BREAKTHROUGH COMFORT AND VISIBILITY

Seat and controls

  • The seat mounted armrest gives more accurate control and comfort. It features 3rd/4th function proportional control integrated in the joystick.
  • New Joystick Steering: the operator handles two equally sized joysticks, just like on an excavator, which reduces fatigue. It features speed proportional sensitivity and slow/medium/fast settings.
  • The suspended seat includes seat heaters which warm it up in the cold winter mornings.

User interface

  • The premium control interface with 8’’ color display offers intuitive navigation through the machine’s information and settings.
  • The hands free calling kit features an integrated microphone connected to the radio via bluetooth.

Life on board

  • The CASE electrically powered cool box keeps your lunch fresh all day long.
  • Multiple storage areas enable you to store documents, beverages and personal objects conveniently

HIGH EFFICIENCY

With no EGR or particulate filter

The engine was developed and manufactured by our award winning sister company FPT Industrial, which produces over 500,000 engines per year and powers world record winners.

The in-house design leverages advanced technologies developed for commercial vehicles and agriculture, and introduces specific tailored solutions for off-road applications.

The engine, is designed to offer both fuel efficiency and reliability with plenty of power available.

  • The air intake flow is increased by a turbocharger with air-to-air cooling.
  • The multiple injection delivers best-in-class high torque performance at low rpms.
  • No EGR valve is used: 100% fresh air is taken for combustion without DPF and no extra cooling system is needed.

Our engine technology is so reliable that it is trusted by the French Sea Rescue service for their boats: what better guarantee could you wish for?

BULLET PROOF RELIABILITY

Heavy-duty axles

The heavy-duty axles are tougher, bigger and easier to service thanks to the 3-piece housing design. Wet multiple disc brakes, made of resistant sintered bronze, are located in each wheel hub. Our heavy-duty axles are engineered to support L5 or solid tyres for very abrasive environments. Solid tyres can be factory fitted.

A higher value results from:

  • 20-30% lower tyre wear because of no slippage between the wheels;
  • Reduced fuel consumption because there is no friction in the differential
  • Reduced downtime for maintenance because of fewer moving components with open differentials.

100% auto lock differential

With open differentials, no friction is applied to reduce wheel slip. As a result, there is less tyre wear and lower energy losses. With the 100% Auto-lock, 100% of the available torque is transmitted to the wheels to provide maximum tractive effort.

Case cooling cube

The unique design of the CASE cooling cube, with five radiators mounted to form a cube instead of overlapping, ensures a constant flow of fresh and clean air from the sides and from the top, to maintain constant fluid temperatures. The cube structure provides easy access to radiators for a more effective cleaning and serviceability: additional cleaning can also be easily done manually, with separate access to each radiator.

Designed for dusty environment

The cooling system is mounted behind the cab, far from the rear bumper of the machine and from the ground: away from the dust.

GROUND LEVEL SERVICEABILITY

GROUND LEVEL SERVICEABILITY

One-piece electric hood

The positioning of the engine at the rear and the easy-to-open electric hood provide fast access to the service points. Jumper cables are available as standard for jump starting the engine if the battery is low.

Grouped service points

Don’t be surprised if you don’t see any safety handrails around the hood or steps behind the rear wheels, all service points are easily accessible at ground level. You can do a fast visual check of the hydraulic and transmission oil levels. The three drains are grouped together on the left side, so that fluids are easy and quick to replace.

Greater safety

All the main service points are easily accessible from the ground, so you can carry out your daily maintenance safely and efficiently.
