A quick-change system for a sweep comprising:

• a cultivator shank,
• a sweep comprising a neck, the neck being configured for coupling the sweep to the cultivator shank, and
• a removable wedge,
• wherein the neck comprises at least one lug, attached to an inner surface of the neck, to be fitted into at least one hole of the cultivator shank,
• wherein the neck defines a transverse “C”-shaped profile that includes a pair of side flaps which guide the cultivator shank through the neck, and comprise bent portions at each end configured to clasp said removable wedge as it is inserted through an upper part of the neck, and
• wherein the removable wedge is configured to slide between the pair of side flaps along the cultivator shank in a longitudinal direction of the cultivator shank against the inner surface of the neck, as the at least one lug of the sweep is pressed into the cultivator shank and secures the position of the cultivator shank inside the sweep,
• such that the fitting of the at least one lug of the sweep in the at least one hole of the cultivator shank together with the removable wedge inserted in the neck retain and fasten the sweep to the cultivator shank.
