Benefit: The feed that the cattle, horses, etc. eat from the suspended area that doesn’t get eaten falls in the spill trays. This prevents the hay falling on the ground and being trampled into the ground.
The Tray Hay Feeder Single has 2 spill trays and the Tray Hay Feeder Double has 4. There is a small gap between the Tray End Sheet and Spill Tray to allow any moisture to exit while not being large enough for feed to fall out freely.
