ABSTRACT:
Detachable cultivator teeth shovels and the like are usually bolted to the implement shank and these bolts corrode or rust, or get clogged with dirt or become burred over thus making detachment extremely difficult. The present device includes a quickly attachable and detachable implement to a shank which includes pins extending through the shank and the implement and being engaged by keyhole wedge slots of a locking plate which pulls the implement tightly to engagement with the shank by slight downward movement of the plate, the keyhole slots of which engage over cut away portions near one end of the pins. A set screw screw threadably engages the plate and is then tightened so that the inner ends bears against the shank and holds the assembly firmly in position yet enables the implement to be detached readily and easily when desired.
