Abstract: Pruning plants that exude sticky sap may leave pruners gummed up and barely useable. Cleaning edged cutting tools presents injury risks to nursery and farm workers, so a need for rapid and effective cleaning machines exists. This pruner cleaning machine includes a motorized rotor assembly of scrubber discs facing each other and a helical center brush disposed between them. The scrubber discs include helical ramps and step faces at the ends of these ramps which conform to the ends of the helical scrubber, so that the spacing between the scrubber discs may be accurately controlled by the number of turns of the helical scrubber, including partial turns. The rotor may be reconfigured for various types of pruners by selecting from among various lengths of helical scrubbers. Properly configured, by using this machine and its inventive scrubbing rotor, gummed up pruners may be cleaned in seconds.
