The new Orbis 900 header from Claas will be available for the 2021 maize harvest.

Ready for the 2021 season, Claas has renewed the top-of-the-range model in its line-up of Orbis row-independent front attachments for the Jaguar. Stand-out features include a transport width of only 3m and new, automatically folding transport protection with integrated lighting.

As with the Orbis 750, the frame of the Orbis 900 consists of five parts. This makes it unrivalled for fast folding and enables an extremely compact, road-travel-friendly design without compromising visibility to the front or sides to any significant degree. As a result of the new transport width of just 3m, and thanks to the outstanding visibility, a transport speed of 40km/hr can be maintained safely.

The transport width of the new Orbis 900 header is only 3m.

During folding/unfolding, the optional fully integrated transport protection with warning stickers and lighting automatically pivots into the appropriate position for road travel or field work. The entire folding process takes only 30 seconds and does not even require the operator to get down from the cab. This cuts transit and setup times considerably and reduces the operator’s workload during transfers. At speeds between 2.0 and 7.0km/hr, a touch of a button is all that’s required to start the automatic folding process. With the front attachment in working position, the transport protection remains safely out of the way in its parking position.

In order not to exceed a drive-axle load of 11.5t, an integrated transport system is available. This is deployed automatically when road travel mode or oscillation damping is activated. Attaching the 8.93m wide Orbis 900 is also child’s play. Front attachment detection and automatic drive coupling ensure that no valuable harvesting time is wasted here either.

The flat mounting angle with two different positions and the very flat design make it possible to attain stubble heights as low as 85mm. Large discs immediately ahead of the feeder unit ensure that even large crop volumes can be handled reliably. Paddles and cob retainers always ensure that cobs that have fallen down are also transported to the feeder unit.

Transport wheels ensure the front axle load weight remains legal on the road.

As before, the guide strips in the high-wear areas can be replaced easily. Instead of the standard crop-flow components, wear-resistant Premium Line versions can be specified as an option. The latter comprise guide strips in steel, feeder drums with an additional coating and particularly wear-resistant knives with the proven, reliable crescent shape. The modular design of the drums makes repairs easy.

The V-shaped, energy-saving crop transport system is supported by two feeder cones on the impellers on each side. Feeder drums with three speed adjustment settings handle the safe, longitudinal transfer of the crop to the feeder unit. When lodged maize is to be harvested, side covers with a hydraulically driven lodged maize auger as well as lodged maize cones for the outer transport discs, an extended centre point and point extensions are available. Optional guide bracket extensions can be fitted when working in very tall maize.

The two-speed main gearbox makes it easy to adjust the speed of the cutting drums to different operating conditions, and the three speed feeder cone gearbox allows speed adjustment to suit different chop lengths. Where the forage harvester has a variable front attachment drive, the first speed is always used. The gearboxes operate at low revs and therefore reduce wear. Furthermore, all drives have comprehensive overload protection.

The five-section Claas Orbis 900 header folds in just 30 seconds.

Despite its large working width, the Orbis 900 is able to follow the ground contours optimally. This is made possible by the new tilting frame with a +/- five-degree tilt correction in combination with Auto Contour hydraulic swing movement compensation. In addition to the two standard sensor bands at the outer edges, a third, centrally fitted sensor band is available as an option. This provides a further noticeable enhancement of the ground contour following performance, especially on uneven ground. The long, spring-loaded sensor bands ensure reliable front attachment guidance, whatever the ground characteristics.
