摘要:
A two-way semi-mounted plow comprises a pull tube having a rear steerable tail wheel and which journals a diagonal beam mounting two rows of opposed left and right-hand plow bottoms. Power means is provided for rotating the beam 180* to alternately engage each row of bottoms with the ground. Each bottom is mounted on the end of a support arm which is pivoted to the beam. A hydraulic ram interconnects each pair of opposed support arms to extend the bottoms until the other ends of the support arms abut the beam. Upon encountering an obstacle, a bottom will deflect, compressing the ram which reacts through the opposed support arm on the frame. Thus only one ram is required for each pair of opposed bottoms.

A semimounted turnover plow having a tail wheel supported on the trailing end of the plow frame in such a manner that the wheel is automatically tilted to an inclined position to counteract side forces acting on the plow bottoms in the plowing position of the plows, and returns to a vertical position when the plows are in a transport position. The wheel is tilted about an inclined axis such that it also changes direction relative to the plow frame as it is tilted.
摘要:
A semimounted, two-way turnover plow including a frame connected at its forward end with a tractor hitch, and having a steerable wheel supporting its trailing end. A remotely operable hydraulic ram at the forward end of the frame controls the position of the wheel with respect to the frame through a control shaft to positively steer the trailing end. The wheel also responds to changes in direction of the tractor to steer the trailing end of the frame in accordance with such changes.
