Abstract
Abstract An agricultural implement, such as a field cultivator comprising at least two frame sections pivotally connected together in a side-by-side relationship. One frame section may be pivoted relative to the other frame section between a working position substantially in horizontal alignment with the other frame section and a transport position obliquely over the other frame section. Power means is provided for connecting the frame sections; the power means includes means for moving one of the frame sections from the working position to the transport position, and means for moving a frame section from the transport position to the working position.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
191 words
A cultivator comprising: A. at least two frame sections; B. pivot means connecting said frame sections together in sideby-side relationship for movement of a first frame section relative to a second frame section between a working position substantially in horizontal alignment with said second frame section and a transport position obliquely over said second frame section; and C. power means connected to said first frame section including a reciprocating power source and a multibar linkage, said power means: 1. effecting raising said first frame section from said working position to an interim position upon movement of said power source in a first direction, 2. effecting movement of said first frame section from said interim position to said transport position upon movement of said power source in a second direction opposite to said first direction, 3. effecting movement of said first frame section from said transport position to said interim position upon the next movement of said power source in said first direction, and 4. effecting movement of said first frame section from said interim position to said working position upon the next movement of said power source in said second direction.
Claim 2
Dependent Claim
191 words
A cultivator comprising: A. at least two frame sections; B. pivot means connecting said frame sections together in sideby-side relationship for movement of a first frame section relative to a second frame section between a working position substantially in horizontal alignment with said second frame section and a transport position obliquely over said second frame section; and C. power means connected to said first frame section including a reciprocating power source and a multibar linkage, said power means: 1. effecting raising said first frame section from said working position to an interim position upon movement of said power source in a first direction, 2. effecting movement of said first frame section from said interim position to said transport position upon movement of said power source in a second direction opposite to said first direction, 3. effecting movement of said first frame section from said transport position to said interim position upon the next movement of said power source in said first direction, and 4. effecting movement of said first frame section from said interim position to said working position upon the next movement of said power source in said second direction.
Claim 3
Dependent Claim
78 words
