The KUHN Knight PS 270 ProSpread® apron box manure spreader is a high-capacity, non-commercial spreader designed for feeder, cow/calf, and dairy operations that process a wide array of semi-solid and solid materials. This machine pairs superior look and build with performance and is backed by rigorous testing and user feedback. A 10-degree sidewall flare provides greater capacity while still maintaining ease of loading and unit maneuverability. A heavy-duty guillotine gate delivers greater metering capability and material flow management. Choose between VertiSpread® vertical beaters and the AccuSpread® spinner module to best fit the needs of your operation. Improved beater location provides an enhanced spreading pattern by streamlining material flow from the apron to the beaters. Additionally, an optional scale system is available for precise monitoring and application tracking. This spreader has a heaped capacity of 690 ft³.

Your benefits

Built To Last


All-Steel, Welded Construction

An all-steel construction provides the backbone and solid framework for these spreaders. This simple, yet effective design keeps the sides and beater panels aligned for the life of the machine. The all-welded construction includes a reinforced tongue that pulls directly from the axle for added strength and durability. An A-frame assembly keeps the sides and beater panels correctly aligned for strong box integrity. A round-tube bottom, on the rear, promotes self-cleaning by helping prevent material breakup.

Sidewall Flare

The sidewall flare provides greater heaping capacity without increasing the overall size of the machine. This makes the unit easier to load with the wider flotation tires. This design also allows the sidewalls to be supported by fewer, yet stronger exterior uprights. The box is constructed with 10-gauge steel to ensure a strong box sidewall.

Center-Mounted Driveline

This simple design eliminates the need for extra chains and sprockets that are necessary for a side-mounted driveline. This simple design uses high-quality sealed bearings to provide reliable power delivery with lower maintenance requirements. The driveline is located underneath the unit, thus reducing the possibility of damage during loading.

Dual-Apron Design

To ensure quality and dependability the PS 270 is equipped with a dual apron which helps to distribute the load more evenly. The 667 XH pintle apron chain provides increased strength with ease of maintenance and is accompanied by heavy-duty, self-cleaning sprockets welded to a 2” steel shaft. The dual apron features offset 1 ½” x 2” steel slats which provide more consistent feeding of material. The dual apron also offers increased rigidity and longevity for both apron chains and slats. A hydraulic-driven, direct-drive gearbox provides reliable power with low maintenance.

High-Density, Two-Piece Poly Floor

A two-piece, ⅝” solid poly floor provides more strength and durability than individual tongue and groove boards while reducing friction. This means that less power is required for unloading versus alternative steel or wooden floors. The poly floor provides impact resistance when dropping heavy loads into the spreader. The two-piece design allows for expansion or contraction with changing temperatures. The plastic floor also reduces winter freeze-down issues to provide trouble-free service and long life.

Superior Spreading & Material Control


Choice of Beater Modules & Improved Location

All PS 270 spreaders come with the choice of a VertiSpread vertical beater module or AccuSpread spinner module allowing you to customize your machine to your operation. To give you even greater machine versatility, beater modules can easily be removed for safe storage while stockpiling manure or when switching modules.

An improved beater location on PS 270 models provides an enhanced spreading pattern by streamlining material flow from the apron to the beaters.

VertiSpread® Vertical Beaters

VertiSpread® vertical beaters provide quality spreading performance for a wider variety of dry materials, from tough materials like pen pack, to finer materials like dry dirt compost. They can provide the same fast unloading and high application rates as horizontal beaters, but with a wider spread pattern and more consistent material breakup.

Heavy-duty vertical beaters, equipped with 5/8” flighting and hardened steel beater tips, provide a durable beater capable of handling almost anything. The beater flighting overlaps ensuring an optimal spread pattern. All beaters are equipped with adjustable, two-position, bolt-on teeth which makes maintenance and replacement easy. All teeth are through-hardened to ensure strength and durability. Power to the beaters is routed through a fully enclosed, integral gearbox, providing a strong and reliable power supply with low maintenance requirements.

AccuSpread® Spinner Module

The new Gen II AccuSpread® spinner discharge provides the widest, most uniform spread pattern available, and coupled with the use of the metering gate, is able to accurately spread nutrient-dense materials at low rates. The helical-style beater flighting provides excellent material breakup, even in tough materials such as pen pack. A free-floating lower deflector ensures that the material is placed on the spinner discs correctly, but also allows for movement in case of an obstruction or surge in material.

Heavy-Duty Guillotine Gate

A heavy-duty guillotine gate provides increased material metering capability. This design reduces the possibility of material flow issues, such as lodging or bridging, by eliminating guide rails protruding inside of the box, as well as increasing opening height. Each guillotine endgate comes standard with a gate position indicator for operator convenience.

Reduced Soil Compaction


Heavy-Duty Tandem Axle

A rugged, tandem axle provides greater flotation and reduced soil compaction. A tandem axle allows the unit to travel across a wide range of terrain with ease. Bogie systems utilize a simpler design with fewer moving parts which reduces maintenance requirements and increases dependability.

High-Flotation Tires & Hydraulic Disc Brakes

To ensure minimal soil compaction, all PS 270 units are equipped with high-flotation tires. Two wheel hydraulic disc brakes are available providing added safety, both on the road and in the field. Brakes can be removed from the unit.
