I've been working on a remote control gate for a few years, and finally think I've got it perfected. Boy it saves time, and cows never escape while going into pens to feed. I know that with a lot of grazing that pen feeding doesn't happen much, but when it does this gate is slick. And quite cheap to make, just hung gate on a panel, and mounted the opener and return spring system on that. If I knew how to download a few pics, I'd do that, but I don't. I've made a few for my neighbors, there pretty tickled seeing as there in there 70's and now they don't force the wife to stand by that dreaded gate. LOL
