Claims
- 1. A forward-folding farm implement comprising:
a carrier frame including two wing sections for carrying working tools on opposing sides of an implement center line, said wing sections being oriented perpendicularly to the direction of travel when in a field operationg position, each of said wing sections being supported for pivotal movement about a vertical folding axis for movement of said wing sections between said field operating position and a transport position in which said wing sections are oriented generally parallel to the direction of travel, such that said implement has a narrower width in said transport position than in said field operation position; a primary hitch member located forwardly of said wing sections when in said field operating position and being adapted to connect said carrier frame to a prime mover; and a secondary hitch mechanism adapted to connect a second implement at a hitch point rearwardly of said carrier frame and including two secondary hitch members located, respectively, on opposing sides of said implement center line, said secondary hitch members being pivotally connected to corresponding said wing sections such the movement of said wing sections from said field operating position to said transport position is operable to move said hitch point closer to said vertical folding axis.
- 2. The farm implement of claim 1, wherein said secondary hitch members are connected to said wing sections at connection points spaced laterally of said vertical folding axis.
- 3. The farm implement of claim 2, wherein said primary hitch member is telescopic, extending in length as said wing sections move from said field operating position to said transport position, said secondary hitch members being connected to said telescopic primary hitch member to be movable therewith.
- 4. The farm implement of claim 3, wherein each said secondary hitch member is connected to said corresponding wing section by a support arm pivotally interconnecting said secondary hitch members and said wing sections.
- 5. The farm implement of claim 4, wherein said support arms stabilize said secondary hitch members along said implement center line.
- 6. In a farm implement having a carrier frame including two wing sections for carrying working tools on opposing sides of an implement center line, said wing sections being oriented perpendicularly to the direction of travel when in a field operationg position, each of said wing sections being supported for pivotal movement about a vertical folding axis for movement of said wing sections between said field operating position and a transport position in which said wing sections are oriented generally parallel to the direction of travel, such that said implement has a narrower width in said transport position than in said field operation position; and a primary hitch member located forwardly of said wing sections when in said field operating position and being adapted to connect said carrier frame to a prime mover; the improvement comprising:
a secondary hitch mechanism adapted to connect a second implement at a hitch point rearwardly of said carrier frame and including two secondary hitch members located, respectively, on opposing sides of said implement center line, said secondary hitch members being pivotally connected to corresponding said wing sections such the movement of said wing sections from said field operating position to said transport position is operable to move said hitch point closer to said vertical folding axis.
- 7. The farm implement of claim 6, wherein said primary hitch member is telescopic, extending in length as said wing sections move from said field operating position to said transport position, said secondary hitch members being connected to said telescopic primary hitch member to be movable therewith.
- 8. The farm implement of claim 7, wherein said secondary hitch members are connected to said wing sections at connection points spaced laterally of said vertical folding axis.
- 9. The farm implement of claim 8, wherein each said secondary hitch member is connected to said corresponding wing section by a support arm pivotally interconnecting said secondary hitch members and said wing sections.
- 10. A forward-folding farm implement comprising:
a carrier frame including two wing sections for carrying working tools on opposing sides of an implement center line, said wing sections being oriented perpendicularly to the direction of travel when in a field operationg position, each of said wing sections being supported for pivotal movement about a vertical folding axis for movement of said wing sections between said field operating position and a transport position in which said wing sections are oriented generally parallel to the direction of travel, such that said implement has a narrower width in said transport position than in said field operation position; a telescopic primary hitch member located forwardly of said wing sections when in said field operating position and being adapted to connect said carrier frame to a prime mover; said primary hitch member extending in length as said wing sections move from said field operating position to said transport position; and a secondary hitch mechanism connected to said telescopic primary hitch member to be movable therewith and being adapted to connect a second implement at a hitch point rearwardly of said carrier frame, said secondary hitch mechanism including two secondary hitch members located, respectively, on opposing sides of said implement center line, said secondary hitch members being pivotally connected to corresponding said wing sections such the movement of said wing sections from said field operating position to said transport position is operable to move said hitch point closer to said vertical folding axis.
- 11. The farm implement of claim 10, wherein said secondary hitch members are connected to said wing sections at connection points spaced laterally of said vertical folding axis, and wherein each said secondary hitch member is connected to said corresponding wing section by a support arm pivotally interconnecting said secondary hitch members and said wing sections.
- 12. The farm implement of claim 11, wherein said support arms stabilize said secondary hitch members along said implement center line.
