A harvester reel adjusting and locking mechanisms for positioning the bearing carrier at each end of the reel axle at a selected distance along the support arm on which it is slidable. The carrier is provided with holes which are capable of registering with a series of closely spaced holes in the outer end region of the support arm. An operating tool having a vertical shank portion serves to lock the carrier in an adjusted position when such shank is projected through one of the holes in the carrier and a selected registering hole in the support arm. A radial displacement cam is disposed on the shank portion and is of such extent that when the shank portion is positioned in a hole immediately forwardly or rearwardly of the carrier and then rotated through an angle of 180.degree., the carrier will be shifted in a forward or a rearward direction to a degree equal to the center-to-center distance between adjacent holes, after which the shank may be placed in the hole in the carrier and a registering hole in the support arm to lock the carrier in position. A lateral leg on the shank constitutes a lever by means of which torque may be applied to the shank for rotational purposes. By repeating the process, the carrier may be "walked" or indexed along the support arm in either a forward or a rearward direction.
In an agricultural implement, the combination with an adjustable bearing support for one end of a harvester reel associated with a combine platform, said support embodying an elongated reel-supporting arm having a longitudinal row of closely and equally spaced reaction holes formed therein, and an open-ended tubular sleeve-like carrier slidable longitudinally on said arm, a reel bearing being fixedly mounted on the carrier, an operating tool for effecting step-by-step indexing movements of the carrier on the supporting arm in increments of movement equal to the center-to-center distance between adjacent reaction holes, said tool including a shank adapted to be projected into a reaction hole next adjacent to either end of the carrier and exteriorly of the latter, a radially extending cam on said shank in the medial region thereof and effective when the shank is disposed in said next adjacent reaction hole to engage the adjacent end of the carrier and, by a camming action, index the carrier bodily throughout one increment of movement, and a crank arm on said shank for manually applying torque to the shank to rotate the same.
