This high quality chisel plow is made of solid plate and channel steel. Heavy draw bar is adjustable to various heights. Individual spring mounting of coulters prevents damage when striking rocks and other solid objects. 20" diameter coulter blades cut up stalks and stubble and improve the work done by the 4" twisted shovels. 31" spring cushioned shanks make deep penetration possible. Coulters can be raised above ground when not needed. Dual hydraulic lift system independently sets desired coulter and shank depths. Coulter hubs rotate on tapered roller bearings with triple lip seals. Also, more features and specifications.
