KUHN VT 280 & VT 2100 twin-auger Vertical Maxx mixers are ideal for large dairy and beef producers who want to place quality rations in front of their animals. The VT models are rugged, dependable, large-capacity mixers designed for moderate-use cycles of around 4 to 5 hours per day.

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. The VT Series trailed mixers are available with a single- or tandem-axle trailer to best match customer needs.

Superior Feed Movement

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.

A: Knife set in for slicing and cutting
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

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

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.

Equipment

Capacity Belt Extension

A belt extension, added to the top of the mixing tub, increases capacity by about 10%. It also improves hay containment, and rubber construction is durable and pliable for long life.

Viewing Platform

All models feature a standard observation ladder to easily view the inside of the mixing chamber. Front door, trailer models also offer an optional viewing platform for a convenient, comfortable place to check mixing progress.

High-Wear Components

Optional DuraMix^® hardened auger flighting provides enhanced wear resistance and longer auger life in the toughest conditions. The flighting is made of high-carbon steel throughout, with hardened outer edges for unmatched durability. Optional 30”, stainless steel side and baffle liners provide extra protection in the lower part of the chamber where most wear occurs.

Flat Chain & Slat Front Conveyor – Front

The flat, front conveyor option is simple to operate and offers convenient feeding from either side of the machine on trailer models. Hydraulic side shift is standard and gives you the ability to shift the conveyor a total of 16” from side to side for accurate feed placement.

Either or both ends of the flat conveyor can be fitted with a hanging belt with magnets to catch small metal fragments. The hanging belt also helps to even feed flow off the end of the conveyor. A fixed tip-off, with magnets, can be added to catch small metal fragments present in the feed and help prevent hardware disease.

Incline Chain & Slat Conveyor – Front

The incline conveyor option is available with the choice of either right or left side unloading on trailer models. This option allows the flexibility for both floor feeding and feeding into bunks of various heights where a longer or higher reach is needed for precise feed placement. A fixed tip-off, with magnets, can be added. The magnets work to catch small metal fragments present in the feed and help prevent hardware disease.

Side Belt Conveyor

An optional belt conveyor can be added for easy and consistent placement of feed at varying heights including the filling of mobile feed carts. The belt offers quiet operation and consistent feed flow. Belt conveyors are able to run steeper versus a chain and slat because you can run the conveyor faster, depending on the materials. The low profile sides allow the conveyor to fold up tighter to the machine for a more narrow transport width. An optional deflector helps with placement of the feed and provides an option for magnets.

Slide Tray

The high discharge point of the Reel mixers allows use of the simple, dependable, low-cost slide tray in most applications. It has simple hydraulic controls and the long discharge tray reaches deeper into bunks to prevent feed loss from the wind. Magnets are standard on slide tray.

Scale Systems

Different scale brands, models and option are available for all types of operations, ranging from basic to high-end feed-tracking programs. Optional remote indicators are available for placement that will allow easier viewing.

5-Year Warranty

KUHN offers a 5-year prorated warranty on planetary and 2-speed gearboxes on all vertical mixers. KUHN also offers a 1-year warranty on all other machine components.
