER, NEUTRAL LOCK LATCH OPERATION
3.3.4 Drive Wheel Engagement/Turning: With drive levers locked in "neutral", shift
speed control lever to desired forward speed.
Slowly squeeze and hold both drive levers in the neutral position and rotate both
neutral lock latches from the neutral lock position to the forward position.
DO NOT squeeze both drive levers all the way back. This will cause the drive
wheels to engage in the reverse direction.
For straight ahead motion: Smoothly release both drive levers to engage drive
wheels.
For turning: Squeeze the right hand drive lever to turn right and the left hand
drive lever to turn left. To make a "zero turn", squeeze either the left hand or the
right hand drive lever back into the reverse position while the opposite drive lever
is in a forward position at an equal but opposite speed.
For reverse: Squeeze both drive levers into the reverse position.
For smooth operation of this machine, avoid quick, jerky movements of the drive
levers. Move the drive levers smoothly and deliberately.
3.3.5 To Stop: Squeeze drive levers back to the "neutral" position. Move the neutral
lock latches into the "neutral lock" position and release drive levers. Move the
speed control lever to the neutral position.
