TO ensure full adaptability according to forage type , prevailing conditions or the pick-up width of forage harvesters and balers , the swath width can be adjusted between 1.8m and 3.6m , or the groupers can be lifted out of work to leave the cut and conditioned grass spread . When working at the headlands , one of the two conveyors making up the grouper can be operated independently with the other out of work .

The grouper attachment has been designed with a new frame and support arm configuration , when compared with earlier models , to make the overall unit more compact and stable . Significant weight saving has been achieved with the use of aluminium in the conveyor belt frames . The conveyor belts are driven by two pumps supplied by a dedicated tank integrated into the central frame , with all other operational functions

( folding , lifting / lowering at the headlands , suspension ) driven by a hydraulic unit connected to the tractor . This design avoids significant hydraulic requirements during work , eliminates over-heating and increases responsiveness of all machine functions .

Ground following accuracy and cutting precision of the mowing units is aided by KUHN ’ s Lift Control hydro-pneumatic suspension system and Optidisc cutter bars . The two rear units each have a 3.5m operating width and the front-mounted unit is 3.1m . A generous 42cm overlap on

each side ensures complete coverage when working on bends and slopes and gives an overall effective working width of 9.3m .

Pivoting steel finger conditioning units are easily adjusted to suit forage and weather conditions using two lever-controlled speeds . A transfer plate is situation between the conditioners and the conveyor belts to prevent any crop loss .

Control and monitoring of all machine functions can be carried out through an ISOBUS compatible on-board terminal or by using one of KUHN ’ s CCI 800 or CCI 1200 control units . The most common actions can also be controlled by KUHN ’ s CCI A3 joystick handle that has an integrated screen for displaying key functions . An integrated inclinometer can automatically control the conveyor belt speed according to the steepness of slopes . LED work lights are included as standard .
