-27- "SICKLE KNIFE REPLACEMENT ASSEMBLY" ABSTRACT OF THE DISCLOSURE Conventionally, rivets are sheared off by hand whereupon a rivet shank removal tool is engaged around the knife and align so that the punch aligns with the rivet shank. A nut is then tightened with a wrench thus pushing the rivet shank out of the hole and when all rivets have been removed, the old knife can be removed also. A new knife is then positioned upon the cutter bar, rivets are installed and the heads riveted over, a labor intensive, time consuming operation. With the present device, the knife assembly is engaged across a portable frame carrying a tool group and one end of the knife assembly is engaged between manually operated roll- ens so that it can be adjusted lengthwise to place the knife being replaced, successively in the correct post- lion with a shear tool which shears off the knife and rivet heads, a punching tool to remove the shanks and a riveting tool to rivet over the heads of rivets holding a new knife in position. All of these tools are hydraulic or pneumatically operated.
