Caterpillar drives give John Deere 9620RX a new character.
The 15 litre, 6-cylinder engine provides 620 HP to the tractor, which has a gross weight of 24.9 tonnes out in the field. The CommandViewIII cab with a 7 or 10 inch touchscreen and four-pillar cab springing provides the farmer with a comfortable workstation. And with this tractor which displays its character at first glance, John Deere certainly provides an answer to the pressing questions of the present day, because large-scale agriculture is calling for increasingly powerful and more efficient problem solvers – and these include the John Deere 9620RX. More than 100 crawler tractors from this range are already in use in Europe. WIKING has now miniaturised down to 1:32 scale the mighty agricultural machine with its four drives. Obviously, all of these are functional. The traditional model makers have miniaturised the innovative tractor range to 1:32 scale in fine detail. The numerous functions of the mighty agricultural machine are a surprise which emphasises the usefulness of the prototype.
Benefits of caterpillar drives change daily life on the farm:The four caterpillar drives obviously create completely different driving characteristics for the mighty tractor. Even in hilly and wet conditions, through its track accuracy the 9620RX is a winner when turning under load. Because of its drive and the steering joints, it has a reduced tendency to create ridges compared with its tyred equivalent. As an inspection of the model shows, the 9620RX has an extremely narrow track width when in use, and is therefore ideal for transport journeys on public roads. Noteworthy: because of its increased contact area, the tractor has a very low tendency to compact the soil. John Deere is supplied by Camso who, as the sole manufacturer of caterpillar drive systems, provides the components for the manufacture of the whole 9RX series. This applies equally to the caterpillar tracks, rubberised drive wheels, and track rollers.
The caterpillar tracks contain more rubber and woven-in steel threads, in order to increase the working life of the caterpillar track and of the guide studs in heavy-duty applications on a slope, as well as for frequent journeys on public roads. The two track rollers keep the caterpillar tracks in contact with the ground over the whole chassis length. They are positioned close together in order to prevent vibrations during transport and under certain conditions in the field. The design also damps impacts if the driver travels over obstructions.
Model with smoothly running caterpillar drives, and steering joint:It is the special projects that create the greatest challenges for the WIKING designers. There is no doubt that one of these was the new 1:32 scale model of the John Deere 9620RX. While the miniaturisation of a tractor certainly requires many years of practised detail, together with a guarantee of precision, in this case the four drives used instead of wheels require a significantly higher level of design effort. The 620 HP crawler tractor was developed for the most demanding challenges in modern agriculture. It is understandably all about increased productivity, cost reduction, and limitation of risk. The prototype, built in Waterloo, USA, has to incorporate all these requirements. WIKING’s agricultural machinery experts have now provided fans of the precision 1:32 scale with an attractive functional model. Here, the detailed miniaturisation of the caterpillar drives which are of course completely operational, together with a combination of metal and plastic components, has created a successful WIKING model.
In addition, there is the steering joint function, which is kept mobile by means of an oscillating joint. The trailer coupling at the rear is just as detailed as the heavy bonnet made of die-cast zinc. The same is true of the two chassis components. In time-honoured fashion, the viewer can sweep his gaze over the cab interior, modelled in fine detail, and whose left hand door opens. Front, rear, and cab lighting is achieved by means of carefully inserted plastic elements. In addition, there are all-round lights, exterior mirrors, and an air intake system, as well as the exhaust and the toolbox at front left. Naturally, the rear-view mirror and the rear coupling can also be adjusted.
