Challenger Rogator 618 Hydrostatic Self Propelled Sprayer
Rogator 618
Designed with the toughest operating conditions in mind, the Challenger RoGator 618 offers exceptional strength and durability, together with performance that ensures optimum output in all conditions.
Engine & Chassis
Fitted with the common rail 6 cylinder Sisu CTA7.4 L 247 hp, you can be guaranteed excellent performance, regardless of operating conditions. Designed for high-speed operation with very heavy loads in extreme conditions, the welded steel space frame chassis and axles have proved to be very durable and can comfortably manage a 5,000-litre, 36-metre spray pack in liquid fertilizer applications. The front and rear axles can be fitted with the option of hydraulically adjusted track, 1.8 - 2.25 metres. The underside has an extremely smooth profile with a clearance of up to 1.1 metres to minimize crop damage.
Transmission
In simple terms, the 3-speed hydrostatic system fitted to the Challenger RoGator 618 exceeds all expectations. On this vehicle, the transmission only utilizes about 50% of its design capacity, even when fully laden. All four high-capacity wheel motors are fitted with oversize bearings. This ensures that they are well protected from the inevitable excess loads experienced when traversing rugged terrain with a full payload. The high flow twin pump system delivers massive torque to all four wheel motors at lower pressures than competitive machines, thereby further enhancing durability. The twin pump system, crossover plumbing and special “hill climb” steep cam wheel motor control, provides excellent gradeability for surefooted traction in the most difficult conditions.
Cab
Designed specifically for the market leading North American RoGator, the spacious, pressurized cab is the essence of luxury, comfort and safety. Easily accessed up the automatically folding steps and through a wide door, the fully trimmed, ISO-mounted cab with its pneumatic suspension seat provides the driver with a quiet and comfortable workstation, ideal for extended working periods. The large interior also allows for practical use of the foldout driver training seat. Comprehensive instrumentation and logical controls make light work of operation, whilst the large glass area provides excellent visibility particularly to the all important rear three-quarter area, giving perfect line of sight to the spray boom on each side.
A further major advantage of the Challenger RoGator 618 cab is that it is designed to exceed ECPAR / ASAE 525 test requirements for sprayer cabs. The high capacity heating and air-conditioning system maintains a fresh and comfortable environment for the operator, irrespective of ambient conditions.
Steering & Braking
The hydrostatic steering system is light and precise, and the simple-to-operate four-wheel-steer system provides excellent manoeuvrability on the headland. The steering wheel is fully adjustable to allow the operator to find the ideal position. In addition to the braking effort provided by the hydrostatic system, safe and dependable braking is provided by large high capacity drum brakes fitted to all four wheels. Even when fully laden, the braking system inspires confidence, allowing the operator to work the Challenger RoGator 618 to its full potential even on the most difficult terrain.
Suspension
The chassis is fully suspended. The rear axle is mounted via two heavy-duty Aeon suspension units, whilst the front is equipped with a hydrostatic suspension system for an extremely comfortable ride.
Driveability
The Challenger RoGator 618 is simplicity itself to operate. Gear selection is electro-hydraulic whilst engine speed is controlled electronically, either by use of the foot throttle or a rocker switch control.
