ABSTRACT:
A soil cultivating implement has soil working members mounted for rotation about corresponding upwardly extending axes. A soil working tool, preferably one or more tines, is connected to a support of the soil working member by at least one quick release fastener. The tool or tine can be a torsioned spring steel strip or a rod that has a spring coil. Each tine can have one or more operative soil contacting ends that are spaced apart from one another. When the operative ends are located one above the other, the soil working member can work deep in the soil. The fastener can be a pin that extends horizontal and at right angles to the axis of rotation of the soil working member so that the operative ends can pivot to some extent about the fastener. The ends of each tool or tine can extend in different directions from one another and tines in pairs can be mounted on the same support. The support can include arms pivoted to the fastening portions of the tines by spaced apart pins. Also, the support can be a sleeve hub that is received in a hollow frame portion.
