The Kuhn Knight 4142 four-auger TMR mixer is designed for small to mid-sized cattle operations with features to provide reliable, efficient and affordable mixing. The unique design of our Botec mixers eliminates dead spots for consistent, thorough mixing. The efficient material flow also results in fast mixing and a quick, complete cleanout, saving you time and money. Whether you’re feeding a higher roughage dairy ration of a feedlot ration with higher levels of grain and byproducts, you can tailor your machine with features and options to best meet your needs.

The drive system, undercarriage, box construction and weight bar system have outstanding machine stands out from the competition. You get genuine quality with an innovative and streamlined design, durable components and a rugged build to help ensure reliability and long life.


Efficient Feed Movement

The raised lower right auger configuration, along with the close tolerance between the auger flighting and the auger troughs, results in a fast and complete cleanout. The offset upper right auger in combination with the raised lower auger requires less horsepower and provides a faster mix time.

Consistent Discharge

The close auger tolerances and raised lower auger design provide a fast, consistent discharge from beginning to the end of unloading. This results in even feed placement across the entire length of the bunk without a delay for mixer control. The three-auger discharge allows adjustment for feeding into higher bunks. It has a simple, hydraulic drive that provides sooth, even discharge and the augers are easy to remove for fast service.

Swivel Discharge

The versatile swivel discharge will discharge to the left, right or rear of the Primor, allowing use in difficult-to-access areas. Controlled from the tractor, bedding can be blown up to 42’ through a full 300° range.

Simplified Drive

As with the main auger drive, the discharge auger shafts are splined for a more positive power transfer and longer service life. The simplified drive design, featuring only two chains and a remote grease bank, results in easy service and maintenance.

Splined Drive Shafts

The splined shafts allow a strong, reliable torque transfer and provide easier sprocket alignment and maintenance.
