Abstract: A tool usable for removal and replacement of rivets in changing sickle section blades on equipment such as a combine, a mower, or the like. The tool includes an upwardly open column and a shaft assembly. The shaft assembly includes an elongate threaded shaft having a lower end installed in the column. A collar is threaded on the shaft and bears against the top end of the column. The length of the tool is adjustable by rotation of the shaft with respect to the collar to move the upper end of the shaft up or down. The upper end of the shaft has a working head to support the sickle section blade during a process of removing or applying a rivet. A removable anvil is inserted in the head of the shaft assembly for the process of attaching a new rivet. The column is pivotally mounted on a stand by a lever assembly to raise and lower the column to bring the head of the shaft assembly into and out of bearing engagement with the sickle section blade for purposes of working on the sickle section blade.
