The First of Its Kind, ProTwin® Design

ProTwin® Design

The raised, right auger moves material rearward to keep the load level. The left, lower auger moves material forward to continuously feed the discharge door.

  • Consistent Flow to the Discharge: The steep, slanted sides help 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. From soupy manure, to semi-solids, separated solids, compost, bedding pack, mulch and many other materials, the ProTwin® Slinger® can fit the needs of your operation.


Fast Unloading with Consistent Spread Pattern

Enhanced Hammer Design

A new hammer design features more wear surface on the bottom edge to extend hammer life. The new 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, 15-Hammer Discharge

The SL 114, 118 and 124 models feature a wide, 15-hammer discharge for fast, efficient unloading of all material types. The discharge on the SL 114 offers a 25% increase in unloading capacity compared to the previous model. The wide, aggressive hammers effectively shear material and provide a consistent, even spread pattern. The SL 110 features a 12-hammer discharge.

Adjustable Shroud

Adjustable shroud design provides full adjustment for optimal setting of the clearance between the shroud and the hammers. Maintaining a proper clearance enhances the shearing performance of the hammers to provide a more consistent material flow and more even spreading.

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 water tight, it completely closes off the discharge area to help prevent material loss during transport.


Rugged Undercarriage

The heavy-duty undercarriage is built for dependable service under heavy use in the toughest conditions, including hauling sand-laden manure. The SL 110 model comes standard with single-axle configuration only. The SL 114 can be equipped with either single or tandem axle. The SL 118 and 124 come standard with tandem axles.

Splash Guards

The SL 110 and 114 feature standard steel splash guards, while the SL 118 and 124 have splash guards with a rugged steel front panel and bump-proof rubber sides. The splash guards help keep liquid and slurry-type materials from spilling during transport and are designed to absorb occasional contact with bucket edges while loading.

Simple Front Drive

The SL 110 and 114 feature a simple, yet dependable front drive. The chest-style front enclosure, on all models, allows for easy maintenance and inspection of any drive components. Gas-charged cylinders hold the lid up and out of the way, while the wide opening allows convenient service.

Fully Enclosed, Front Oil Bath

The SL 118 and 124 feature a fully enclosed, front oil bath. A dependable heavy-duty roller chain drive runs in oil and has spring-loaded, self-aligning poly tighteners for long life. Final drive shafts and sprockets are splined for strength and serviceability.

Upgraded from the previous 8100 Series, the SL 118 and 124 now offer shear protection for the upper and lower auger to help limit damage from foreign materials. The shear assembly is located in the front oil bath for the lower auger and on the rear drive for the upper auger.

Dual-Seal Bearings

Dual-seal bearings, on the SL 118 and 124, 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.
