Claim of US Patent No. 10,216,156

1. A header assembly for attachment to a feeder house of a combine harvester for movement in a forward working direction across a field carrying a standing crop to be harvested, the header assembly comprising:a header comprising:
a header frame;
a sickle cutter bar carried across a front of the header frame for cutting standing crop;
a reel for carrying the crop over the cutter bar;
a crop transport device for transporting the crop inwardly from either end of the header to a collection location for feeding to the combine harvester;
a mounting arrangement for mounting the header frame on the feeder house of the combine harvester;
first and second ground engaging gauge wheels on the header frame one on each side of the feeder house;
the ground engaging gauge wheels being mounted on the header frame at a position spaced rearwardly of the cutter bar;
first and second adjustable links for adjusting the height of the first and second gauge wheels respectively relative to the header frame in response to a height input to adjust a cutter bar height;
an angle adjustment member for tilting the header frame forwardly and rearwardly about an axis transverse to the forward working direction relative to said mounting arrangement in response to an angle input to adjust an angle the header;
wherein the adjustment of the adjustment member to adjust the angle of the header also changes the height of the cutter bar and also the adjustment of the first and second adjustable links to adjust the height of the cutter bar also changes the angle of the header;
a control system operable by a driver including a driver interface arranged for input by the driver of:
a first manually operable input operable by the driver acting to set a value of required height of the cutter bar from the ground;
and a second manually operable input operable by the driver acting to set a value of required angle of the header relative to the ground about said axis;
the control system including a program which is responsive to the first manually operable input for generating both said height input to said first and second adjustable links and said angle input to said angle adjustment member to automatically attain said set value of required height of the cutter bar from the ground; and
the program of the control system also being a responsive to the second manually operable input for generating both said height input to said first and second adjustable links and said angle input to said angle adjustment member to automatically attain said set value of angle of the header relative to the ground about said axis.
