Drive Control
The PT-70/80 are equipped with
pilot operated joystick controls.
The drive control (left joystick) is
used to control track motion. The
illustration above shows the rela-
tionship between joystick and
machine movement.
Note: The machine will not
move as long as the drive con-
trol is in the neutral position.
Each joystick is equipped with a
spring return feature that auto-
matically returns it to neutral
position when released.
To stop a moving machine,
release the left joystick altogeth-
er. This will stop the machine.
Lift Arm Control
The lift arm control (right joy-
stick) is used to control the lift
arms and attachment (bucket)
movement. The illustration
above shows the relationship
between joystick and lift
arm/attachment movement.
The PT-70/80 are equipped with
a float function that allows the lift
arms and attachment (bucket) to
follow the contours of the ground
as you move with only their own
weight acting as downforce.
• To engage: push the joystick
fully forward into position.
(see illustration)
• To disengage: pull back
quickly on the joystick.
