We couldn't find anything to feed the drafts out of that would hold up to the pushing , rubbing, bumping and normal horse play without busting up or rusting out. We experimented several years on the farm and came up with something that would stand up to normal heavy livestock that won't hurt your show animals. Finally a feed bunk that will outlast your horse ! No sharp edges, no injury. Great for show horses or cattle. Go green with these indestructible livestock feeders, using repurposed tires to feed grain and hay at the same time. We have had these in use everyday for 10+ years and they still look like its their first day on the job.
