Abstract
A crop raking apparatus having a pair of arms pivotally attached along the vertical axis to a frame. A side delivery type rake having rotatable radially extending teeth is attached to each of the arms. A mechanism is provided for pivoting each one of the rakes about a substantially horizontal axis from a deployed raking position when the respective arm is out to an upper transport position when the respective radial arm is pivoted inwardly. The arms are connected together to the frame by link members which are powered by a hydraulic cylinder.
Claims9
Crop raking apparatus comprising:
- a frame adapted to be attached to a prime mover;
- wheel unit means operatively attached to said frame for permitting said frame to be towed from place to place;
- a first arm pivotally attached to said frame about a first vertical axis;
- a second arm pivotally attached to aid frame about a vertical axis;
- a first elongated member disposed in a telescoping relationship with said first arm;
- means for permitting said first elongated member to rotate with respect to said first arm;
- a second elongated member disposed in a telescoping relationship with said second arm;
- means for permitting said second elongated member to rotate with respect to said second arm;
- first raking means operably attached to said first elongated member for raking cut crops into a windrow;
- second raking means operably attached to said second elongated member for raking cut crops into a windrow;
- first link means operably connected to said frame for pivoting said first arm, said first elongated member and said first rake means between an inner pivotal position and an outer pivotal position;
- first rotating means for rotating said first elongated member and said first rake means between a transport position when said first arm, said first elongated member and said first rake means are in the outer pivotal position thereof whereby said first rake means engages and windrows cut crops lying in a field;
- second link means operably connected to said frame for pivoting said second arm, said second elongated member and said second rake means between an inner pivotal position and an outer pivotal position;
- second rotating means for rotating said second elongated member and said second rake means between a transport position when said second arm, said second elongated member and second rake means are in the inner position thereof and a second operative position when said second arm, said second elongated member and said second rake means are in the outer pivotal position thereof whereby said second rake means engages and windrows cut crops lying in a field;
- and
- power means for selectively pivoting said first and second link means.
