Two-way, multiple bottom plow with lift assist

摘要

An improved two-way, multiple bottom plow is described. The plow is provided with an hydraulically actuated lift assist mechanism which works in conjunction with the tractor hitch to lift the plow out of the plowing position. A hydraulic system is provided for automatically pivoting the roll-over portion of the plow from one side of the tractor to the opposite side. Ascension of the roll-over portion of the plow to a point past the vertical is effected by powered hydraulic roll-over cylinder which is then shut off. The roll-over portion of the plow then descends under its own weight against the resistance of trapped pressure fluid which can only bleed off through a restricted orifice. The top hitch between tractor and plow is a spring biased pivotable connection which can "float" relative to the plow.
