For this reason, the choice is for versatile machines that handle products that are difficult to move during deliveryhigh speed of distribution of the crushed product is decisive. In addition, the close relationship between production quality and animal welfare. Adopting solutions that increase it is a crucial step towards improvement sustainability of livestock farming. Here again, the right machine can make all the difference.

KUHN offers a range Primor straw blowerssuitable for all kinds of fodderable to respond to the various needs that the farm encounters on its way, among them we find:

  • Primor 2060 HSM: in supported and semi-supported version with a volume of 2 cubic meters;
  • Primor 3570M and 5570Mequipped with the Polydrive distribution system, they have a capacity of 3.5 and 5.5 cubic meters;
  • Primor 4260 M Cut Control, adds an independent cutting system for a capacity of 4.2 cubic meters. From the driver’s seat, the operator can adjust the eight turbine blades equipped with 5 and 6 alternating blades determining cut length according to your needs.

Primor 15070 M: high-capacity flagship

But it’s onthe Gamma flagship which we focus on. Primor 15070 M has features common to most other Primor models, but can handle up to 3 x 2.2 meter round bales on average or up to 4 rectangular packages of 2.7 meters each. The model is available with patented system Unwind (optional) that locks the second package in the container while the first is distributed.

WITH grass or silage corn, Primor 15070 M has a effective capacity of 15 cubic meters. The machine is suitable for all types of forage and can be filled with a top loader as well as a hole rear hatch which descends to ground level.

Dust? Animal welfare guaranteed with CleanStraw

The presence of dust in living spaces is dangerous comfort of farm animalsbut also well-being and the health of farmers. This can negatively affect productivity with consequences for the company’s economy: up to 20% lower growth and fattening.

Pure straw it is a device that splash water in the straw stream during the distribution stages, which allows accelerate dust deposition from the first 30 seconds.

Straw retains its absorbent properties because the operation requires a limited amount of water: 3 liters per 100 kilograms of straw. From a technical point of view, the machine uses a 64 liter tank forworking autonomy between 12 and 18 packages.

The system, which can be activated via an electric control unit in the cab, is linked to the transmission and starts when the straw blower is started. CleanStraw is available in the entire range straw blowers and Primor mixing wagons with the system Profile Plus thatching.

Advantages? Improve livestock health Thanks reduction of possible mycotoxins in the air, greater daily comfort for farmers and preserved straw absorbent properties. The end result is cleaner stables and guaranteed well-being of animals.

Maximum security with the Polydrive system

Primor 15070 M is supplied as standard Polydrive gearboxwhich is a feature common to the entire range, except for the Primor 2060 version.

Two rotors mechanically controlled power supplies provide a even flow in the turbine thanks to their concentric screws. Depending on the type of forage, the flow rate and cutting force are hydraulically regulated.

Power rotors can be disconnected at any time thanks to the Polydrive: one system unfastened belt which connects the rotors to the turbine. The switch automatically stops the conveyor feed when the feed rotors are disengaged to guarantee total construction site safety work.

Boost Floor for finely regulated distribution

Thanks electric control supplied as standard, Primor 15070 M has two speed ranges conveyor aa potentiometer for settings in each range.

• V Slow mode two hydraulic motors on both sides of the conveyor work together. Cumulative displacement two engines, that is, for the same hydraulic flow, the conveyor moves slower but has a much higher torque (crankshaft torque: 8,520 Nm). System Boost Floor it allows the conveyor to move smoothly, without interruption, with a workload that can exceed 8 tons, as in the case of delivering large quantities of silage.

• V Fast mode it works only hydromotor and the conveyor moves much more fast. This mode is suitable for straw distribution, the performance of which with the Primor 15070 M is remarkable.
