The Standard HayBoss Feeder is designed to fit any size round bale or up to 16 small square bales. It is made from galvanized steel to ensure maximum durability. The high quality, thick nylon net is self tensioned by the spring loaded roller, always keeping the net taut no matter the amount of feed inside. This also enables the feeder to be put on a fence line to feed two paddocks at once. Please choose #1 Net (approx. 1 ¼” diamonds) or #2 Net (approx. 1 5/8” diamonds) to go with your feeder. This is the #1 Net. Rain, snow, mud, wind and waste are no longer an issue with HayBoss Feeders. For loading, simply unlatch the net handles and allow the net to roll up on the rollers, load bale on end, cut strings or wrap and stretch net around the bale and re-latch the handle.
