The S0191 is the S01 chute with a Model 91 Headgate. Priefert’s most popular headgate, the HG91 operates in manual or automatic mode. This upgrade makes it easier for a single operator to run the chute, helping to take some of the 'work' out of working cattle. The S0191 operates using Priefert's patented Infinite Locks. Each feature of this chute is designed to help reduce the danger involved in restraining cattle and to increase the ease and efficiency of use for the operator. Comes standard with HG91 Manual & includes Head Chain.
