Abstract
A forwardly folding agricultural implement frame includes a tongue having a forward section and a rearward section telescopically extendable relative to the forward section. A carriage having support wheels is mounted on the forward tongue section. Left and right wings are pivotally connected to the rearward tongue section and foldable between a field position wherein the wings are generally perpendicular to the tongue and a transport position wherein the wings are generally parallel to the tongue. During the folding process, the carriage remains generally centered under the frame such that the majority of the weight of the implement is carried by the wheels and not shifted forwardly to the tractor drawbar.
Claims37
A folding agricultural implement frame comprising:
- a) a tongue having a forward tongue section and a rearward tongue section telescopically extendable relative to said forward section;
- b) a wheel carriage mounted on said forward tongue section and supporting said frame above the ground;
- and
- c) left and right wings pivotally connected to said rearward tongue section and movable between an outwardly extending field position and a forwardly extending transport position.
A folding agricultural implement frame comprising:
- a) a tongue having a forward tongue section and a rearward tongue section telescopically movable relative to said forward section between a retracted position and a rearwardly extended position;
- b) a wheel carriage mounted on said forward tongue section and supporting said frame above the ground;
- c) left and right wings pivotally connected to said rearward tongue section;
- and
- d) left and right wing links connecting said left and right wings respectively to said forward tongue section;
- wherein
- e) as said rearward tongue section extends relative to said forward tongue section said left and right wings move from an outwardly extending field position toward a forwardly extending transport position.
A folding agricultural implement frame comprising:
- a) a tongue having a forward tongue section and a rearward tongue section telescopically movable relative to said forward section between a retracted position and a rearwardly extended position;
- b) a clevis having a pair of side plates positioned on opposite sides of said forward tongue section and fixedly connected thereto;
- c) a wheel carriage having a leg pivotally connected between said side plates of said clevis, said wheel carriage supporting said frame above the ground;
- d) left and right wings pivotally connected to said rearward tongue section;
- e) left and right wing links connecting said left and right wings respectively to said forward tongue section;
- and
- f) a hitch having a rearward end pivotally connected between said side plates of said clevis;
- wherein
- g) as said rearward tongue section extends relative to said forward tongue section said left and right wings move from an outwardly extending field position toward a forwardly extending transport position.
The frame as in claim 38 wherein each said first wing latch member includes an upwardly extending barb which is engageable with a respective downwardly extending barb on said respective second wing latch member.
