Zimmerman Cattle Control knows that anyone working in the dairy economy is facing difficult times at present – but doesn’t believe that means we’re helplessly stuck and can’t do anything about the situation. In that spirit, they have gone back to the drawing board and redesigned two of their products to be more affordable, without sacrificing a speck of quality. The process has actually improved the products. “When we redesigned our headlocks, we discovered we could make them simpler to operate, have less moving parts to wear over time, and have more useful features,” says Keith Zimmerman, Vice President of PBZ LLC, which fabricates the equipment. The lowered cost will be an attractive benefit for dairy farmers who need to keep their belts tight in a tough dairy economy, while purchasing a quality product that will last for a longer duration than most


Zimmerman Cattle Headlocks In the competitive eating environment of free stall housing, stocking density is by far the leading contributor to competition along the feed bunk.
