KUHN Farm Machinery has extended its range of dual-purpose trailed feeder and straw blowers with the addition of two extra-wide models. The 15m3 PRIMOR 15070 M and 4.2m3 PRIMOR 4270 M both boast extra-wide, high-capacity bodies enabling them to handle the largest of round and square bales.
PRIMOR 15070 M
The PRIMOR 15070 M is large enough to take up to four 1.30 x 1.20 x 2.70 metre rectangular bales or three round bales up to 2 metres in diameter. It can be customised according to the layout of farm buildings, with a side or multidirectional discharge chute (GL model variant) enabling straw to be blown to the left or right.
Performance has been a key focus throughout the development of the new machine, with two powerful intake rotors feeding the full 1700mm width of the turbine’s input area. A bank of six hydraulic tines above the feed rotors enables intake settings to be adjusted and regulated according to the type of product being used and to feed the turbine with an even supply of material. The turbine itself is capable of blowing to a distance of 18 metres and is fitted with eight bolt-on blades for pneumatic fodder separation.
The PRIMOR 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. It is also equipped with an hydraulic tailgate with a 1.2 tonne lifting capacity for loading round bales. The floor of the body is fitted with a 14mm diameter chain conveyor with an optional boost floor available to provide extra feed conveyor torque for the distribution of heavy products such as grass silage.
In common with existing machines in the PRIMOR range, the 15070 M uses KUHN’s disengageable belt driven POLYDRIVE clutch system to drive two feed rotors which are equipped with 30 cutting sections for ultimate control over cutting length and intensity: all PRIMOR machines are capable of feeding all types of long-strand feedstuffs including straw, silage and haylage.
Starting price for the basic machine (with side chute and electric control) is £34,249.

PRIMOR 4270 M
The PRIMOR 4270 M has a 4.2m3 capacity enabling it to take a rectangular bale up to 1.30 x 1.20 x 2.70 m, or two round bales up to 2m in diameter and 1.50m wide. Equipped as standard with intuitive electric controls, the PRIMOR 4270 M is simple to operate.
The smaller of the two new models sits between KUHN’s existing 3570 (3.5m3) and 5570 (5.5m3) machines and is fitted with an overhead chute for straw blowing and feeding: a swivelling chute is available as an option. An hydraulic tailgate with a 1.2 tonne 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.
The PRIMOR 4270 M shares the same powerful and adjustable turbine input system as its larger counterpart, and is also equipped with KUHN’s POLYDRIVE system and a 12mm diameter chain conveyor to feed material to the turbine. Other features include a stainless steel lower turbine housing to prevent corrosion by silage effluent.
Starting price for the basic machine (overhead chute) is £22,724.
