The new Claas Orbis 600 SD and Orbis 750 maize front attachments promise to deliver optimal crop flow, high efficiency, and functional reliability
Available from later this year, the new Claas Orbis 600 SD and Orbis 750 maize front attachments in working widths of six and 7.5 metres promise to deliver optimal crop flow, high efficiency, and functional reliability.
Claas Harvest Centre product manager (Claas Jaguar) Luke Wheeler says the new fronts are based on the proven combination of large and small discs.
The new models feature a new folding system for rapid set-up and transport. On the Orbis 600 SD, the side units fold equally to the centre, while the panels on the Orbis 750 overlap each other symmetrically.
The new folding system means both front attachments are ready for use or transport in a matter of seconds. With a maximum transport width of three metres, they can be easily transported by road.
Both models have the V-shaped crop flow for optimal reliability, even in variable harvesting conditions. The newly-designed fingers ahead of the knives reduce crop loss and feature points, which can be removed for harvesting laid maize. New crescent-shaped knife blades deliver top cutting quality.
The new tilting frame concept (standard for the Orbis 750 and optional for the Orbis 600 SD model) ensures a centred feed of the crop to the Jaguar’s pre-compression rollers.
“This robust component has been optimised to handle the weight of the front attachment and the forces generated by it,” Luke says.
Auto Contour provides active control of the lateral compensation and ensures a precise stubble height across the entire working width, while newly-designed, modular T-panels support the drive train and the discs. The drive concept is matched perfectly to both the Jaguar 900 and 800 series to ensure perfect chop quality and crop flow.
“A two-speed gearbox governs the speed of the front attachments while a three-speed gearbox governs speed of the feed drums,” Luke says. The low number of gear units and the effective power transmission keep the power requirements low and maximise efficiency.
“Performance aside, these improvements have extended the oil change intervals to 2500 hours or five years.” Orbis front are equipped with a communication module that transmits data from the front attachment to the forage harvester and saves corresponding settings on the forage harvester.
“Even after a change of front attachment, the settings are not lost, a feature that saves time and avoids operating errors,” Luke says. New Claas Orbis 600 SD and Orbis 750 maize front attachments will be available from spring 2019.
