Kuhn Farm Machinery will launch a new range of large square balers at LAMMA 2020, exhibiting the SB series with increased capacity and higher density baling.
On show for the first time in the UK, the series includes the SB 890 (80 x 90cm bale size), the SB 1270X (120 x 70cm), the SB 1290 (120 x 90cm), and the extreme density SB 1290iD (120 x 90cm).
SB balers have been developed with an improved crop intake system compared with earlier models. A new crop guard design, combined with increased torque on the rotor and feeder fork driveline, gives these models up to 15% higher intake capacity and greater endurance.
The torque regulation system monitors pressure on the driveline, including the crank angle position sensor and plunger rod load pins. Picking up different pressures in the plunger cycle, the operator is guided to feed extra material into one side of the machine to achieve higher bale weights that lead to increased handling and transport efficiencies.
Machines have been designed with full accessibility for maintenance and inspection as a key consideration, and safety is given priority with features such as solid steps and a guide rail on the knotter deck. Driver comfort has been increased with upsizing of the flywheel to 485kg, so the operator will rarely feel the plunger strokes in the cab. Load sensing hydraulics are included as standard, with this system being used for axle locking, knife steering, roller cut and bale ejection. It also blasts an air stream over the knotters to keep them free from debris.
Kuhn’s widely used and proven Integral Rotor system is used on all models, ensuring optimum crop flow into the baler. All rotor types have easily replaceable Hardox tines for extended working life.
Machines are equipped as standard with a double-knotter binding system with electronic twine monitoring suitable for increased density bales.
SB 1290iD
As with the earlier LSB range, Kuhn offers the option of an extreme high density baler, with up to 25% higher bale density. The SB 1290iD provides the potential for increased handling, transport and storage efficiencies in all situations, most notably in the growing market for energy crops.
Increased bale density is possible with the same tractor power as the SB 1290 due to the innovative Twinpact double plunger system. The plunger operates with split impact, in which the bottom half of the plunger hits the bale first followed by the top half, using the full force available on each impact. This eliminates the need for an oversized driveline, flywheel or mainframe.
All SB balers are fully ISOBUS compatible with an intuitive user interface. Control is easy via the ISOBUS terminal of the tractor or via Kuhn’s CCI 50 or CCI 1200 terminals.
