A ground working implement assembly having a handle (11) and a plurality of implement heads (13, 14, 15, 16 and 17). Each implement head has a ground working member (13A, 14A, 15A, 16A and 17A) and a tang (13B, 14B, 15B, 16B and 17B). One end of the handle (11) has a socket assembly (20) adapted to receive the tang of an implement head. A retaining pin (31) removably secures the tang of an implement to the socket assembly (20) when the tang is received thereby. The implement heads (13, 14, 15, 16 and 17) are configured so that they are nestable with each other for storage.
