No other product invented by the Priefert family has had more of an impact on the cattle industry than the full front-opening headgate invented by Marvin Priefert in1964. The Model 91 Headgate is based on Marvin’s original design and is by far Priefert’s most popular headgate to date. If you are in the market for a good headgate that will not only stand the test of time, but also increase your productivity and efficiency, then this is the headgate for you. The HG91 provides safety for both animal and operator, helping to take some of the “work” out of working cattle. Priefert’s Model 91 headgate operates in manual or automatic mode and its Infinite Locking System is guaranteed for life.
