ABSTRACT:
A soil cultivating implement comprises a hollow portion which rotatably supports a row of substantially vertical shafts, each shaft carrying a corresponding soil working member at its lower end. Each soil working member comprises a tine holder having two laterally extending limbs which are both curved rearwardly with respect to the intended direction of operative rotation thereof and define shallow U-shaped channels, the outer end of each limb being integrally provided with a corresponding tine carrying sleeve in which is snuggly and slidably received a relatively rigid tine composed of spring-type steel. The tines are formed from rod material of uniform square cross section and each of them has, at a radially innermost corner, a notch which can be brought into register with any one of four spaced bores in the carrying sleeve, a retaining member, a pin tube, on the like being entered through a selected bore and the corresponding notch to retain the tine in the desired position of downward projection from the sleeve. With the tines becoming shorter due to wear, their original effective lengths can be restored by displacing them downwardly in the sleeves. This permits the maximum working depth of the implement to be attained without having to replace the tines when they become initially worn. Alternative embodiments are described in which the tines constitute strip-shaped bars of elongated rectangular cross section, each of which has a plurality of notches or holes for cooperation with a single bore and a retaining pin, tube or the like.
