Harvester with automatic depth and level control

An apparatus configured to harvest crops as the apparatus moves in a direction of travel across a field, the apparatus comprising:

• a frame;
• a crop harvesting assembly attached to the frame and configured as a line of implements, the line being transverse to the direction of travel;
• a left ground contacting element;
• a first device disposed between the frame and the left ground contacting element, the first device being configured for adjusting a vertical position of a left side of the frame;
• a right ground contacting element;
• a second device disposed between the frame and the right ground contacting element, the second device being configured for adjusting a vertical position of a right side of the frame;
• wherein the first and second devices are independent operable,
• wherein adjustment of a vertical position of at least one of the left and right sides of the frame is configured to result in tilting the line of implements relative to a horizontal plane defined at a ground surface under the left and right ground contacting elements, and
• wherein relative positions of the frame and the crop harvesting assembly are maintained while the crop harvesting assembly tilts relative to the horizontal plane defined at the ground surface under the left and right ground contacting elements;
• and
• an axle carrying member having a first pivotal connection with the frame;
• wherein at least one of the ground contacting elements is mounted on an axle connected to the axle carrying member;
• wherein the axle carrying member has a second pivotal connection with a first end of the first device;
• and
• wherein a second end of the first device has a third pivotal connection with the frame.
