Kuhn Farm Machinery has extended its range of dual-purpose trailed feeder and straw blowers with the addition of two extra-wide Primor models – the 15m³ 15070 M and 4.2m³ 4270 M. The 15070 M is large enough to take up to four 1.30m x 1.20m x 2.70m rectangular bales or three round bales up to 2m in diameter. Available with a side or multidirectional discharge chute for blowing straw to the left or right, two intake rotors feed the full 1700mm width of the turbine’s input area. Capable of blowing to a distance of 18m, the turbine is fitted with eight bolt-on blades for pneumatic fodder separation.

The 15070 M uses Kuhn’s hydraulic unroll system to clamp subsequent bales in place and stop them from rotating while the first bale is being discharged, and is also equipped with an hydraulic tailgate with a 1.2t lift capacity for loading round bales. The floor of the body is fitted with a 14mm diameter chain conveyor, and an optional boost floor provides extra feed conveyor torque for the distribution of heavy products such as grass silage. Primor 15070 prices start from £34,249.

Sitting between Kuhn’s existing 3570 (3.5m³) and 5570 (5.5m³) machines, the 4270 M can take a rectangular bale up to 1.30m x 1.20m x 2.70m, or two round bales up to 2m in diameter and 1.50m wide. Fitted with an overhead chute for straw blowing and feeding: a swivelling chute is available as an option. An hydraulic tailgate with a 1.2t capacity enables self-loading of round bales, with an optional remote control allowing the tailgate to be operated without the operator having to get back into the tractor cab.

Sharing the same adjustable turbine input system as its larger counterpart, the 3570 is also equipped with the firm’s Polydrive  system and a 12mm diameter chain conveyor to feed material to the turbine. Primor 3750 prices start from £22,724.
