Slope adjustment of armrests (if equipped) | |
Use the following procedure to adjust both of the control supports (1), if necessary.
- Pull lever (1A) upward that is on the outside of armrest (1).
- Pull control support (1) in a forward direction or rearward direction to a comfortable position.
- Release lever (1A).
Use this switch to select the machine speeds.
|

| Illustration 3 | g01352060 |
|
REVERSE (4A) - If equipped, slot (4A) is for REVERSE. The machine speed will increase as the lever is pulled rearward. |
|
PARK (4B) - Place the lever in position (4B) to put the machine in the PARK position. |
|
NEUTRAL (4C) - Place the lever in position (4C) to put the machine in the NEUTRAL position. |
|
FORWARD (4D) - Slot (4D) is for FORWARD. The machine speed will increase as the lever is pulled rearward. |
Joystick Control (If Equipped)
| |
| Illustration 4 | g01389432 |
Note: The Joystick Control has two patterns for steering the machine, an S pattern that is the factory default and a C pattern that is optional. Changing the pattern using a service tool is possible. The older machines may require a software update to allow the C pattern.
|
|
FORWARD (4E) - To move the machine in the forward direction, push the joystick forward. The machine speed will increase as the joystick is pushed forward. |
|
|
NEUTRAL (4F) - For optional steering C pattern, the machine will not counterrotate in NEUTRAL. For the default steering S pattern, the machine will counterrotate when the joystick is moved to the right or left while the machine is in NEUTRAL. |
|
|
REVERSE (4G) - To move the machine in the rearward direction, pull the joystick rearward. The machine speed will increase as the joystick is pulled rearward. |
Note: When you place the joystick in FORWARD or REVERSE, the joystick will maintain the FORWARD or REVERSE position until you change the position of the joystick.
| |
| Illustration 5 | g02031255 |
When your machine is equipped with the control joystick, the machine also has six speed ranges (1.0 to 3.5) in both forward and reverse. The current speed range is shown on the digital display window.
To increment the speed ranges, press the top right button (4H) on the joystick. To decrease the speed ranges, press the bottom right button (4I) on the joystick.
If your machine is equipped with the joystick control for the transmission, press the top left button (4J) on the joystick to sound the horn.
The pedals on either side of the brake control pedal provide steering control. As a pedal is depressed, the speed of the track on that side is reduced to provide steering capability. As either pedal is depressed to a certain point, the speed of that track is reduced to zero. Depressing a pedal all the way causes that track to rotate in the opposite direction of the other track. The opposite rotation provides spot turn operation (counterrotation of the track). Releasing the pedal returns the track to normal operation.
Joystick Control (If Equipped)
The Joystick Control has two patterns for steering the machine, an S pattern that is the factory default and a C pattern that is optional. Changing the pattern with a dealer service tool is possible.
