​CLAAS presents new-generation ORBIS

The new ORBIS 600 SD and ORBIS 750 maize front attachments feature both large and small discs for an optimal crop flow, high efficiency and functional reliability. The tilting frame concept with newly designed T-panels reduces the weight and increases the wear-resistance. And with the new folding system, the front attachments are ready for use in a matter of seconds.

The concept of the new ORBIS maize front attachments, which are available in working widths of 6.0 m and 7.5 m, is based on the proven combination of large and small discs. Large discs are fitted in the central area of the front attachment. These ensure a smooth crop flow and have significant functional advantages during reversing. On the ORBIS 600 SD, the outer units have two small discs (SD = Small Disc) while the ORBIS 750 is equipped with a combination of a large outer disc and a small inner disc. As a result, both models have the proven V-shaped crop flow with optimal functional reliability, even where the density of the maize stands varies.

The newly designed fingers ahead of the knives ensure low-loss crop collection and feature points which can be removed for harvesting laid maize. The knives with their new crescent-shaped blade deliver top cutting quality in all crops.

Tilting frame with T-panels
The new tilting frame concept ensures a centred feed of the crop to the JAGUAR's precompression rollers. This robust component has been optimised to handle the weight of the front attachment and the forces generated by it. Depending on the field conditions, the mounting angle of the tilting frame can be set to two different positions. The advantage of this arrangement, especially in wet conditions, is that the cutting angle of the front attachment can be maintained despite the front wheels of the forage harvester sinking into the soil to a greater extent. AUTO CONTOUR provides active control of the lateral compensation and ensures a precise stubble height across the entire working width. This system is standard for the ORBIS 750 and available as an option for the ORBIS 600 SD model.

Newly designed, modular T-panels support the drive train and the discs. In combination with the new frame design they enable a low and even cut without dirt adhesion. The T-panels are press-hardened and rounded, dimensionally stable, wear-resistant and protect the transmission elements against wear and structural loads.

New folding system: ready in next to no time
Both models have been equipped with an all-new folding concept which has been developed with the goal of reducing folding times significantly in order to keep setup times to a minimum. On the ORBIS 600 SD, the side units fold equally to the centre while those of the ORBIS 750 overlap each other symmetrically. This compact folding system offers the operator an optimal view for on-road travel. Both models have a transport width of 3.0 m, a factor which simplifies licensing.

Both models are available with an integrated transport system to enable them to be licensed for on-road use. The system is operated from the cab. Once the transport system has been activated, two wheels on the road bear the main load of the front attachment in order to comply with the permissible front axle loads of the JAGUAR. An integrated vibration damping system ensures smooth, comfortable on-road travel at up to 40 km /h. The system enables fast, safe movement between fields and avoids unnecessary setup procedures.

Drive concept for perfect chop quality
The drive concept is matched perfectly to both the JAGUAR 900, including the variable front attachment drive, and the JAGUAR 800, and ensures perfect chop quality. A two-speed gearbox is used to adjust the overall speed of the maize front attachments while a three-speed gearbox controlling the feed drums makes for perfect coordination of the crop flow. An automatic function for the variable front attachment drive allows the crop flow to be optimised conveniently from the cab.

The low number of gear units and the effective power transmission keep the power requirements low and maximise efficiency. And in a positive development with regard to maintenance costs, it has been possible to extend the oil change intervals to 2,500 hours or 5 years.

Every ORBIS is equipped as standard with a communication module which transmits data from the front attachment to the forage harvester and saves JAGUAR settings. Even after a change of front attachment, the settings are not lost, a feature which saves time and avoids operating errors.
