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 individual pumps.
