The much anticipated Challenger RoGator 600 self-propelled sprayer range will make its UK debut at Cereals 2010.


The new machines have unique features in every area and set the new standard for the sector, says makers Challenger.

The RoGator 600 sprayers are packed with new innovations, developed specifically to meet the high performance and accuracy requirements of professional operators.

The uncompromising “clean sheet” design, engineering quality and new technology combine to provide ultimate output, exceptional application accuracy and the highest levels of operator comfort and control.

There are three models, all powered by the latest generation AGCO SISU Power engine. The 49 CWA, four-cylinder, 4.9 litre capacity provides a maximum power of 175hp in the 635 model, while the two larger models are equipped with the 7.4 litre capacity 74 CTA, six-cylinder generating maximum powers of 210hp in the 645 and 236hp in the 655. Engines are side-mounted, between the two axles, which keeps the centre of gravity low and enhances weight distribution.

All machines feature the highest specifications and are built on a unique single beam chassis. This is equipped with a novel hydraulic working height adjustment, allowing operators to raise the sprayer 45cm from the standard 75cm working height to provide 1.2m of clearance. The track width can also be adjusted from between 1.8m to 2.25m, hydraulically or manually.

Independent suspension on all four wheels offers superb stability and comfort, and comes with an Electronic Stability Program (ESP) for maximum safety at transport speeds. Four-wheel steer is also standard and works in three modes: 2WS, 4WS and Crab, providing a turning radius of just 4.73m (to the outside) from its 35° steering angle – even with 2m high, 800mm wide tyres.

A load sensing, hydrostatic pump is attached directly to the engine. This offers CVT-like operation providing speeds from 0-40km/hr without the need to change ranges. Completely new wheel motors, exclusive to the RoGators, incorporate a planetary reduction unit and in-board brakes and are fitted within the wheel centres to reduce crop damage.

These are linked through an Active Slip Regulation system, which maintains traction in all conditions by regulating each wheel independently.
