Challenger RoGator 618SThe ultimate vehicle for spraying and spreading systems, for the most demanding farmers and contractors. Designed with the toughest operating conditions in mind, the Challenger RoGator 618S offers exceptional strength and durability, together with performance that ensures optimum output in all conditions.

Matched with the appropriate sprayer orspreader, the Challenger RoGator 618S can return consistently high work rates over extended periods to ensure thatapplications are made in a timely andefficient manner, even over extremelylarge acreage.

Combine this with the back-up of theChallenger dealer network, closelysupported by the parts and service network of the world’s largest, dedicated agricultural machinery manufacturer, you have a package unrivalled in the industry.

Efficient Power

AGCO’s own SISU 7.4 litres 6 cylinder74CTA engine meets the latest emissionregulations and is tailored specifically tomeet the power and torque demands ofthe RoGator’s Hydrostatic transmission,ensuring the optimum in power and fueleconomy form one of the worlds mostrespected diesel engines.

RoGator’s engine bay offers excellentaccess to all maintenance tasks via twosliding engine covers, which protectengine, cooling package and hydraulicsystems and control external noisemaking the RoGator 618S quiet on theoutside as well.

Chassis

Designed for high-speed operation withvery heavy loads in extreme conditions,the welded steel space frame chassisand axles have proved to be very durable and can comfortably manage a5,000-litre, 36-metre spray pack in liquid fertiliser 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 aclearance of up to 1.1 metres to minimise crop damage.

Setting New StandardsTransmission

In simple terms, the 3-speed hydrostatic system fitted to the Challenger RoGator 618S exceeds all expectations. On this vehicle, the transmission only utilises about 50% of its design capacity, even when fully laden.

All four high-capacity wheel motors arefitted 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 systemdelivers massive torque to all four wheelmotors at lower pressures thancompetitive machines, thereby furtherenhancing durability.

The twin pump system, crossoverplumbing and special “hillclimb” steepcam wheel motor control, providesexcellent gradeability for surefootedtraction in the most difficult conditions.To further demonstrate Challenger’sconfidence in the RoGator 618S, where local legal regulations allow, the vehicle has been tested and approved to tow a trailer with a gross laden weight of 16 tonnes.

Cab

On competitive self-propelled sprayers,the cabs often appear to be something ofan afterthought. Not so with theChallenger RoGator 618S. Designedspecifically for the market leading NorthAmerican RoGator, the spacious,pressurised cab is the essence of luxury,comfort and safety. Easily accessed upthe automatically folding steps andthrough a wide door, the fully trimmed,ISO-mounted cab with its pneumaticsuspension seat provides the driver witha quiet and comfortable workstation, idealfor extended working periods.

The large interior also allows for practicaluse of the driver-training seat.Comprehensive instrumentation andlogical controls make light work ofoperation, whilst the large glass areaprovides 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 618S 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. The cab has a two-stage air filtration system. All incoming air passes through a standard dust filter first to remove particulates, before passing through a secondary, active carbon filter to provide protection from airborne chemicals. This arrangement greatly extends the life of the carbon filter when operating in dusty conditions.

Furthermore, even when operating theventilation system in re-circulation mode,all air passes through a third, activecarbon filter to ensure that any chemicalsbrought into the cab on the operator’sclothing are taken out of circulation

Steering

The hydrostatic steering system is lightand precise, and the simple-to-operatefour-wheel-steer system providesexcellent manoeuvrability on the headland. The steering wheel is fullyadjustable to allow the operator to findthe ideal position.

Auxiliary Hydraulics

Powerful auxiliary hydraulics suppliedthrough 4 spool valves provide ampleflow for most applications and areplumbed so as not to be affected bydemand from either the transmission orsteering systems.

An additional, independent, high-flow,load-sensed hydraulic circuit completewith its own cooling system can bespecified as an option. This can provideadditional hydraulic flow directly to theimplement or a powered drive via achassis-mounted PTO system.

Braking

In addition to the braking effort providedby the hydrostatic system, safe anddependable braking is provided by largehigh capacity drum brakes fitted to allfour wheels. Even when fully laden, thebraking system inspires confidence,allowing the operator to work theChallenger RoGator 618S to its fullpotential even on the most difficultterrain. Separate parking brakes are fittedon each of the rear wheel motors.

Driveability

Once you drive the three seed Hydrostatic Transmission in the RoGator 618S it becomes clear that not all hydrostatic systems are the same. This system was designed specifically to meet the demands of modern agriculture, to drive it is to believe it.

RoGator offers 3 speed shifts on the move with a similar feel in operation to a power shift transmission. This combined with Challenger’s unique “drive sensing system gives tractor drivability in a hydrostatic machine. In transport this system can reduce fuel consumption whilst increasing driver comfort and confidence.

In the field operating with RoGator’s cruise control system, “drive sensing” ensures that maximum power is transmitted to the wheels at all times, giving exceptional power response for hill climbing and tough conditions.

On the road, the operator can also choose to make use of the “dynamic braking” control system. This allows forward speed and braking to be coordinated automatically. Once selected, depression of the foot throttle causes the vehicle’s forward speed to increase. On releasing the throttle pedal, the vehicle will slow down, through a combination of reducing engine speed and slowly increasing hydrostatic braking effort. Should the load/speed combination require it, applying pressure to the brake pedal will, at first, increase the rate of transmission deceleration, then with increased pressure will operate the powerful drum brakes on all four wheels.

This automatically controlled function provides a very smooth drive, reduces driver fatigue and greatly increases confidence when operating with heavy loads.

Suspension

The chassis is fully suspended. The front axle features a hydraulic self levelling system and rear axle has the option of two heavy-duty Aeon suspension units, or a self levelling airbag suspension system for an extremely comfortable ride.

Spray Packs

The choice of sprayer is often a very personal one. Many customers have preferences for features that are not available on all brands. For this reason,

Challenger is working with two manufacturers of sprayers - Chafer and Knight Farm Machinery. Together, we bring you the very best spraying technology in combination with the very best application vehicle - the ultimate solution for your application needs.

Spreader Body

For many years, Bredal have been successfully supplying spreader bodies for the Challenger RoGator 618S. These can be supplied with hydraulically drivendiscs or with the optional PTO-driven disc mechanism for high rate lime spreading.

Whatever your spreading or spraying needs, Challenger RoGator 618S has the solution for you.
