This simple and efficient design does not include a sweep, but uses a holding pen and funnel to direct livestock into a 12’ working alley that also includes a Model 91 Headgate with Headgate Stand. The OS-7 is a durable and affordable crowding system that helps reduce the labor needed for working cattle. This system is constructed with Premier Panels, our number one selling cattle panel, and the HG91 headgate, which works in manual or automatic mode. The “no-back” Alley Stop can be easily adjusted to prevent cattle from backing out of the alley. This system is ideal for small operations, but can be easily expanded upon to accommodate larger herd sizes.
