ADJUSTABLE REEL FOR A HARVESTER PLATFORM Abstract of the Disclosure A self-propelled combine has a forward transversely elongated cutting platform with a cutting mechanism along its leading edge and a pickup type reel spanning the width of the platform above the cutting mechanism. The reel is carried between a pair of vertically adjustable arms having quadrant ttype support members at their forward ends and carrying transverse pivots on which adjustable support elements are swingable and lockable to the support member by a locking device associated with the quadrant. The adjustable elements in turn support the reel shaft, which is driven through a chain drive by hydraulic motor attached to the adjustable element. A plurality of transversely spaced spiders are attached to the shaft and carry rockshafts at their outer ends, which are connected to eccentric spiders at the opposite ends of the reel via crank arms, the eccentric spiders also being journaled in the aajustable members. A plurality of fingers depend from the respective rockshafts and the rockshafts are rocked during rotation of the reel so that the fingers maintain a constant attitude relative to the ground. The fingertips gener- ate a cylinder that is coaxial with the pivot axis for the adjus- table element, and by rocking the adjustable element about the pivot, the attitude of the pickup fingers can be changed without changing the position of the cylinder generated by the fingertips.
