This machine is driven and controlled by the following systems.
- The main hydraulic system controls the following systems: the variable gauge cylinders, the oscillator and the travel motors.
- The pilot hydraulic system supplies oil to attachment selection valve (15) and attachment (14) .
The main hydraulic system delivers oil flow from idler pump (22) and drive pump (23) to swivel (16) in order to control the following components: left travel motor (2) , right travel motor (9) , attachment (14) and variable gauge cylinders (12) and (17) .
