Abstract
A novel solution for changing sweeps or knives on a cultivator or other soil working tool is the subject matter of the present invention. In today's farming world, where labor is at a premium and time is of the essence, a sole operator or farmer in preparing the fields for planting, summer fallow or other operations will sometimes need to change the sweeps or knives which till the ground several times for different crops or operations. The novel invention herein provides for an apparatus for quickly removing the sweeps (2) on cultivator shanks and replacing them with other soil openers of different width or configuration. A simple press button (7) releases the sweep (2) from an adapter bolted to a standard cultivator shank. The present invention eliminates the problem of sweeps falling off shanks due to lack of friction or difficulty in removing sweeps because of over friction.
