We have a WW chute with OB gate in the back. But we took the head gate off that came on it, and it has a preifert on there now. The chute is old, but it works good. Lil WD40 on the hinges before working ever time and it does a good job. The only complaint I have is that gap that was mentioned before. in the front, where their front hooves can get stuck. I don't know what we'll do, but that WILL be fixed before the next cow workin. Just the other day, when we trimmed heifer heads one got her foot caught in there, and she limped around for a couple days. That's somethin that can be avoided with a short amount of work to fix that. From different chutes we've looked at over the years, they all have gaps and spaces cows can get hung up in. Looks like the companies would see that and remedy it before it goes on the market.
