Abstract
A reversible plow comprising a three point hitch, a pivotally mounted tool bar provided with a plurality of adjustable plow gangs, and gauge wheels wherein said tool bar can be shifted from left of center to right of center, and back, by a hydraulic piston such that the plowed ground can be directed in a desired direction.
Claims27
A reversible plow comprising:
- (a) a frame having a longitudinal axis;
- (b) hitch means secured to the front portion of said frame and by which said frame can be attached and detached to the hitches of a tractor so that when said frame is attached to said tractor, said frame may be raised and lowered and towed in a longitudinal direction by said tractor;
- (c) pivot means carried by said frame, said pivot means being disposed along an upright axis;
- (d) a tool bar connected at its intermediate portion to said pivot means, a front portion of said tool bar protruding in a forwardly direction from said pivot means, a rear portion of said tool bar extending rearwardly from said pivot means, said tool bar being pivotable about said pivot means;
- (e) a plurality of moldboard supports removably secured at spaced intervals to said tool bar, said moldboard supports having downwardly extending shanks;
- (f) moldboards removably secured to said shanks;
- (g) a guide bar fixed within said frame, said guide bar being concaved about said pivot means, the forward end portion of said tool bar terminating adjacent to said guide bar;
- and
- (h) means protruding forwardly from the end portion of said tool bar for engaging the upper and lower surfaces of said guide bar, said means engaging said guide bar including a pair of wear plates protruding forwardly from said end portion of said tool bar for engaging upper and lower surfaces of said guide bar, said wear plates being flat plastic members which are removable from said means at the end portion of said tool bar.
A reversible plow of the type having an elongated frame, a tool bar pivotally secured to said frame for swinging about a vertical axes, support means for supporting a bidirectional moldboard suspended from said tool bar wherein said bidirectional moldboard is arcuate about a horizontal axis, and an arcuate moldboard wear plate conforming in shape and removably secured to a front earth engaging surface of said moldboard, said moldboard plate being reversible so that it is selectively received on said moldboard in either of two positions.
A plow of the type having a frame, a tool bar pivotally supported by its intermediate portion on said frame for swinging about a vertical axis, and a plurality of bidirectional moldboards supported by said tool bar in spaced relationship along said toolbar, the improvement comprising a pair of forward wheels protruding from the forward corner portions of said frame for engaging the ground and for providing substantial support for the forward portion of said frame, said forward wheels being adjustable with respect to said frame for varying the height of said frame to vary the depth of penetration of said moldboards into the ground, a rear wheel protruding from the rear end portion of said tool bar for engaging the ground rearwardly of said front wheels and support means for said rear wheel, said support means being pivotable for varying the height of said rear wheel with respect to said frame and means for disposing said rear wheel for travel along the ground in a path parallel to the path of said front wheels.
A reversible plow of the type having a frame, a tool bar pivotally mounted to said frame for swinging from one position to another about a vertical axis of said frame, said tool bar having a portion thereof protruding rearwardly of said frame, a boom mounted on said rearwardly protruding portion of said tool bar and protruding rearwardly therefrom, a wheel pivotally mounted on said boom, means for pivotally mounting said boom to said tool bar and means for incrementally adjusting the pivotal position of said boom with respect to said tool bar.
A reversible plow of the type comprising:
- (a) a main frame for being moved in a longitudinal direction along a path of travel;
- (b) a tool bar pivotally carried by said frame for being pivoted to a first angular position with respect to said direction of travel so that the tool bar extends forwardly and toward one side of said frame and pivoted to a second angular position with respect to said direction of travel so that the tool bar extends forwardly and toward the other side of said frame;
- (c) a plurality of bidirectional unconnected moldboards disposed in spaced relationship to each other along the length of said tool bar, so as to throw dirt to one side of the direction of travel when the tool bar is in its first angular position and to thor dirt to the other side of the direction of travel when the tool bar is in its second angular position;
- (d) an arcuate guide bar carried by said main frame, the forward end of said tool bar passing adjacent to the rear surface of said guide bar in the swing of said tool bar from one of its positions to the other;
- (e) a plurality of clamp means removeably clamped at spaced locations along said tool bar for respectively supporting said moldboards in their spaced relationship along said tool bar;
- and
- (f) wear plates carried by and protruding from the forward end of the forwardmost clamp mean for sandwiching said guide bar between said wear plates.
A reversible plow of the type having a frame, a tool bar pivotally mounted to said frame for swinging from one position to another about a vertical axis of said frame, said tool bar having a portion thereof protruding rearwardly of said frame, a boom pivotally mounted by its forward end portion to an intermediate portion of said rearwardly extending portion of said tool bar, said boom being pivotally carried on top of said tool bar for rotation by its forward portion about a horizontal axis, said boom protruding rearwardly beyond the rear end of said tool bar, said boom being moveable upwardly and downwardly, a wheel pivotally mounted on the rear portion of said boom, and stop means spaced sufficiently above said tool bar and adjustable toward and away from said tool bar for permitting limited upward and downward movement of said boom until it is arrested by said stop means or by said tool bar, respectively.
A plow of the type having a frame, a tool bar pivotally supported by its intermediate portion on said frame for swinging about a vertical axis, and a plurality of bidirectional moldboards supported by said tool bar in spaced relationship along said toolbar, the improvement comprising a pair of forward wheels disposed adjacent to the forward corner portions of said frame for engaging the ground and traveling along parallel paths of travel when the plow is towed, said wheels providing substantial support for the forward portion of said frame, the positions of said forward wheels being adjustable with respect to said frame for varying the height of said frame to vary the depth of penetration of said moldboards into the ground, a rear wheel disposed adjacent to the rear end portion of said tool bar for engaging the ground rearwardly of said front wheels, support means on said rear portion of said tool bar for supporting said rear wheel, said support means being pivotable for varying the height of said rear wheel with respect to said frame and means for disposing said rear wheel for travel along the ground in a path parallel to the paths of travel of said front wheels.
