 Hydraulic system has built-in reliability and provides exceptional lift, breakout and auxiliary power to work tools.
Maximum power and reliability are built into the Cat Skid Steer Loader hydraulic system. In addition to providing power to drive the wheels, this system also provides the loader lift and tilt functions, powers the auxiliary circuit to drive work tools and drives the engine cooling fan.
The hydraulic pumps are driven directly off the engine for maximum hydraulic performance and reliability - no belts are used. Pumps are fixed-displacement and provide flow to the loader and auxiliary circuits at 60 L/min (15.6 gal/min) at high idle. Maximum system pressure for the loader and auxiliary circuit is 21 400 kPa and 3110 psi.
Standard auxiliary hydraulics to power work tools is available through quick connect hydraulic couplings that are rigidly mounted to the loader arm. The Caterpillar line of high pressure XT™ ES hoses and O-ring face seals help assure a leak-free system.
 Hydraulic system reliability and cleanliness are improved by using single components in place of multiple components, such as the monoblock hydraulic valve and monoblock pumps. Fewer leak points improve reliability and result in a cleaner machine.
In addition, hydraulic oil flows through a 5-micron, spin-on filter. A filter restriction indicator is located in the operator station. A 74-micron screen in the hydraulic tank prevents larger debris from entering the system and causing damage to the hydraulic components.
A high-efficiency, hydraulic oil cooler lets the Cat Skid Steer Loader work longer and harder in higher ambient temperatures, even when using continuous high flow work tools. The high capacity, hydraulic oil reservoir also helps keep operating temperatures lower.
World-class operator station provides exceptional working comfort with excellent visibility, enhanced fingertip control and optimum instrumentation.
Caterpillar hystat power train delivers aggressive performance and easy operation.
