Abstract
A forwardly folding tillage implement carries a number of ground engaging tools on a tool gang frame disposed to the rear of a carrier frame. A rockshaft is disposed between the carrier frame and the tool gang frame and is movable between four rotated positions about two axes of rotation. A control mechanism controls the relative angular position of the rockshaft. A support mechanism is disposed rearwardly of the axes of rotation to support the rear of the tool gang frame above the ground in the field working position. An abutment member restrains the relative rotation between the rockshaft and the tool gang frame to fully support the tool gang frame on the rockshaft upon rotation of the rockshaft.
Claims15
A forward folding tillage implement comprising:
- a hitch member adapted at a forward end for connection to a prime mover;
- left and right wing members pivotally connected to said hitch member, each said wing member being pivotally movable about a generally vertical pivot axis carried by said hitch member between a transversely extending operating position and a longitudinally extending transport position, said hitch member including a latch mechanism cooperable with said inner wing sections to retain said wing members in said transport position;
- each said wing member including an inner wing section pivotally connected to the corresponding said pivot axis and an outer wing section pivotally connected to said corresponding inner wing section for movement relative thereto about an oscillation axis, said oscillation axis extending generally longitudinally when said wing members are in said operating position to permit said outer wing sections to move generally vertically relative to the corresponding said inner wing sections when in said operating position thus allowing said wing members to follow ground undulations, each said oscillation axis being inclined downwardly and forwardly when said wing members are in said operating position;
- and
- ground engaging wheels supporting each said inner and outer wing section, said ground engaging wheels being movable relative to the corresponding wing section to permit a re-orientation relative thereto between said operating and said transport positions.
A forward folding tillage implement comprising:
- a hitch member adapted at a forward end for connection to a prime mover;
- left and right wing members pivotally connected to said hitch member, each said wing member being pivotally movable about a generally vertical pivot axis carried by said hitch member between a transversely extending operating position and a longitudinally extending transport position;
- a hydraulic cylinder interconnects said hitch member and each of said wing members to effect pivotal movement of said wing members between said operating and said transport positions;
- an actuation bracket pivotally supported on one of said wing members for movement between first and second positions, said actuation bracket being connected to one of said hydraulic cylinders to effect movement thereof;
- a latch mechanism for retaining said wing members in said transport position, said latch mechanism being operatively associated with said actuation bracket to effect movement thereof between a latching configuration in which said wing members are retained in said transport position and an unlatching configuration in which said wing members are free to move into said operating position.
A forward folding tillage implement comprising:
- a hitch member adapted at a forward end for connection to a prime mover;
- left and right wing members pivotally connected to said hitch member, each said wing member being pivotally movable about a generally vertical pivot axis carried by said hitch member between a transversely extending operating position and a longitudinally extending transport position;
- and
- each said wing member including an inner wing section pivotally connected to the corresponding said pivot axis and an outer wing section pivotally connected to said corresponding inner wing section for movement relative thereto about an oscillation axis, each said oscillation axis extending generally longitudinally, downwardly and forwardly when said wing members are in said operating position to permit said outer wing sections to move generally vertically relative to the corresponding said inner wing sections when in said operating position thus allowing said wing members to follow ground undulations.
