KUHN’s new mounted mower conditioner combination, the FC 9330 RA, is fully integrated with swath grouping units capable of delivering the machine’s 9.3 metre cut into one swath in a single pass.
Adaptable 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.
When compared with earlier models, the grouper attachment has been designed with a new frame and support arm configuration to make the overall unit more compact and stable whilst 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.
