AUGER & KNIVES
Our auger is the key component for producing the most uniform and consistent ration throughout the mix from bottom to top. It features an aggressive design with full flighting on a continuous curve without uneven cutouts that create inconsistent feed drops. This continuous curve provides the best lift action and ensures that once feed material is picked up it moves up in a uniform and consistent manner, rolling material back into the mix evenly and not dropping material in batches that create an uneven ration throughout.
Not only does this create a more uniform ration, it also speeds up the processing time by working harder to ensure once feed is picked up it keeps moving with maximum efficiency. Being aggressive with the design focuses on the best possible mix at the fastest possible pace with the largest possible material load, directly converting the required horsepower into the result of the mix.
To match the aggressive auger design, each auger has the capacity of up to 9 large knives, including industry exclusive carbide options designed to aggressively slice through bales and roughage.
Full Flighting – A one piece, 5/8″ thick continuous tapered flighting providing the best lift action ensuring a complete & consistent bottom to top mix of all feedstuffs. Built with mild steel for better wear resistance against acidic rations.
Multiple Knife Options:
- Tungsten – General all-purpose mixing knife
- 24″ Curved Carbide Knife – Industry exclusive carbide knife for processing bales and long stem forages and minimum wear.
- Serrated Carbide Knives – Most aggressive patented knife processes bales and roughage up to 30% faster, reducing wear.
Scraper – Ensure you get a superior consistent mix with our adjustable and replaceable scraper.
Reinforcement Plate – Add 1/2″ thick reinforcement plates to the underside of your knives.
Hard Surfacing – Increase the longevity of the auger by applying hard surfacing to the auger.
PLANETARY GEARBOX
540 or 1000 RPM Heavy Duty Multi-Stage planetary gearbox
Resistance to overloading and dissipates heat effectively
Built to handle all types of feed
Each gearbox is rigorously tested inside our facility prior to installation to ensure it meets our reliability and quality standards.
5 Year Warranty (2 Year full warranty + 3 Year Prorated)

SIDE DISCHARGE
Side Door Discharge – Unload quickly through the 43″ wide door opening. Choose between Right Side, Left Side or Double Side door opening.
Chute – All S Series mixers come equipped with a discharge chute.
Conveyor Options – Side Conveyors are offered in lengths of 3′, 4.5′, 6′, 7.5′ or 9′. (shown is a 4.5′ conveyor) Check the Specifications for conveyor reach dimensions.
Options – The Chute and Conveyors can be equipped with feed slides (steel, rubber or magnet). A Rubber Wind Guard is available for the Conveyors.
