Tarter’s CattleMaster Series 6 Automatic Headgate is safe and simple enough for one person to operate. It’s ideal for medium or large herds and cattle up to 1,400 lbs. It’s made of heavy-duty 2” tubular steel. It’s preset for auto catch so that there’s no need to be stationed at the controls. The automatic headgate easily adjusts from calves to bulls. The adjustable doors accommodates animals of various sizes. Reversible controls allow you to operate it from either side and positive latching with a rotating door. The overhead bar prevents accidental release of the automatic headgate.
