KUHN Knight RA 136 & 142 Reel Auggie^®mixers provide outstanding durability and performance, with advanced features that stand out from the competition. Reel mixers are ideal for dairy and beef producers mixing rations with high percentages of processed roughages or distillers grains. The Helix^® reel, with its open-concept design, offers faster, more consistent mixing and improved load leveling with any ration. Strengthened body and drive components provide superior dependability and long life. From the popular, multi-purpose trailer models, to the fast, convenient transport offered by truck mounted machines, to stationary models that are ideal for central mixing, there is a mixer to meet the needs of any operation. These machines also offer a low standard loading height for easy loading with skid steers.

The Reel Advantage

Superior Feed Movement

The reel thoroughly mixes rations gently without causing excessive damage to the feed ingredients, providing desired particle length in the TMR. The large reel gently lifts material up into the side augers for excellent side-to-side movement. The upper auger moves material rearward, while the lower auger moves material forward for end-to-end mixing. This helps feed continually charge the door during discharge.

The Unique Helix^® Reel

The Helix^® reel has a robust build and has been thoroughly tested to withstand the most challenging conditions. The design of the reel crossbars evens the pressure across the length of the reel for smoother operation. It also engages with the feed more smoothly.

The open-center design eliminates obstructions in the reel and provides superior feed movement and unparalleled mixing action. The benefits are unmistakable, with faster, more consistent mixing, improved load leveling, optimized mixer space utilization and fewer dead spots for the ultimate in ration quality.

A mix bar runs diagonally across the center of the reel to help ensure consistent feed movement throughout the entire mixing chamber. The reel crossbars keep feed moving efficiently around the outside of the chamber. The secondary mechanical mixing action from the mix bar provides a fast and thorough mix even in wet, heavy rations with large amounts of distillers grains.

Low Fuel Consumption

Quality performance, with the lowest possible input costs is the goal of every operation. The fast, gentle mixing of KUHN Knight reel mixers helps maximize efficiency and minimize expense. The reel and auger design eliminates much of the force and pressure seen with other mixer types, resulting in low horsepower requirements and, correspondingly, less fuel consumption for economical operation.

Consistent Mixing and Discharge

KUHN Knight reel mixers provide a consistent mix, even with small batches, for a balanced ration from beginning to end. Their quick, even discharge with a more complete cleanout helps save time and maximizes efficiency.

Simple Feeding

With a high discharge point, these mixers allow for the use of a simple slide tray in most feeding situations. The long tray makes it easy to feed deeper into most bunks while preventing feed loss from the wind. This dependable, low-cost option also results in less maintenance.

Designed with You in Mind

Easier Loading

The lowered right side, with a 15” drop, provides a lower side height to provide easier loading, while the two-position axle setting allows versatility to match your unique needs. The upper setting drops the overall height of the machine by 6” for easier loading with skid steers.

Dependable Drive

The roller chains have been sized for increased durability and long service life. The entire heavy-duty chain and sprocket drive run continually in an enclosed oil bath for added protection and longer life. A single-handled latch provides easy access to the oil bath and secure closure to protect the drive system. An improved lip seal keeps oil in, and dirt and debris out to help minimize wear on drive components.

Bolted Auger Flanges

Bolted flanges on the upper and lower augers provide strong connections between the auger tubes and drive shafts for superior durability. They also allow for a single-piece front panel that gives added strength and provides a clean look.

Heavy-Duty Discharge Door

The door discharge and pivot have been redesigned and strengthened for extended service life. The linkage incorporates two ball pivots for smooth operation.

Tailor Your Machine

Multiple Discharge Options

To best suit your feeding needs, you can choose from a slide tray, chain and slat conveyor, or a 3-auger discharge to be equipped on your RA 100 Series mixer.

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.

Chain and Slat Conveyor
Rugged chain and slat conveyor options provide the ultimate in durability and long life. Heavy-duty components ensure reliable service and multiple conveyor length options offer unmatched flexibility to match different feeding situations.

3-Auger Discharge
The 3-auger discharge allows adjustment for feeding into higher bunks. It has a simple, hydraulic drive that provides smooth, even discharge. Long lasting, poly chute liners help prevent rust and limit wear. The 3-auger discharge comes standard with fixed tip-off and built-in magnets.

Trailer, Truck & Stationary Models

To suit your operation’s needs, KUHN Knight RA 100 Series mixers are available in trailer, truck-mounted or stationary configurations.

Trailer models are the most popular configuration as they are the most economical and versatile. Being detachable allows the tractor to be used elsewhere on the farm when not in use for feeding.

Truck-mounted models are a suitable option for those that have to feed cows at several different locations, with large travel distances. This option allows a feeder to quickly get from the mixing location to the feed bunk and back again.

Whether mixing wood chips or a ration for your livestock, KUHN Knight RA 100 Series stationary mixers are ideal for maximizing feeding efficiency and mixer throughput on any operation. Stationary mixers are perfect for producers with centralized feed storage and multiple mixers running throughout the day. By incorporating centralized mixing, one loader operator is often able to keep multiple mixers constantly running, greatly increasing mixing capacity and reducing labor. Also, with the addition of delivery boxes, the mixers do not experience the downtime from driving location to location, and in turn do not receive the additional stress which can be seen from constant travel.

Equipment

Additional Equipment for the RA 100 Series TMR Mixers

Hay Maxx^® System

The Hay Maxx^® System provides enhanced processing of a wide variety of materials. Hay and other bulky materials can be placed on the pan allowing them to be preprocessed by the upper auger before entering the mixing chamber. Additional aggressive, hardened-edge knives are added to the upper auger that help process the hay to the proper length before entering the mixing chamber.

Roughage Maxx^® System

The optional Roughage Maxx^® System incorporates scalloped knives on the lower auger to maximize hay processing. The knives provide a more consistent particle length and more even blending. The result is a more uniform and palatable ration with reduced sorting for improved feed efficiency.

Partial or Full Stainless Steel Liner

The partial liner (shown in silver) covers the most critical wear areas in the mixer and provides added protection and longer life. The full liner completely covers all of the high wear areas, from front to back, for unmatched dependability and long service life. Both provide added protection when mixing more abrasive or corrosive materials, resulting in longer life of the unit shell.

Scale Systems

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

Customer Spotlight: RA 136 & 142

Nick Knepper Hopkinton, Iowa
"When I start cattle on higher roughage rations, it (KUHN Knight RA 136 Helix Reel Auggie) does a better job of mixing. The first feed out of the mixer when I start unloading is the same as the last feed out and that is something I like."
