FOUR NEW models have been added by Kuhn to its range of VB variable chamber round balers.

The VB 3160 and VB 3165 (1.2 x 0.8 x 1.6m bales), and the VB 3190 and VB 3195 (1.2 x 0.8 x 1.85m bales) can have net or twine binding.

All have Kuhn's progressive density baling chambers which use two chamber rollers, a starter roller and five endless baling belts to produce the bales. Belt pressure increases as the bale grows and can be adjusted from the tractor cab to compensate for variations in crop type or quality and to maintain a constant bale density.

Both the VB 3160 and VB 3190 can come with Optiflow, Optifeed or Opticut 14 intake rotors, while the 3165 and 3195 machines get the choice of the Opticut 23 intake rotors, but lose the Optiflow version.

Optiflow uses a 2.1m pick-up and non-restricted, open throat intake rotor for handling heavy crops, while Optifeed models have a wider 2.3m pick-up and patented integral rotor and side augers to achieve a high input capacity from a reduced power requirement.

The Opticut 14's 2.3m pick-up has an integral cutting rotor with 14 knives, while the Opticut 23's additional knives give more of a chop to the crop.

All have Kuhn’s dropfloor and hydraulic rotor disengagement system to clear blockages.

The latest VB balers are driven by just three main chains, each of which are designed to have a low maintenance requirement and can have optional automatic chain lubrication.

All can also have ISOBUS control, from either a 5.4-inch or 12.1-inch screen and the layout display can be configured to suit individual operator’s preferences or machine’s requirements. A split-screen function enables the operator to view and control two machines in tandem.
