Features

Main Pumps

The hydraulic system includes three pumps with an independent swing circuit. The hydraulic circuit utilizes a load-sensing system to ensure high efficiency and productivity with little hydraulic loss.

Swing Dampening Valve

A swing dampening valve reduces wagging, which produces smoother, time-saving swing stops.

Implement Pressure

Increased implement pressure provides shorter cycle times, stronger digging forces and greater bucket fill factors.

Auxiliary Hydraulics

Standard auxiliary hydraulics are managed electronically, making the machine more versatile.

Proportional Priority Pressure Compensation (PPPC) Hydraulics

The load-sensing PPPC system with proprietary electronic actuation provides excellent efficiency and controllability.
  • Pump discharge flow matches the operator's desired speed, which makes for extremely smooth shifting from neutral to full stroke.
  • Pump flow volume all goes to the actuator, which ensures the delivery of maximum hydraulic energy. Even if load pressure changes during actuation, the control lever position does not vary, which makes for consistent, reliable operation.
