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.
Claims36
A folding agricultural implement frame comprising:
- a) an extendable tongue having a forward tongue section and a rearward tongue section telescopically connected to said forward tongue section, said rearward tongue section moveable relative to said forward tongue section to vary a length of said tongue between a retracted length and a longer extended length;
- b) a hitch connected to said forward tongue section, said hitch securable to a towing vehicle;
- c) a wheel carriage mounted on said forward tongue section and supporting said frame above the ground;
- said wheel carriage connected to said forward tongue section such that the longitudinal position of said wheel carriage is fixed relative to said hitch;
- and
- d) 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) an extendable tongue having a forward tongue section and a rearward tongue section telescopically connected to said forward tongue section, said rearward tongue section movable relative to said forward tongue section to vary a length of said tongue between a retracted length and a longer extended length;
- b) a hitch connected to said forward tongue section, said hitch securable to a towing vehicle;
- c) a wheel carriage mounted on said forward tongue section and supporting said frame above the ground;
- said wheel carriage connected to said forward tongue section such that the longitudinal position of said wheel carriage is fixed relative to said hitch;
- and
- d) left and right wings pivotally connected to said rearward tongue section;
- and
- e) left and right wing links connecting said left and right wings respectively to said forward tongue section;
- wherein
- f) 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) an extendable tongue having a forward tongue section and a rearward tongue section telescopically connected to said forward tongue section, said rearward tongue section movable relative to said forward tongue section to vary a length of said tongue between a retracted length and a longer extended length;
- b) a clevis having a pair of side plates positioned on opposite sides of said forward tongue section and fixedly connected thereto;
- c) a hitch having a rearward end pivotally connected between said side plates of said clevis;
- d) a wheel carriage having a leg pivotally connected between said side plates of said clevis and such that the longitudinal position of said wheel carriage is fixed relative to said hitch, said wheel carriage supporting said frame above the ground;
- e) left and right wings pivotally connected to said rearward tongue section;
- and
- f) left and right wing links connecting said left and right wings respectively to said forward tongue section;
- 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.
