Loader Control Joystick/Drive
Control Joystick Removal and
Installation
There are two joysticks that control the operation of the
machine: a drive control joystick and a loader control
joystick.
Drive Control Joystick Operation – The left-hand
joystick controls the speed and direction of the ma-
chine. The further the joystick is pushed, the faster the
machine travels. The joystick operates on hy-draulic
charge pressure. When the joystick is moved, oil is
sent to the hydrostatic transmission. The transmission
then delivers oil, in the correct amount, to the drive
motors.
