KUHN Knight VSL 200 Series Vertical Maxx® single-auger mixers are designed for small- to mid-sized dairy and beef producers. Two models, ranging from 420 to 550 cubic foot capacities (with extensions), offer the versatility of front, side or rear door unloading. The low-profile design is perfect for quick and easy loading. The proven cone-auger design reduces horsepower requirements, results in more efficient movement of feed and enhances final cleanoff of the auger when unloading.

Superior Feed Movement

Cone-Style Auger & Kicker Design

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 straight 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

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.

Large Discharge Doors

For unmatched feed flow, these mixers feature a large discharge door. The large openings also help ensure less binding in high hay rations, especially when discharging high-roughage rations. Upgrades to the door pivot linkage allow for smooth operation of the door.

Low-Profile, Heavy-Duty Design

Low-Profile Design

Easily loaded with a skidsteer, the low-profile design of the VSL remains a hallmark feature. Choose a VSL where low loading height or low clearance in entrances to buildings is desired.

Heavy-Duty Single-Axle Undercarriage

The single axle, dual-wheel design allows for ease of maneuverability, reduced ground pressure and overall stability. Both implement and truck tires are available.

Heavy-Duty Front, Side and Rear Doors

VSL 200 Series mixers feature heavily reinforced doors for tight closure and long service life. The hydraulically activated door linkage reduces the overall height of the mixer to allow clearance in barns with rafter/door limitations. It also allows for faster unloading as a result of a higher door opening height than would be possible with straight pulled doors.

Fully Welded Tub Design

The completely welded body provides superior strength and durability for long life without cracking at bolted joints. The heavy-duty, reinforced floor and body help ensure dependable service and long life.

Dependable Drive Design

Simple, Dependable Drive

A planetary drive system provides simplicity for long life and heavy-duty use. The flooded top bearing eliminates the need for extra grease zerks. This proven and rugged drive system, coupled with an external oil reservoir, is virtually maintenance free, with the exception of scheduled gear lube changes.

Two-Speed Gearbox

A shiftable, 2-speed gearbox option allows for reduced input horsepower and auger speed for easier starting and mixing, even with smaller tractors. The gearbox can be shifted manually on the machine, or with an in-cab electric shift option for operator convenience.

Shear Bolt Overload Protection

The planetary gearbox is protected by a shear bolt from overload and torque spikes caused by obstructions.

Equipment

Hay-Retention Ring

The steel hay-retention ring helps contain large round bales during processing and reduces hay spillage more effectively compared to similar options on competitive models.

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.

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.

Slide Tray

The side-discharge slide tray on the VSL & VT models has simple hydraulic controls and helps guide the feed further away from the tire path. Discharge magnets help catch metal fragments to prevent hardware.

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.

Side Chain & Slat Conveyor

Optional side conveyors provide the ultimate in durability and long life. Heavy-duty components ensure reliable service, even in extreme use conditions. Multiple conveyor length options offer unmatched flexibility to tailor the discharge to your needs. A fixed tip-off with magnets can be added to catch small metal fragments present in the feed and help prevent hardware disease.

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.
