Features

Engine

Our FT4/Stage IV diesels employ field-proven cooled exhaust gas recirculation (EGR), easy- to maintain high-uptime exhaust filters, and selective catalytic reduction (SCR).

Quad-Cool™

Quad-Cool places the radiator, air-conditioner condenser, intercooler, and hydraulic, transmission, and optional axle coolers in a unique boxed configuration that's isolated from engine heat.

Transmission and Axles

Automatic torque-converter PowerShift™ transmission with adjustable clutch cutoff feature improves productivity.

Maintenance

All daily service points, including fuel, are grouped on the left side for quick and convenient ground-level access. Sight gauges enable quick fluid-level checks.

Controls

Choose single-lever joystick or two-lever fingertip pilot-operated hydraulic controls.

Simple, easy-to-use payload weighing, powered by Loadrite™ technology, is integrated into the LCD color monitor and is available factory- or field-installed for Z-Bar and High-Lift machines.

Hydraulics

Our production-class loaders have two hydraulic pumps as part of a closed center and load sensing system.

Safety & Security

Sealed-switch module keeps out dust and moisture while eliminating nearly 100 wires. Prevent unauthorized machine operation with keyless-start requiring a numeric pass code.

Optional rearview camera and radar object-detection system
