ABSTRACT:
An assembly and method are provided for removing and installing a reciprocating sickle knife from or on a sickle knife holder. The sickle knife comprises a plurality of sickle knife sections attached to a knife back bar with spaced, repeating pattern or recurrent fasteners. The sickle knife is protected from damage by a plurality of sickle guards attached to the sickle knife holder. The assembly comprises first and second rotatable sprockets secured to a support member. The sprockets are interconnected by an endless chain which has drive lugs that will drivably engage recurrent fasteners on the sickle knife. In the preferred embodiment, two adjacent sickle guards are removed allowing the assembly to be installed on the sickle knife holder such that the chain is positioned adjacent the recurrent fasteners. A power source such as a hand crank, then drives or rotates the sprockets to drive the chain so that the recurrent fasteners are engaged with the drive lugs sequentially, displacing the sickle bar.
