A harvesting reel assembly for a header of an agricultural harvester is disclosed. The harvesting reel assembly includes a central rotatable shaft, a plurality of support members, a cam assembly and an extendable reel arm. The plurality of support members extend widthwise across the reel assembly and connect to the central rotatable shaft for rotation therewith. The cam assembly guides rotation of the plurality of support members. The extendable reel arm includes a first end engaged with the central rotatable shaft for rotation therewith. The extendable reel arm also includes a distal end opposite the first end connected to one of the plurality of support members.

A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. The cutter bar is mounted on the frame at spaced positions by spring blades attached to a fixed beam at the rear which allow up and down flexing movement of the cutter bar relative to the draper engagement member. At the center discharge the cutter bar is carried on shorter blades which are carried on a beam in front of the front draper roller. The small amount of flexing of the cutter bar combines with a balanced three piece header frame to provide effective ground following.

An agricultural harvester is disclosed. The agricultural harvester comprises a header and a cab for an operator of the harvester. The header includes a frame, a support arm connected to the frame and a harvesting reel assembly. The harvesting reel assembly includes a central rotatable shaft connected to the support arm, a reel member extending widthwise across the harvesting reel assembly and connected to the central rotatable shaft for rotation therewith, and a first cam assembly rotatable about a first end of the central rotatable shaft. The first cam assembly includes a first cam plate, a first non-circular cam track for guiding rotation of the reel member and a first adjustor. The first adjustor is operatively engaged with the first cam plate and pivotably connected to the support arm for adjusting a rotational position of the first cam assembly relative to the central rotatable shaft.

A cam assembly is provided for a pick-up reel of an agricultural harvester. The cam assembly includes a cam track, a roller bearing assembly, a crank arm, and a biasing member. The roller bearing assembly includes a baffle and first and second cam followers. The first and second cam followers are each mounted to the baffle in spaced apart relation and engaging the cam track. The crank arm is for mounting to the pick-up reel. The biasing member biases the roller bearing assembly relative to the crank arm.

A reel of a harvester including a cutter bar includes a plurality of reel bats which are pivotal so as to vary the angle of the fingers about the bat axis as the reel rotates and an end shield plate mounted on the reel at the end of the reel. The end plate has a peripheral edge located radially inward of an outer tip of the fingers with an apex at each of the bats and portions which are recessed from a straight line joining the apexes to allow rotation of the finger around the bat axis without contacting the peripheral edge. Each of the endmost fingers of the bats has a base which is axially inside the end plate and is bent longitudinally of the reel to define an outer tip which is axially spaced from the base to a position beyond the radial plane of the end plate.

A reel includes a plurality of bats and an end shield plate mounted on the end of the reel at the crop divider which has a peripheral edge radially inward of an outer tip of the fingers with an apex at each of the bats and portions which are recessed from a straight line joining the apexes. Each of the endmost fingers of the bats has a base which is axially inside the end plate and is bent longitudinally of the reel to define an outer tip which is axially spaced from the base to a position beyond the radial plane of the end plate. A plurality of molded paddle blades are mounted to project outwardly from the end surface to clear crop away from the space between the outer face of the end plate and the divider.
