Overview
Proven Legacy. Tough Performance.
The KUHN Knight SLC 200 Series carries on the ProTwin Slinger legacy of rugged, reliable performance. With 3,200–5,000‑gallon capacities, these commercial‑size spreaders handle diverse materials across agricultural, municipal and industrial applications.
KUHN Knight SLC 200 Series ProTwin® Slinger® commercial manure spreaders set the standard for fast, efficient spreading—even in the most demanding environments. Designed to handle heavy, sand-laden manure with ease, these spreaders deliver unmatched reliability and performance. The unique twin-auger design and exclusive V-body construction ensure smooth material flow and superior versatility, tackling the widest range of materials compared to any spreader on the market. Complete adjustability of the 18-hammer discharge provides excellent material breakup for consistent, even spreading. With large-capacity truck-mount or trailer models, the SLC 200 Series combines rugged durability, efficiency, and adaptability—giving you maximum return on your investment.
Features
Proven, ProTwin Design
The raised right auger moves material rearward to keep the load evenly distributed. The left, lower auger moves material forward to continuously feed the discharge door
Consistent Flow to the Discharge
The continuously welded V-body tank helps provide a reliable material flow, continuously feeding material down to the augers. Combined with the unique auger design, this helps ensure constant delivery of material to the swinging hammer discharge.
Eliminates Bridging
The well-proven, twin-auger design eliminates material bridging. The two augers work together to create a bidirectional flow that provides constant agitation and steady movement, even with the most challenging materials.

Multi-Purpose Spreader
The continuously welded V-body tank will hold both wet and dry materials. This feature allows the Slinger to handle the widest variety of materials compared to any spreader on the market, including soupy gutter manure, semi-solids, separated solids, compost, bedding pack, mulch products and many more.

Rugged Undercarriage
The heavy-duty undercarriage is built for dependable service under heavy use in the toughest conditions, including hauling sand-laden manure. All SLC models come standard with tandem axles.

Heavy-Duty Hammer Design
The KUHN hammer design features more wear surface on the bottom edge to extend hammer life. The fully adjustable shroud helps decrease wear, extending life even further. Nylon bushings and washers help prevent premature wear to the bolts, hammers and hammer shaft ears.

Wide, 18-Hammer Discharge
The KUHN hammer design features more wear surface on the bottom edge to extend hammer life. The fully adjustable shroud helps decrease wear, extending life even further. Nylon bushings and washers help prevent premature wear to the bolts, hammers and hammer shaft ears.

Adjustable Shroud and Sill
Incremental adjustment allows for optimal setting of the clearance between the door sill and the toes of the hammers. Independent adjustment of the door sill and shroud help maintain the clearance between the hammers and the full internal radius of the shroud. Maintaining proper clearance enhances the performance of the hammers and their ability to carry material.

Adjustable Deflector
The hydraulically adjustable deflector provides the ability to conveniently regulate the spread pattern from the tractor seat while spreading. This allows close control of the spreading width for accurate nutrient placement. The deflector stores in the down position and although it is not watertight, it completely closes off the discharge area to help prevent material loss during transport.

Durable, Heavy-Duty Drive
The SLC 200 Series features a fixed, welded drive enclosure for maximum strength and reliability. The durable, heavy-duty drive requires minimal maintenance and delivers years of dependable service. There are no rear chains or sprockets, and the entire drive is enclosed in a front oil bath that provides constant lubrication to chains, bearings, and sprockets—ensuring smooth operation and long-lasting performance compared to the previous removable cartridge design.

Independent Auger Protection
The drive of the SLC 200 Series manure spreaders incorporates individual shear protection for each auger. The shear bolts are conveniently located in the oil bath enclosure for easy access. They provide effective protection for the chains, sprockets, bearings and shafts against damage due to overload, wedging and obstructions.

Enhanced Auger Durability
Hardened front auger plugs prevent oil bath contamination and reduce wear in heavy sand environments. Replaceable rear auger sleeves allow for quick, cost-effective maintenance without replacing the entire auger assembly—saving time and money.

Overrunning Clutch on Hammer Shaft
The overrunning clutch not the hammer shaft allows it to rotate freely when the PTO is disengaged. This reduces backlash on the PTO and on the spreader drive components for less wear and longer life.

Added Shear Protection
Both augers feature simplified shear bolt protection on the transfer paddles. Transfer paddles on the right auger deliver material to the left auger. Paddles on the left auger deliver material to the discharge. The paddles are also split for easy removal and replacement if necessary.

Equipment
Truck Mount Models
The SLC 232 and 241 are available as a truck mount for applications requiring longer travel distances. Mechanical and hydrostatic drive options are available.

Scale System
A scale system is available for all SLC models, porviding accurate application and tracking of applied nutrients. This system, combined with the latest scale head technology, provides integrated manure application management and record keeping capabilities. Trailer models feature a 5-point system of four weigh bars in the wheel spindles and one in the hitch. Truck models use a 3-point system.

Hydraulic Disc Brakes
Hydraulic disc brakes are optional for SLC 232 and 241 models and standard on SLC 250 trailer models. Brakes provide additional stopping capabilities for faster stopping of the heavy loads hauled by these hgih-capacity machines.

Hydraulic Lid
The lid can be raised and lowered hydraulically and provides secure closure to haul slurry-type materials. While it is not completely water-tight, it does an excellent job helping to contain semi-liquid materials without worry of spills during transport.

Dual-Seal Bearings
Dual-seal bearings are designed to keep liquid in the tank and away from the critical drive components. With these seals, liquid manure and other caustic liquids are less able to penetrate the Nylatron bearings or contaminate the oil bath reservoir.
