Greater digging power and increased lift capacities are the result of the Spool Stroke Control (SSC) system, which reduces pressure loss and distributes hydraulic oil more smoothly. Pilot pressure sensors detect the type of work being done, such as digging or leveling, and then relays that data to proportional solenoid valves that quickly determine where optimal hydraulic pressures should be directed for that operation.
Two electronically-controlled Kawasaki variable-displacement axial-piston pumps and one Kawasaki gear pump assure that hydraulic power is delivered precisely when and where it’s needed. At the same time, hydraulic flows in noncritical areas of the system are reduced. The result is better breakout force, more lifting strength and faster machine response.
• Proprietary hydraulic system
• New control valve with larger ports; less restriction means improved hydraulic flow for increased performance
• Electronically-controlled pumps for improved cycle times, quicker response and more efficient machine operation
• Move more dirt per gallon of fuel
The X4 Series features innovative EPA-certified Final Tier 4 engines from Isuzu that strike a balance between power, productivity and fuel efficiency.
