Mixers Made for the
Dairy & Beef Business
of Today and Tomorrow
The Dependable Mixer
Progressive dairymen & cattle feeders know Roto-Mix delivers a quality feed mix that increases consumption and production levels. A gentle tumbling action mixes fragile flaked, leafed, and high-moisture ingredients without grinding or high pressure feed movement. This mixing action results in a fluffier, more palatable ration. The Roto-Mix design combines the gentle tumbling with quick complete mixing to save time and improve your bottom line. Roto-Mix has a complete line of mixers, and one that will meet your needs today and tomorrow.

Benefits of the Roto-Mix® Mixing System
The patented, rotor design lifts feed up to the side augers that move the feed, end-to-end for thorough mixing.
Beef Business

More Leaves — More Flakes — More Profits
Dairy Business

More Leaves — Particle Length — More Profits
Particle Protector
The Roto-Mix system protects particle length with less grinding or compaction. Fragile flakes, leaves, and other commodities maintain their nutritional value. Fast, gentle mixing also reduces the time and handling your ingredients endure before feeding that contribute to particle breakdown. More Leaves and More Flake make more Profit for you.
Fresh Fluff
Bottom line — big nutritional advantages to help you lower cost of gain. Roto-Mix consistently produces premium quality feed by lifting the ingredients past the lower auger’s wedge point, resulting in a fluffier ration that increases consumption.
Total Mixed Rations
Our thorough mixing action eliminates dead spots and corner pile—up, giving you a consistent balance of nutrients from the first pound of feed to the last. Complete mixing of ingredients also reduces the ability of the cattle to sort and “nose out” ingredients.
Flexibility
Feeds all types of grain, liquid feed, by-products, and forages. Ability to mix small and large batches with consistency, day after day, even with micro ingredients.
Forward Pitched Rotor
The patented rotor lifts feed up to the side augers that move the feed from end-to-end for thorough mixing. The lifting action of the rotor eliminates wedging of the hay or long cut feeds under the lower auger. Patented tumbling design reduces mixing power requirements.
Commercial Duty Drive Train
Splined shafts eliminate shearing of keys and gaulding of shafts. Heavy—duty chains and bearings extend life and reduce down time.
Commercial Flighting
3/4", 5/8" and 1/2" flighting available for lower auger to extend life. Top augers available in 3/8" and 1/2" flighting.
Flared Side
The flared side allows feed to tumble out of the rotor speeding up the mixing action and reducing the chance for feed to get trapped inside the rotor.
Full Scale Frame
Sturdy box frame construction with rectangular tubing for increased stability and weighing accuracy. Scale frame assembly allows scale frame to float independent of truck frame.
Commercial Scale Check System
Load cell mounting comes standard with Roto-Mix Ball and Socket type tie bars to connect the mixer to the frame. This feature eliminates side and end movement on the load cells which allow for scale dependability and accuracy.
Hay Processor
Adding hay to the ration is easy and convenient. Place the hay in the Hay Processor on the unit and let it do the work of separating the hay and distribute the long stemmed material into your mix. The result is hay, with leaves intact and the stem not continually cut up or crushed.
Shrinkage
The unique ability to process baled hay as you need it, results in less wind shrinkage when loading and processing.
Clean—Out
The forward pitch rotor design, adjustable UHMW wiper blades, and the rotation of the lower auger quickly and efficiently cleans-out the mixing chamber.
Easy Access Rear Doors
The single lever latch makes inspection easy and desirable compared to other little latches or hardware.
Single Point Grease Bank
Allows quick lubrication from a single point. Heavy—duty drive assembly runs in an enclosed oil bath.
Lower Center of Gravity
A lower center of gravity makes for a more stable unit when feeding and less shock load when cornering.
New! GeneRation II Staggered Rotor
