DRIVE CONTROL ADJUSTMENT

If the machine creeps (tires rotate slowly with steer-

noise indicating they are being slightly stroked, a

neutralizing adjustment is required.

To make a neutralizer adjustment, block the ma-

chine off the ground so that the wheels turn free-

pins. When the engine is running, stay clear of

the rotating wheels.

To make any transmission control linkage adjust-

position to access the transmission area.

Never work under a raised seat unless it is se-

curely latched in the raised position.

Control lever, 1; link, 2; and arm, 3, control the right

side. Control lever, 4; link, 5; and arm, 6 control the

left side. There are shock absorbers, 7, connected to

the steering linkage to dampen the hydraulic vibra-

tion from the control levers to the operator's hands.

The neutralizer plate, 8, is spring loaded to return the

arms, 3 and 6, to their neutral position.

When the operator strokes both control levers in the

the levers are stroked differently to change direction
