Double Duty Twin Chain ®
Four Section Swath Width Control
The Double Duty Twin Chain offers four section swath width
automatic adjustability, spreading multiple widths and varying
Unique control systems, patented funnel control, and patented
system is perfect for spreading around waterways, point rows, and
control and the industry’s widest, most accurate spread pattern.
reverse rotating spinners combine to make the Double Duty spreaders the most trusted in the industry.
The Double Duty and Double Duty Twin Chain spreaders
produce a repeatable, predictable, and consistent pattern, every time. The Double Duty spreads a guaranteed 90-120-foot pattern
without time consuming spinner, funnel, or chute adjustments between materials or rates. The Double Duty’s unique funnel
design carefully directs material flow ensuring a consistent and accurate spread pattern.
The new Double Duty Twin Chain provides users with quick,

boundaries, consistent with the 4R nutrient stewardship program. The Double Duty’s swath width control system utilizes twin bar
chains with individual shutoffs and a pneumatically controlled, adjustable-vane funnel to direct product. The precise placement
of product onto the spinner discs control the width and direction of the spread pattern. When combined with individual chain shut-off, up to four individual spread sections are possible.
The Double Duty Twin Chain allows you to cover more acres annually, with less compaction, less fuel, and fewer stops than any
other applicator to ultimately increase your productivity and your return-on-investment.
