These mixers feature a proven mixer tub and auger design, ensuring a quality mix is delivered, every load. The VT 280 and VT 2100 mixers are a great choice for operations looking to minimize feeding time and are competitively priced for moderate feeding situations. Multiple door location options for both models offer versatility for different feeding situations and provide fast, consistent discharge.

Your benefits

Superior Feed Movement

VTC200_Auger.png

Cone-Style Auger & Kicker Design

New cone-style augers provide superior feed movement for faster, more complete mixing and processing. The smooth, continuous auger flighting (1) creates a rolling feed action that improves mixing. The top cover of the auger has a steep angle to aid in bale movement when processing round bales and to prevent feed from sitting on top of the auger between mixes. The swept back bolt-on kicker (2) provides a fast and even discharge. Each lead flight is equipped with a cast iron scraper (3) that pulls material away from the tub walls into the auger for a better overall mix. Both the kicker and scraper are bolt-on attachments, making replacement very easy to save you precious time.

Hardened Knives

Large, 15” or 20”, replaceable hay cutting knives are available to best handle the material to be processed. The knives have two positions to adjust the aggressiveness of the knife angle. Versatility of knife length, angle and position allow for an optimal setting with a wide variety of ration ingredients.

  • B: Knife set out for grabbing and tearing

Efficient Mixing Chamber

Straighter sides, smoother curves and steeper baffles help promote a fast, complete mix for a fluffy, palatable ration. No preprocessing or special loading is required for round or square bales making it easy to load and use. Faster auger speeds also provide quicker, more complete cleanout.

Large Unloading Doors

For unmatched feed flow, these mixers feature the largest discharge door available in the industry. The discharge linkage allows for rapid opening and closing of the door.

Adjustable Hay Stops

The adjustable hay stops provide flexibility in processing to provide you with the cut length necessary to reach the optimal nutritional value you’re striving for. This adjustability makes hay processing more efficient and helps minimize overprocessing.

Simple, Dependable Drive

VT_SplitDrive.png

Patented 2-Speed, Split Drive

The patented drive system on the VT 280 and 2100 mixers consists of a 2-speed, split-drive gearbox, two planetary gearboxes and two torque-disconnect PTOs. This system provides reliable performance and long service life with a simple and quiet design. Truck and trailer models only. 

The 2-speed, split-drive gearbox provides the flexibility of high and low speeds without adding another gearbox. It allows for a lower horsepower and easier starting speed (28 rpm in low) while also having a high speed for fast mixing and more complete cleanout (41 rpm in high). The gearbox can be shifted manually on the machine or with an in-cab electric shift option for operator convenience.

Heavy-Duty Gearboxes

The twin planetaries are designed to provide dependable performance and long life. The drive systems allow the use of single-stage planetaries, which produces far less heat for easier cooling.

Torque-Disconnect PTOs

Two automatically resetting torque-disconnect PTOs provide independent protection for each planetary. This helps guard against obstructions encountered by each individual auger, ensuring reliable service and longer life.

Easy Accessibility

Easily pull the planetary from the top of the mixer for improved and easier service.  The image shown is from a KUHN Knight VTC model.

Multiple Configurations

VT256_DoorLocations.png

Multiple Door Options

Various door configuration options on trailed and stationary models offer flexibility to fit a variety of feeding situations. The large discharge openings provide fast, even unloading from front, side and rear door locations for maximum efficiency.

Choose a front door for clear visibility of the material coming out of the door. The front cross conveyor uses rugged components for unmatched dependability. A heavy-duty, steel floor, along with the heaviest conveyor chain in the industry, helps ensure long life and less down time. New discharge options provide the ultimate in versatility to match most feeding situations.  

VT 280/2100 models offer doors on either or both sides. The large openings allow fast unloading with comparable feed flow out of one door that many competitive machines get with two.

A rear commodity door is available. The large opening provides fast discharge, even with high-roughage premixes. A discharge tray is included on truck models to direct material flow for clean, accurate feed placement.
