Wing back implement

Claim 2

An agricultural implement to be towed by a tractor or the like, comprising: a frame having wing sections connected at a pivot point, said wing sections each being comprised of a plurality of component sections hingedly connected to each other for pivoting movement about axes parallel to the direction of towing of said implement; a towing linkage having rigid portions extending laterally of the longitudinal axis of said implement said longitudinal axis being parallel to said direction of towing; members connected between at least one of said plurality of component sections of said wing sections on opposite sides of said pivot point and said towing linkage, said members extending between said at least one of said component sections intermediate the ends thereof and said towing linkage in a direction substantially parallel to the direction of implement towing and said towing linkage being removable from said members, said wing sections being pivotable rearwardly about said pivot point upon removal of said towing linkage from the outboard ones of said members to bring the most outwardly distant portions of said wing sections into substantially adjacent transportable condition.

Claim 3

An agricultural implement as in claim 1 wherein said wing sections have a substantially rearwardly directed "V" shaped working configuration having its apex substantially at said pivot point.

Claim 4

An agricultural implement as in claim 2 and further comprising ground working tools connected to each of said wing sections, each of said ground working tools being located forwardly of its inwardly adjacent ground working tool.

Claim 5

An agricultural implement as in claim 3 wherein an equal number of ground working tools are located on each of said wing sections.

Claim 6

An agricultural implement as in claim 4 wherein one pair of two members are attached to each of said wing sections, each of said pairs having an inner and outer member.

Claim 7

An agricultural implement as in claim 5 wherein the end of each of said inner members opposed from said wing sections is pivotably connected to said towing linkage.

Claim 8

An agricultural implement as in claim 6 wherein the intermediate portion of each of said outer members is removably connected to said towing linkage.

Claim 9

An agricultural implement as in claim 7 wherein each of said wing sections comprises a plurality of individual component sections, each of said component sections being hingedly connected to adjacent component sections, said ground working tools being mounted on said component sections.

Claim 10

An agricultural implement in claim 8 wherein said foldable reinforcing assemblies are rotatable about brackets located on said towing linkage.

Claim 11

An agricultural implement as in claim 9 and further comprising a gauge wheel connected to the end of each of said outer members opposed from said wing sections.

Claim 12

An agricultural implement as in claim 10 and further comprising depth control wheels connected to each of said component sections.

Claim 13

An agricultural implement as in claim 11 and further comprising transport wheels, connected to each of the rearward and outboard portion of said wing sections and to the rearward and inward portions of said wing sections adjacent said pivot point.

Claim 14

An agricultural implement as in claim 7 wherein said towing linkage comprises respectively opposed foldable reinforcing assemblies, each of said assemblies being connected to one of said outer members.

Claim 15

An agricultural implement to be towed by a tractor or the like and operable to fold about a pivot point comprising: a frame having wing sections joined at said pivot point and extending outwardly and forwardly therefrom in a generally symmetrical configuration, said wing sections being comprised of a plurality of component sections hingedly connected to each for pivoting movement about axes parallel to the direction of towing of said implement; a towing linkage having rigid portions extending laterally of the longitudinal axis of said implement, said longitudinal axis being parallel to said direction of towing; members between said towing linkage and at least one of said plurality of component sections of said wing sections, said members extending from said component section intermediate the ends thereof to said towing linkage in a direction substantially parallel to the direction of towing of said implement; depth control, transport and gauge wheels, and ground working tools connected to said frame, said gauge wheels being mounted on the outwardmost members on the ends opposed to said frame and said depth control wheels being mounted on said wing sections forwardly of said ground working tools and operable to support said wing sections when in transport, said transport wheels being mounted on each of said wing sections rearwardly of said respective ground working tools and operable to provide support for said wing sections when in transport.

Claim 16

An agricultural implement to be towed by a tractor or the like and operable to fold about a pivot point comprising: a frame having wing sections joined at said pivot point and extending outwardly and forwardly therefrom in a generally symmetrical configuration, said wing sections being comprised of a plurality of component sections hingedly connected to each for pivoting movement about axes parallel to the direction of towing of said implement; a towing linkage having rigid portions extending laterally of the longitudinal axis of said implement, said longitudinal axis being parallel to said direction of towing; members between said towing linkage and at least one of said plurality of component sections of said wing sections, said members extending from said component section intermediate the ends thereof to said towing linkage in a direction substantially parallel to the direction of towing of said implement; depth control, transport and gauge wheels, and ground working tools connected to said frame, said gauge wheels being mounted on the outwardmost members on the ends opposed to said frame and said depth control wheels being mounted on said wing sections forwardly of said ground working tools and operable to support said wing sections when in transport, said transport wheels being mounted on each of said wing sections rearwardly of said respective ground working tools and operable to provide support for said wing sections when in transport.
