Abstract
A rake implement includes a first arm and a second arm. A first linkage system interconnects and is selectively configurable to position the first arm in a travel position, a first operating position, and a second operating position. A second linkage system is selectively configurable to position the second arm in a travel position, a first operating position and a second operating position. The first arm and the second arm may be positioned in different respective operating positions to provide different rake configurations for different field conditions.
Claims22
A rake implement for moving cut crop material laterally to form a windrow, the rake implement comprising:
- a frame having a tongue configured for attachment to a tow vehicle, wherein the frame extends along a central longitudinal axis parallel with a direction of travel, with the central longitudinal axis bisecting the frame to define a first lateral side of the frame and a second lateral side of the frame;
- a first arm including a forward end and a rearward end relative to the direction of travel, wherein the first arm supports a first rake system;
- a first linkage system interconnecting the frame and the first arm;
- wherein the first linkage system is selectively configurable to position the first arm relative to the frame in a travel position of the first arm in which the first arm is positioned to reduce an implement width on the first lateral side of the frame for transport;
- wherein the first linkage system is selectively configurable to position the first arm relative to the frame in a first operating position of the first arm in which the first arm is substantially non-parallel with the central longitudinal axis and extends away from the frame at an acute angle relative to the central longitudinal axis;
- wherein the first linkage system is selectively configurable to position the first arm relative to the frame in a second operating position of the first arm in which the first arm is substantially non-parallel with the central longitudinal axis and extends away from the frame at an acute angle relative to the central longitudinal axis;
- wherein the acute angle of the first arm when disposed in the first operating position of the first arm is different than the acute angle of the first arm when disposed in the second operating position of the first arm;
- wherein both a rearward end and a forward end of the first rake system are positioned on the first lateral side of the frame when the first arm is disposed in the second operating position of the first arm;
- a second arm including a forward end and a rearward end relative to the direction of travel, wherein the second arm supports a second rake system;
- a second linkage system interconnecting the frame and the second arm;
- wherein the second linkage system is selectively configurable to position the second arm relative to the frame in a travel position of the second arm in which the second arm is positioned to reduce implement width on the second lateral side of the frame for transport;
- wherein the second linkage system is selectively configurable to position the second arm relative to the frame in a first operating position of the second arm in which the second arm is substantially non-parallel with the central longitudinal axis and extends away from the frame at an acute angle relative to the central longitudinal axis;
- wherein the second linkage system is selectively configurable to position the second arm relative to the frame in a second operating position of the second arm in which the second arm is substantially non-parallel with the central longitudinal axis and extends away from the frame at an acute angle relative to the central longitudinal axis;
- wherein the acute angle of the second arm when disposed in the first operating position of the second arm is different than the acute angle of the second arm when disposed in the second operating position of the second arm;
- wherein both a rearward end and a forward end of the second rake system are positioned on the second lateral side of the frame when the second arm is disposed in the second operating position of the second arm;
- and
- wherein the rearward end of the first rake system is positioned on the second lateral side of the frame and the forward end of the first rake system is positioned on the first lateral side of the frame when the first arm is disposed in the first operating position of the first arm.
