Overall Width
In order to calculate the width of the machine, add 800 mm (31.5 inch) to the gauge of the belts. See the example for a machine with gauge of 1524 mm (60 inch).
1524 mm (60 inch) |
+ | 800 mm (31.5 inch) |
= | 2324 mm (91.5 inch) |
Note: Add an additional 13 mm (.5 inch) when the machine is equipped with 813 mm (32 inch) belts.

Transmission
 | |
| Illustration 8 | g00344647 |
The transmission is a direct drive power shift transmission. The transmission has the following standard features:
- 16 forward speeds
- Nine reverse speeds
- Programmable electronic controls
- Six methods of shifting
An optional creeper transmission provides an additional 16 forward speeds and an additional nine reverse speeds. All of the creeper speeds are below 3.2 km/h (2 mph). When the creeper speed is engaged the speed reduction is 10.6:1 .

Brakes
 | |
| Illustration 10 | g00344896 |
The machine uses oil cooled multi-disc brakes. One multiple disc brake is located on each side of the machine. Both brakes are actuated by the service brake pedal.
The parking brake is a dry disc brake. The parking brake acts on the input shaft for the differential steer unit. In emergency conditions, use the parking brake as a secondary brake system.
