An agricultural harvesting machine includes a feeder housing and a cutting platform. The cutting platform includes a center platform section carried by the feeder housing. A first wing platform section extends laterally from one side of the center platform section, and a second wing platform section extends laterally from another side of the center platform section. A height control system includes a lift cylinder coupled with the feeder housing, a first tilt cylinder coupled between the center platform section and the first wing platform section, and a second tilt cylinder coupled between the center platform section and the second wing platform section. The lift cylinder, first tilt cylinder and second tilt cylinder are automatically adjusted independent from each other during harvesting operation of the cutting platform.

A cutting platform for use with an agricultural harvesting machine includes a plurality of platform sections positioned in end-to-end juxtaposed relation to each other. At least one platform section includes a frame, a plurality of float arms movably coupled with the frame, an endless belt carried by the plurality of float arms, and a cutterbar assembly carried by the plurality of float arms and movable in a localized manner in upwards and downwards directions.

A cutting platform for use with an agricultural harvesting machine includes a plurality of platform sections, with each platform section including a leading edge. At least one platform section includes a cutterbar assembly movable in a localized manner in upwards and downwards directions, an endless belt, and a plurality of belt guides positioned partially above the endless belt adjacent the leading edge. The belt guides are movable relative to each other.

A harvesting assembly is provided with a transverse feed auger for directing harvested crop material into a feederhouse. The feed auger is also provided with retractable fingers. The retractable fingers are freely rotatably mounted on a finger timing shaft located in the feed auger. A feed auger torque sensor is mounted to the feed auger and communicates an actual feed auger torque signal to a controller. The controller is provided with a memory having a maximum desired feed auger torque signal. When the actual feed auger torque signal exceeds the maximum desired feed auger torque signal, the feed auger drive is disengaged. A timing shaft torque sensor is mounted to the finger timing shaft and communicates an actual timing shaft torque signal to the controller. The memory of the controller is provided with a maximum desired timing shaft torque signal. When the actual timing shaft torque signal exceeds the maximum desired timing shaft torque signal a brake is applied to the feed auger.

A pickup reel for a harvesting platform including a reel support structure with a reel shaft rotatably supported thereon. A plurality of radially extending arms are mounted to the reel shaft and a plurality of transverse rockshafts are mounted to the radially extending arms and are axially offset and parallel to the reel shaft and span the width of the platform. Radial fingers are mounted on each rockshaft. A cam is mounted to the support structure adjacent one or both ends of the rockshafts and defines an endless cam path about the reel shaft. A crank arm attached to each rockshaft carries a cam follower that engages the cam path for following along the path. The cam path is configured to cause the crank arms, and thus the rockshafts, to rotate about the respective rockshaft axis to vary the attitude of the fingers relative to the ground as the cam followers move along the cam path. The cam is segmented, having two or more cam segments joined together to form the endless cam path. The cam segments are joined together by removable fasteners to enable one segment to be removed and replaced to either vary the cam path or to replace a worn cam segment.

A pickup reel is provided with an anti-wrap extension that can be easily mounted to one of the elongated tubes. The anti-wrap extension increases the size of the bat to prevent wrapping. The tine is provided with an upstanding projection having a mounting screw for securing the anti-wrap extension to the tine. In addition, the extension is provided with a downwardly projecting flange having mounting apertures into which the tines are inserted.

A combine having a transverse threshing cylinder and concave and an axial separator. The axial separator comprises a pair of side-by-side axial separator units each having a rotor and a casing in which the rotors are housed. Each axial separator units is provided with three detachable covers having inwardly projecting spiral vanes. The covers are axially arranged and the first cover is adjacent to the transverse threshing cylinder and concave. The first cover is provided with at least five spiral vanes. The first vane has an angle of inclination to the transverse axis of approximately forty-five degrees; the second, third and fourth vanes have an angle of inclination of approximately thirty degrees; and the fifth vane has an angle of inclination of approximately twenty-five degrees. In small grains, such as rice, the second and third covers each have at least four vanes all with an angle of inclination of approximately twenty degrees. In corn, the second and third covers each have at least four vanes all with an angle of inclination of approximately ten degrees. The second and third covers are designed to be interchangeable depending on crop.

An axial separator for an agricultural combine. The axial separator comprises two side-by-side axial separator units. Each axial separator unit has a rotor that rotates in and is housed in a casing. The bottom rear of the axial separator is open and forms a discharge area into which straw falls. To move evenly distribute the straw along the width of the combine a wedge shaped deflector is positioned in the last quarter of the discharge area below and between the rotors.
