Pen Trailers

Model: Bar‑M Pen Trailer (6 & 8 Pen Bumper Pull)

The Bar‑M Pen Trailer was designed for livestock producers who need more than just a way to haul animals—they need a trailer that helps them work smarter, stay organized, and keep livestock comfortable on every trip.

Available in both 6‑pen and 8‑pen configurations, the Bar‑M Pen Trailer combines rugged aluminum construction with a highly adaptable interior that allows producers to sort, separate, and transport animals with confidence. The convertible pen system, integrated feeder rails, individual feed windows, and thoughtful ventilation features make daily loading, feeding, and livestock management more efficient.

Built on a durable all-aluminum frame with a seamless one-piece roof and a heavy-duty American-made floor system, this trailer is engineered for years of dependable service. Every detail—from the reinforced pen dividers and full-length side slats to the LED lighting and torsion axle suspension—is designed to withstand the demands of real-world agricultural use while maintaining a smooth ride down the road.

A spacious front tack and storage area keeps feed, equipment, and supplies organized and protected, while available power options, interior lighting, roof vents, and climate-control features help make every trip more productive and convenient. Multiple loading and access configurations provide flexibility for a wide variety of operations, helping reduce stress on both livestock and handlers.

Whether you’re moving animals across the farm, heading to a sale barn, transporting show stock, or managing a busy production schedule, the Bar‑M Pen Trailer delivers the durability, versatility, and livestock-focused design that producers can depend on day after day.
