Abstract
A hay raking and windrowing apparatus having a tool bar adapted to be attached to a prime mover and having a side delivery rake attached to one side thereof for raking hay rearwardly and inwardly and a second side delivery rake on the other side of the tool bar for also raking hay rearwardly and inwardly so that both side delivery rakes together produce a single windrow. A folding apparatus is provided on each end of the tool bar for hydraulically folding the rakes between a lowered field operative position and a raised transport position. Hydraulic cylinders are preferably used to move the rakes between the transport and operative positions thereof.
Claims21
A hay raking and windrowing apparatus comprising:
- a tool bar adapted to be attached to a prime mover, said tool bar having a first end, a second end, and a longitudinal axis
- a first side deliver hay rake means for raking hay and moving it into a windrow on the inner rear end thereof;
- first rake attachment means for attaching said first rake means to said first end of said tool bar;
- first folding means for pivotally mounting said first rake attachment means to said tool bar about a first axis between a downward operative position;
- wherein a portion of the rake attachment means is aligned along said longitudinal axis and a raised transport position;
- wherein said portion of the rake attachment means is disposed at an angle to the said longitudinal axis;
- first control mean for selectively moving said first rake attachment means and said first rake means between said downward operative position and said raised transport position;
- a second side delivery hay rake means for raking hay and moving it into a windrow on the inner rear end thereof;
- second rake attachment means for attaching said second rake means to one end of said tool bar;
- second folding means for pivotally mounting said second rake attachment means to said tool bar about a second axis between a downward operative position and a raised transport position;
- second control means for selectively moving said second rake attachment means and said second rake means between said downward operative position and said raised transport position;
- and
- a first invertible vertical adjustment means for selectively adjusting the vertical position of said first rake means with respect to said tool bar.
