Abstract

A harvesting platform is connected to a combine for movement with the combine over the ground surface. The harvesting platform includes a cutter bar that cuts a crop being harvested, and a reel that presses the crop against the cutter bar during harvesting. The cutter bar moves between a cutter bar harvesting position and a cutter bar transport position, and the reel moves between a reel harvesting position and a reel transport position. A controller receives a first signal from a user via a user interface, sends a second signal to the cutter bar to move the cutter bar between the cutter bar harvesting position and the cutter bar transport position in response to the first signal, and send a third signal to the reel to move the reel between the reel harvesting position and the reel transport position in response to the first signal.

First claim

What is claimed is:

1. A harvester comprising:
a combine including
a prime mover operable to move the combine over a ground surface, and
a user interface configured to be engaged by a user and configured to send and receive signals, and
a feeder house defining a center line;

a harvesting platform connected to the combine for movement with the combine over the ground surface, the harvesting platform including
a cutter bar configured to cut a crop being harvested, the cutter bar moveable between a cutter bar harvesting position and a cutter bar transport position,
a reel configured to press the crop against the cutter bar during harvesting, the reel moveable between a reel harvesting position and a reel transport position; and
a first section connected to the combine, the first section having a first side and a second side opposite the first side, the first section extending along a first section plane that is substantially parallel to the ground surface;
a second section connected to the first side of the first section, the second section being rotatable with respect to the first section within a range of angular positions; and
a locking mechanism configured to retain the second section in a position with respect to the first section while the locking mechanism is activated, and configured to permit movement of the second section with respect to the first section while the locking mechanism is deactivated, and

a controller configured to
receive a first signal from the user interface,
send a second signal to the cutter bar to move the cutter bar between the cutter bar harvesting position and the cutter bar transport position in response to the first signal,
send a third signal to the reel to move the reel between the reel harvesting position and the reel transport position in response to the first signal,
receive a fourth signal indicative of the position of the second section, and
send a fifth signal to the locking mechanism to deactivate the locking mechanism in response to the position of the second section being at a positive non-parallel angle with respect to the first section plane.

2. The harvester of claim 1 , wherein the harvesting platform further comprises a gauge wheel configured to engage the ground surface as the harvesting platform moves over the ground surface, the gauge wheel moveable between a gauge wheel harvesting position and a gauge wheel transport position,
wherein the controller is further configured to send a sixth signal to the gauge wheel to move the gauge wheel between the gauge wheel harvesting position and the gauge wheel transport position in response to the first signal.

3. The harvester of claim 1 , wherein the controller is configured to receive a sixth signal from the reel indicative of a current reel position prior to sending the third signal to the reel, such that if the sixth signal indicates that the reel is in the reel harvesting position, the third signal instructs the reel to move to the reel transport position and if the sixth signal indicates that the reel is in the reel transport position, the third signal instructs the reel to move to the reel harvesting position.

4. The harvesting platform of claim 1 , wherein the range of angular positions is a first range of angular positions, the locking mechanism is a first locking mechanism, and the position is a first position, the harvesting platform further including
a third section connected to the second side of the first section, the third section being rotatable with respect to the first section within a second range of positions, and
a second locking mechanism configured to retain the third section in a second position with respect to the first section while the second locking mechanism is activated and configured to permit movement of the third section with respect to the first section while the second locking mechanism is deactivated,
wherein the controller is further configured to receive a sixth signal indicative of the second position and configured to send a seventh signal to the second locking mechanism to deactivate the second locking mechanism in response to the second position being at a positive non-parallel angle with respect to the first section plane, and
wherein the third section is configured to move toward the first section plane in response to gravity while the second locking mechanism is deactivated.

5. The harvesting platform of claim 4 , wherein the controller is configured to send eighth signal to the first locking mechanism to activate the first locking mechanism and to send a ninth signal to the second locking mechanism to activate the second locking mechanism in response to an operator selecting a transport operation of the combine,
wherein the controller is configured to continue sending the eighth signal to the first locking mechanism to maintain activation of the first locking mechanism in response to the first position being at a negative non-parallel angle with respect to the first section plane, and is configured to continue sending the ninth signal to the second locking mechanism to maintain activation of the second locking mechanism in response to the second position being at a negative non-parallel angle with respect to the first section plane, and
wherein the controller is configured to continue sending the eighth signal to the first locking mechanism to activate the first locking mechanism in response to the first position being substantially parallel to the first section plane, and is configured to continue sending the ninth signal to the second locking mechanism to activate the second locking mechanism in response to the second position being substantially parallel to the first section plane.

6. The harvesting platform of claim 1 , wherein the locking mechanism includes a cylinder, an accumulator and a valve fluidly positioned between the cylinder and the accumulator, and
wherein while the locking mechanism is activated, the valve is closed to inhibit fluid flow between the cylinder and the accumulator, and while the locking mechanism is deactivated, the valve is opened to permit fluid flow from the cylinder to the accumulator.

7. A harvester comprising:
a combine including
a prime mover operable to move the combine over a ground surface,
a user interface configured to be engaged by a user and configured to send and receive signals,
a feeder house defining a center line; and

a harvesting platform connected to the combine for movement with the combine over the ground surface, the harvesting platform including
a cutter bar configured to cut a crop being harvested,
a reel configured to press the crop against the cutter bar during harvesting, the reel moveable between a reel harvesting position and a reel transport position,
a gauge wheel configured to engage the ground surface as the harvesting platform moves over the ground surface, the gauge wheel moveable between a gauge wheel harvesting position and a gauge wheel transport position,
a first section connected to the combine, the first section having a first side and a second side opposite the first side, the first section extending along a first section plane that is substantially parallel to the ground surface;
a second section connected to the first side of the first section, the second section being rotatable with respect to the first section within a range of angular positions; and
a locking mechanism configured to retain the second section in a position with respect to the first section while the locking mechanism is activated, and configured to permit movement of the second section with respect to the first section while the locking mechanism is deactivated; and

a controller configured to
receive a first signal from the user interface,
send a sec
