Features
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 250, 260, 270 & 280 spreaders are 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 (optional on PS 250, standard on PS 260/270/280) . 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
Superior Spreading & Material Control
Choice of Beater Modules & Improved Location
PS 250 & 260 spreaders come with the choice of horizontal beaters, VertiSpread vertical beaters or an AccuSpread spinner module allowing you to customize your machine to your operation. The PS 270 & 280 are available with VertiSpread vertical beaters or the AccuSpread spinner discharge. 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 the PS 250, 260, 270 & 280 provides an enhanced spreading pattern by streamlining material flow from the apron to the beaters.
Horizontal Beaters
A traditional design that provides good material breakup at an affordable price. Standard with two, 20" (50.8 cm) beaters. An optional lower beater is also available for increased material breakup. Not available on PS 270 or 280.
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.
PS 250/260 models come standard with 3/8" (1 cm) thick steel beater flighting with standard or hardened beater teeth. PS 270 and 280 models feature heavy-duty vertical beaters, equipped with 5/8” (1.6 cm) flighting and hardened steel beater tips, providing 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. PS 250 & PS 260 models can be upgraded to the heavy-duty vertical beaters.
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 & Tire Options
A rugged, tandem axle allows the unit to travel across a wide range of terrain with ease. 8- or 10-bolt bogie systems utilize a simpler design with fewer moving parts which reduces maintenance requirements and increases dependability. Brakes and/or scales require a bolted spindle. If neither option is wanted a welded spindle will be used. 10-Bolt bogies are best suited in heavy material applications.
Multiple tire arrangements are available ranging from truck, to implements, to high-flotation tires. Truck tires are durable for extended road travel, but provide limited flotation in the field. Implement tires provide good in-field flotation but have less durability during extended road travel. The high-flotation, low-profile tires provide good durability and flotation but have a higher price point versus the two other tire options. PS 270 & 280 models only come with high-flotation tires.
Hydraulic Disc Brakes
Hydraulic disc brakes are more reliable in manure applications than drum or air brakes since they are easier to keep free of foreign material. The optional hydraulic brakes are activated using the hydraulic braking port provided on the tractor. PS 270 & 280 models come standard with hydraulic disc brakes, but can be ordered without.
