Mechanical Controls
Caterpillar sets the standard in power and precision with load-sensing hydraulics.


Load-Sensing Hydraulic System
The variable displacement piston pump and flow-sharing hydraulic valves sense work demand and adjust flow and pressure for increased productivity. Load-sensing hydraulics deliver:
  • Maximum lift and dig forces at any engine RPM
  • Cooler hydraulic system
  • Better fuel efficiency
  • Quieter operation
  • Reduced wear on components

Hydraulic Pump
The variable displacement piston pump improves implement response and speed while still providing high forces at any engine speed. A supplemental gear pump provides increased flow and responsiveness.

Torque Limiter Control
The pump torque limiter control manages distribution of engine power to the hydraulic system and drive train. E-Series improvements produce more aggressive backhoe digging and stronger truck loading performance.

Flow-Sharing Hydraulic Valves
Technology leveraged from Cat Hydraulic Excavators, new flow-sharing hydraulic valves automatically distribute flow to optimize multi-function implement performance. Closed-center implement valves signal hydraulic system requirements to a control valve located on the pump.

Clamps and Bushings
Metal clamps with rubber bushings are used at hose attachment points to eliminate metal-to-metal contact and increase wear life.

Cat XT-3 ES ToughGuard™ Hoses
Improved bend radius and abrasion resistance provide reliable long life in the toughest conditions. Made of four overlapping, insulated wire spiral wraps bonded together for durability, Cat XT-3 ES (Enhanced Spiral) ToughGuard hoses exceed SAE certification standards. The hose routing protects them from work damage, and hose failure is substantially reduced. Cat XT-3 ES ToughGuard hoses combined with Cat couplings and O-ring face seal fittings provide a leak-free system. All backhoe hydraulic circuits utilize the new ToughGuard hose with extended wear characteristics.

Power Train

Air Cleaner
A dry-type axial seal air cleaner with automatic, integrated dust ejection system provides more efficient pre-separation. The two-stage air filter incorporates both air cleaner and precleaner functions into a single unit mounted under the hood.

New Axles
New heavy-duty axles are designed specifically for demanding backhoe loader applications. Features include outboard planetary gear sets and brakes for serviceability and longer life.

Auto-Shift Transmission
The standard automatic transmission matches gears with grade and load conditions. Top gear is selected with the twist grip control on the steering column. At the touch of a switch, manual mode gives the operator control over gear selection, as a power shift transmission.

Transmission Kick-Down Switch/Neutralizer
Located on the loader control, the kick-down switch allows the operator to downshift through the gears. When this switch is depressed for more than one second, it serves as the transmission neutralizer to maintain engine and hydraulic speed when truck loading.

Standard Four Wheel Drive (4WD)
Heavy-duty front drive axle can be engaged at any time by activating the switch on the front console. The switch can be activated while the machine is stopped or moving, with or without load. 4WD features outboard planetary gear final drives and improves mobility and loader performance in poor traction conditions.

Brake Mode Selector
The brake mode selector switch has three positions: two wheel drive, two wheel drive with all wheel braking and all wheel drive. Center position provides two wheel drive for better tire life while roading and engages the front axle when brakes are applied for improved braking performance.

Ride Control
Standard Caterpillar Ride Control delivers even greater operator comfort.

Ride Control

Ride Control System
The Ride Control System incorporates a nitrogen accumulator in the loader lift circuit that smooths the ride in all conditions, including load and carry, highway roading, or simply moving around the job site.

Improved Productivity
Ride Control improves material retention in the loader bucket for increased productivity and a cleaner jobsite.

Ride Control reduces machine loping, providing a smooth and stable ride for increased operator comfort and reduced operator fatigue.

Convenient Operation
The system is easily engaged by a switch on the front console. The Ride Control switch has three positions, ON, OFF and AUTOMATIC. In the automatic position, the Ride Control engages automatically as the travel speed increases. At low speed, the system disengages for loading, grading or finishing applications.
