Designed for low horse powered tractors!

PRIMOR 3570 M trailed all-fodder straw bedder and feeder, with the POLYDRIVE system and a capacity of 3.5 m3

Find a distributor near you

The PRIMOR 3570 M has been designed and developed for farmers looking for a 3.5 m3 straw bedder and feeder compatible with 50 HP tractors (70 HP for haylage bales).

Thanks to its large capacity, the PRIMOR 3570 M cuts down on handling times: 1 bale with a diameter of 2.00 metres, and 2 of up to 1.5 m in diameter. The machine can easily accommodate square bales of up to 2.7 m in length.

The adjustable regulating tines come as standard, allowing the machine to adapt to the properties of the feed by modulating the action of the separating system.

Your benefits

Distribution of all types of forage

The PRIMOR 3570 M straw bedder and feeder is fitted with our patented POLYDRIVE system, combining the power of a mechanical drive system with the flexibility of a hydraulic solution for hassle-free distribution of even the longest fibres.

POLYDRIVE feed rotor drive

With the POLYDRIVE patented system, the feed rotor benefits from the power generated by the turbine flywheel. Distribution of long-fibre forage is no longer a chore.

With a drive belt that can be disengaged as required via the electric controls in the tractor cab, you can cut the forage flow when obstacles are encountered along the feed passage (posts, drinking troughs, passing farm workers, etc.).

All it takes is 2.5 minutes to distribute a 1.4 m bale of haylage!

All-fodder type feed rotor

The PRIMOR 3570 M straw bedder & feeder is equipped with an all-fodder feed rotor, with sections mounted on a series of 8 discs in order to maintain the structural integrity of silage and similar foodstuffs (no 'milling’ effect).

The regulating tines ensure a regular flow of feed into the turbine, shaped and positioned to distribute the fodder along the whole length of the separator.

Continuous adjustment!

The PRIMOR 3570 M is equipped with an adjustrable regulating system. With 3 preset positions and an optional hydraulic adjustment system, this set of regulating tines is key to the machine’s superior flexibility.

For difficult foodstuffs (long fibres and haylage bales), the low positioning of the boom prevents forage from getting into the turbine. The fibres are thus effectively and evenly distributed.

When it comes to bedding, the quality of the straw is key! That’s why setting the tines to the raised position allows you to increase the flow of straw into the turbine. Flattening is kept to a minimum.

For silage feeding

For farmers working with silage, an optional slide directly aligned with the turbine ensures that the product is redirected as soon as it leaves the chute, for clean swath distribution.

The wide opening ensures there is no risk of blockage when working with long-fibre fodders. Manual installation.

The length of the outflow pipe can be adapted to the tractor track.
Because the chute is fully aligned with the turbine, the PRIMOR 3570 M is suitable for silage distribution

High quality straw bedding, for the comfort of your animals

Regular, even quantity of straw per m3

The turbine wheel is composed of 8 bolted-on blades, 2 of which are slightly longer, in order to vary the rate of flow of straw into the turbine and create a shower effect.

The large surface area of the blades ensures that the fodder is propelled all the way up the chute. The result is regular, constant straw distribution throughout the whole space, with no need to shift the chute cap upwards.

KUHN, the leading name in straw blowing!

The 150 mm space between the blades and the turbine inflow is what we call the “pneumatic separation chamber.”

The volume of air moving through this chamber draws the feed while also gently untangling it. The straw thus remains intact. The result is a litter which is more resistant and longer-lasting, delivering greater comfort for your animals!

Everyday comfort

Ergonomic electric controls for comfortable use of the KUHN PRIMOR 3570 M straw blower & feeder day after day

Electric controls as standard

The electric controls ensure a smooth user experience. The compact control panel has been designed to fit inside all types of tractor cabs.

Enjoy full access to all the functions of your machine without leaving the driver's seat.

The only operation requiring a remote control cable is changing the turbine speed (310 and 620 min-1).

Combined on a single control pad, you can change the direction of the chute and adjust the chute cap with one hand!

The machine is easy to load

The gently-sloping tailgate is flush with the conveyor belt, facilitating the loading of round bales.

The tub fitted to the PRIMOR 3570 M has been designed to handle round (1 round bale up to 2 m in diameter) and cubic (1 cubic bale up to 2.7 m in length) bales of all sizes.

In emergency situations, the PRIMOR 3570 M can also be used to distribute grass and corn-based silage.

Designed to last!

PRIMOR straw-blowers & feeders are designed for simple maintenance.

The belt is a self-contained sub-unit, bolted to the tub body. The belt will last for many years, and can then be easily changed. In order to keep the belt clean, it is fitted with an integrated evacuation hatch as standard: no more
build-up at the bottom of the belt.

The cast iron sprockets and marine-grade chain ensure that the belt remains perfectly aligned.
