Overview

Description

Engine
  • Our FT4/Stage IV diesels deliver the best combination of performance, efficiency, and reliability. They 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.
  • Optional programmable fan automatically reverses at predetermined intervals, ejecting debris from the radiator and cooler cores. Or set your own cleaning cycles through the monitor.
Transmission and Axles
  • With ride control, the lift cylinders act as shock absorbers, cushioning bumps to allow these loaders to navigate rough ground more quickly without losing their loads.
  • Automatic differential lock engages as soon as a tire begins to slip. It's ideal for inexperienced operators or applications requiring high traction, such as stockpiling silage, plowing snow, and handling pipe.
Maintenance
  • All daily service points including fuel are grouped on the left side of the machine for quick and convenient access.
  • Hinged panel tilts away for quick ground-level access to both the fuel and diesel exhaust fluid (DEF) tanks, making refills convenient and easy.
Controls
  • Choose single-lever joystick or two-lever fingertip pilot-operated hydraulic controls.
Linkage
  • Z-Bar linkages provide high bucket breakout forces, reliable rollback to carry loads without spilling, and solid transport stability. A standard pin-on coupler or an optional hi-vis coupler adds versatility, reduces costs in a variety of applications, enables faster cycle times, and lowers operating weights.
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.
