GARFIELD PANEL COMPANY ROUND BALE FEEDERS are constructed out of tough 1 ½” 11 gauge tubing. Our round bale feeders come in three sections and use only three long pins for easy set up and break down. This helps avoid losing pins while flipping them. You can also pull one pin, swing open a section and back a round bale into the feeder to avoid always flipping the round bale feeders.
