The Kuhn Knight VTC 1120 Vertical Maxx mixers are the newest vertical, twin-auger commercial mixers that are the ideal choice for dairy and beef producers. These models have a rugged build with high-end features and are designed for commercial producers who are feeding around the clock. Improved feed movement provides a fast, complete mix for a consistent, fluffy and palatable ration. The extended-wear components of the VTC models wear less over time and provide dependable service and rugged durability. A two-speed, split planetary drive – which is the heaviest and strongest in its class – gives independent protection for each planetary, ensuring reliability and longer life. The redesigned tub allows for a lower loading height and decreased tread width, by tucking the trailer tires under the unit shell.

These models are available with a single- or tandem-axle trailer, as well as a truck mount option, and come in capacities of 800-1100 cubic feet. Trailer model specifications are listed below. For truck-mounted machine specifications, click on the “Leaflet” icon at right.


Extended-Wear Components

Extended-wear auger flighting, a heavy-duty steel floor, and standard stainless steel liners help ensure dependable service and long life, even under the heaviest use cycles.

Heavy Duty Planetary Gearboxes

The VTC planetary gearboxes are the heaviest and strongest in this mixer class and are designed to run up to 24 hours a day.

Rugged Undercarriage Options

Straight-single and walking-tandem bogie axle options are available, providing flexibility depending on terrain. Both axle systems are located under the tub for decreased tread width to keep the tires from running over the feed.

2-Speed, Split Planetary Drive

This patented drive system consist of a 2-speed splitter gearbox, two planetary gearboxes, and two torque-disconnect PTOs that provide independent protection for each planetary, ensuring reliable service and longer life.
