ABSTRACT:
An implement has rotatable soil working members that include tines mounted on supports. Each support is formed by resilient interengaging strips that are clamped between an upper hub flange and a lower locking plate, the latter being connected to an upwardly extending driven shaft. The strips are bent to form rectilinear bases and outwardly extending arms of inner and outer pairs of strips. The outer ends of the arms are secured by respective upper and lower clamping plates which, together with the strip ends, form holders for tine fastening portions. When the soil working member is rotated about an axis defined by the shaft, the tines can deflect in directions tangential to the shaft and mitigate damage if any obstacle is encountered.
