Why Choose A Primor?

Ultimate Versatility

The KUHN Primor machines can process a wide variety of materials that can be used in a multitude of ways. Both round and square bales of a wide range of sizes can be processed for both bedding materials or feed ingredients. Materials from corn stalks to wheat straw, and even to grassy hay can be processed using the multi-function rotor. Processed materials can then be dropped into a feed bunk, blown into a pile, or evenly spread throughout a pen.

Labor Savings

One person can quickly and easily bed multiple pens in a shorter amount of time.


Increased blower thickness and the hydraulically disengage-able Polydrive® belt system provide greater longevity and little maintenance.


Use fewer materials due to a better and more even distribution. Using a Primor also results in lower costs and lower horsepower than a tub grinder.

Operator Comfort & Safety

The tractor-mounted control box provides easy operation and adjustments directly from the cab. Safely bed pens evenly and efficiently without having to enter the pen.
