The Priefert SS-13 is a heavy-duty, completely reversible crowding system designed for permanent cattle operations. It features a 135-degree sweep with a 20-foot working alley, adjustable to four different widths to accommodate various cattle sizes. This system includes sheeted alley panels that are open at the top, allowing easy pour-on application of insecticides without requiring costly catwalks. The two sheeted preg panels provide secure access for palpation and AI work while doubling as sorting gates. An 8-foot sorting gate and blocking gates are integrated into the sweep for efficient cattle management. The adjustable alley frame with chute attachment makes it simple to connect a Priefert Squeeze Chute at the end of the alley. Sheeted adjustable alley gates reinforce the structure while serving as heavy-duty roll gates for blocking cattle movement. Built to handle demanding conditions, the SS-13 features an architectural-grade powder coat finish that resists rust, scratches, and fading, extending the life of your investment. This design reduces labor requirements while delivering the durability needed for working rank cattle.
