Abstract: A tillage implement includes an implement frame having a first lengthwise frame member, a second lengthwise frame member, and a lateral frame member connected to and extending between the first and second lengthwise frame members. A hitch assembly is rotatably connected to the implement frame. A wheel assembly is connected to the implement frame and moveable between a raised position and a lowered position. A rockshaft is rotatably connected to the implement frame and connected to the wheel assembly. A leveling assembly is connected to the implement frame, the rockshaft, and the hitch assembly. The leveling assembly is configured to adjust the position of the hitch assembly based on movement of the rockshaft. The leveling assembly includes an actuator connected to and aligned with a leveling link.

Abstract: A soil tiling apparatus (1) having a combing or leveling device (4) mounted in front thereof, wherein, when the tool intensity of the combing or leveling device (4) is adjusted, at the same time in the driving direction a change in the distance between the tool supports to each other or to the trailing soil tilling tools (3) is brought about in a simple manner.
Abstract: A coulter adjusting device for use in a reversible plowing machine having a non-reversible mast frame, a bottom frame secured to the non-reversible mast frame in such a manner as to be rotatable or reversible relative to the non-reversible mast frame, a rotatable shaft for rotating or reversing the bottom frame, plural pairs of bottoms fixed to the bottom frame such that each pair of bottoms is secured to upper and lower sides of the bottom frame respectively, and coulters provided in correspondence with each pair of bottoms, at least one of the coulters being secured to the non-reversible mast frame, includes an adjusting mechanism the position of the coulter secured to the non-reversible mast frame by inclining the coulter on a plane perpendicular to a plowing direction by an angle corresponding to the plowing depth, or by moving the coulter in the plowing width direction by an amount corresponding to the tread of a tractor interlockingly with a reversing operation of the bottom frame.
Abstract: A plow having a main frame beam disposed in a diagonal direction with respect to the direction of travel and having a plurality of plow bottoms equally spaced along the diagonal beam, each bottom being vertically pivotally supported on the beam. A furrow wheel frame is carried on the rear of the beam to swing about a vertical axis. The plow bottoms and wheel frame are connected together and are power operated so that the plows may have their effective plowing width adjusted while at the same time positioning the furrow wheel frame. A hitch connection is carried on the forward end of the plow and is composed of a first part which is adapted for connection to a tractor and a second part which is rearward of the first part and adapted to shift with the plow frame. The two parts are connected by a vertical pivot to permit relative lateral swinging between the parts.
