Abstract: An adjustable coupling assembly and drain inlet combination for adjusting the height of the drain inlet for draining a fluid from an area is disclosed. The assembly includes a first tubular cylinder having a first end which is constructed to be attached to the inlet of drain tile, and a second tubular cylinder having a first end which is constructed to be attached to the discharge of the drain inlet. One of the tubular cylinders has an end which is constructed to extend into the other tubular cylinder. A spiral groove on one of the tubular cylinders extends over a substantial portion of the length of that cylinder, and at least one projection is positioned on the other tubular cylinder and is positionable to extend into the spiral groove whereby when one of the tubular cylinders is rotated relative to the other tubular cylinder, the projection moves along the spiral groove, to adjust the total combined length of the first and second tubular cylinders and the height of the drain inlet.

Abstract: Repair of a broken finger of a harvester reel pickup tine is accomplished by positioning a repair finger having a cavity over the broken finger stub so that the broken finger stub of the harvester reel pickup tine is received in the cavity of the repair finger, and the repair finger is then fastened adjacent one end to the pickup tine when the broken finger stub is in the cavity.

Abstract: A tip for the leading end of a crop divider of a combine corn head comprises a tip body of a durable low friction polymer which covers the snoot of the crop divider to reduce the incidents of clogging of the combine head as the head is advanced through the crop.
