ABSTRACT:
A lubricating system for plow blades has a plurality of tube outlets positioned near a bottom portion of a plow blade and aligned to expel a dilute polymer lubricating fluid upward and onto a surface of the plow blade. As the plow blade scrapes up ground material, the scrapings distribute the lubricating fluid over the surface of the plow blade. Each of the tube outlets is supplied with lubricating fluid from a storage container via a pump connected to a positive displacement distribution block. In a farm plow system having eight separate plowshares, four positive displacement distribution blocks and one master distribution block are employed to supply lubricating fluid to twenty tube outlets.
