The ability to chop and distribute straw or big bale silage of varying consistency and quality is enhanced in the latest model to be added to Kuhn’s Primor feeder/bedder range.
The trailed Primor 3570 has a 3 cubic metre capacity, so will carry two 1.5m diameter round bales, and is capable of feeding any long fibre forage and distributing bedding straw up to a distance of 18 metres through a single top chute.
Like the 5.5 cubic metre capacity Primor 5570 model launched last year, the 3570 is fitted with a hydraulically-operated regulator at the entrance to the feed rotor. This allows throughput to be adjusted according to material quality, therefore maintaining operating efficiency under varying conditions.
Key to the Primor’s ability to chop and distribute straw and silage is a robust two-speed gearbox. This is typically operated at its lower rate mainly for silage and at the faster rate when distributing straw. Power is transmitted from the gearbox through a shaft, which in turn drives a four-strand power-band system, which is engaged/disengaged using a hydraulic cylinder. The power band is significant, as it provides high horse power transmission to the distribution beater rotor, whilst also acting as a safety device.
The bed chain conveyor operates independently to draw material into the beater rotor. This can be operated at varying speeds, and put into reverse, to control the flow of material into the distribution area.
Distribution of forage for feeding or straw for bedding is through the same top chute, which is height adjustable. There is also the option of a 300 degrees swivelling chute for greater accessibility in restricted spaces.
The rear door of the Primor 3570 is hydraulically controlled, allowing self-loading if required. All functions are controlled electronically from the tractor cab.
Kuhn recommends a minimum tractor power requirement of 70hp when the Primor 3570 is used for silage or haylage type forages. The standard Primor 3570 comes with electric controls and costs £15,430. The 300 degrees swivelling chute costs an additional £555.
