A crop feeding roller for a header includes a plurality of finger units within the roller each having a pair of fingers projecting outwardly for engaging crop outside the peripheral wall of the roller. The peripheral wall has opposed finger guide holes associated with the pair of fingers. Each finger unit including an inner member carrying the fingers and containing an elongate guide slot transverse to the axis of the roller and a stationary guide member within the guide slot at a position within the roller arranged to cause the inner member with the fingers of each of the finger units to reciprocate during the rotation of the roller. The guide slot is shaped with at least one curved lobe to one side of a transverse center section so that the slot can be S-shaped or C-shaped to improve the dwell time and swept area obtained by the finger movement.

The center sickle overlap arrangement of a sickle type mower for a cutter bar that include a pair of sickles for reciprocating motion where each sickle is essentially half the length of the cutter bar for reduced forces and vibrations for high speed cutting. In the center, the sickle blades overlap at only guard and the blade of one sickle is inverted and co-operates with a top ledger surface of the associated guard so that both the blades are in proper shearing arrangement with the respective guard ledgers. Further the top ledger surface is adjustable to allow clearance adjustment to ensure tight clearance between all sickle cutting surfaces and guard ledgers. Further the arrangement ensures that all crop is cut between sickle sections and guard ledgers rather than between a pair of sections on the opposing sickles.

A forage conditioner for conditioning cut crop material from a forage harvester includes a fixed bottom fluted roller carried in end housings and a top fluted roller which is pivotally mounted on the housings by a linkage pivotal relative to the housing about an axis lying in a plane at right angles to the roller axes so that the top roller is liftable from crushing position against the bias of a spring extending along the top roller. Flutes on the rollers are arranged with a first surface on one side which extends substantially radially outwardly to an apex and a second surface which has a first portion parallel to a tangent of the roller and a second portion inclined inwardly to the roller surface at an angle significantly less than 90 degrees. The bottom roller is arranged with the first surfaces leading to carry the crop into the area between the rollers and the top roller is arranged with the first surface trailing. Thus the first surface of intermeshing flutes pass through a condition in which the first surfaces are substantially parallel and on opposite sides of a line joining the centers of the rollers to provide an effecting conditioning action on the crop.

A hand tool is disclosed for installing mallable rivets into a workpiece and for removing such rivets. The hand tool comprises a generally C-shaped body that has a clamp sleeve and a coaxially rivet forming member extending towards a coaxially located punch member. A workpiece is placed between the clamp sleeve and the punch member and the clamp secures the workpiece against the punch member. If a rivet is to be removed, the rivet forming member is retracted and the punch member is advanced to remove a rivet. If a rivet is to be installed, the punch member is partially retracted and the head of the rivet is rested thereon, then the rivet forming member is advanced against an end portion of the rivet extending from the opposite side of the workpiece.

The adjustment between the stub guards of a sickle knife arrangement of a crop cutting apparatus is improved by the provision of an adjustment plate which is positioned between the upper stub guard and the support bar. The upper and lower stub guards are clamped onto the support bar by carriage bolts with the lower stub guard engaging against the under surface of the support bar and the upper stub guard engaging against the upper surface of the adjustment plate. The spacing and orientation of the adjustment plate relative to the support bar is adjusted by the three set screws which are threaded into the adjustment plate and engaged against the upper surface of the support bar. The adjustment technique is simple, requires few parts and avoids the necessity for shims.
