KUHN BTC 100 Series Botec 4-auger commercial mixers are ideal for large dairy and feedlot operations. They provide the ultimate ration flexibility to thoroughly mix a wide range of ingredients, including high percentages of byproducts or roughages. The unique Botec design eliminates dead spots for efficient material flow and fast mixing to save you time. A lower horsepower requirement, compared to competitive models, results in less fuel consumption. Multiple discharge options provide fast, even feedout and enhanced reliability from the upgraded auger drive.

Your benefits

The Botec Advantage


The Botec® Advantage

A Quality Ration and Complete Cleanout
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.

Mix Full or Partial Loads
Due to the cross-mixing action of horizontal auger mixers, Botec TMR mixers can properly mix batches that fill only a portion of the mixing tub providing you with the versatility to mix any size ration.

Even, 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 cleanout.

Competitive Mixers

Having parallel lower augers creates more force between the augers without increasing mixing capability. Parallel augers also do not transition the feed from right to left as well as if the right auger was raised. This design leads to slow, incomplete cleanout, decreases the mixer's processing ability and increases the horsepower requirements.

Rugged, Dependable Drive


Redesigned with You in Mind

The drive on the BTC 100 Series mixers has been completely redesigned from previous generations to better handle the torque experienced under the heaviest of commercial loads. This includes upgraded planetary gearboxes and a heavy-duty roller chain operating in a fully enclosed oil bath.

Splined shafts and sprockets, along with bolted auger flanges, provide a strong connection and positive power transfer. Heavy-duty bearings are mounted on the outside of the mixing chamber for easy service and long life.

Easy Access Door

The single-handled latch provides easy access to the oil bath. An improved seal keeps oil in, and dirt and debris out, to help minimize wear on drive components and maintain a cleaner appearance.

Enhanced Drive Serviceability

The flanged and bolted augers provide a stronger auger to drive shaft connection. Splined shafts give more positive power transfer and longer service life compared to keyed sprocket-to-shaft connections.

Tailor Your Machine


Auger Options to Meet Your Ration’s Needs

The grain-auger option provides gentle handling of more delicate feeds like flaked corn to maintain ration quality and prevent fines.
The roughage-auger option features notched, sectional flighting with welded-in, self-sharpening, hardened knives for better hay handling.  
With the Roughage Maxx® system, scalloped knives are added to the lower augers to maximize hay processing. The knives provide a more consistent particle length and more even blending. The result is a more uniform and palatable ration with reduced sorting for improved feed efficiency.

Multiple Discharge Options

To best suit your feeding needs, you can choose from a slide tray, chain and slat conveyor, 3-auger discharge or a 4-auger discharge to be equipped on your BTC 100 Series mixer.

Slide Tray

The side discharge slide tray has simple hydraulic controls and helps guide feed further away from the tire path. Magnets are standard on slide tray.

Chain and Slat Conveyor

Rugged chain and slat conveyor options provide the ultimate in durability and long life. Heavy-duty components ensure reliable service and multiple conveyor length options offer unmatched flexibility to match different feeding situations.

3-Auger Discharge

The 3-auger discharge allows adjustment for feeding into higher bunks. It has a simple, hydraulic drive that provides smooth, even discharge. Long lasting, poly chute liners help prevent rust and limit wear. The 3-auger discharge comes standard with fixed tip-off and built-in magnets.

4-Auger Discharge

Center-rotating augers bring the feed to the center of the discharge to increase overall capacity and provide a smooth, even discharge for all ration types. The 4-auger discharge comes standard with power tip-off and built-in magnets. The discharge augers are simple to remove for easy service. Long-lasting, replaceable polyethylene chute liners prevent rust and limit wear. 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 in easy service and maintenance.

Trailer & Truck Models

To suit your operation’s needs, KUHN Knight BTC 100 Series mixers are available in a trailer or truck-mounted configuration. Trailer models are the most popular configuration as they are the most economical and versatile. Being detachable allows the tractor to be used elsewhere on the farm when not in use for feeding. Truck-mounted models are a suitable option for those that have to feed cows at several different locations, with large travel distances. This option allows a feeder to quickly get from the mixing location to the feed bunk and back again.
