Each stub shaft carries a pair of spring tines with the springs wrapped around the shaft and an inclined portion of the tine extending forwardly from the angled shaft and therefore at an angle to the transverse support member. Two such members can be mounted on pivot arms to provide a transverse reciprocating working action of the tines. This harrow element can be mounted upon support arms pivoted from a draw bar and carried on ground wheels which may be simple depth wheels or may form packer wheels. In an alternative arrangement the packer wheels and harrow element are mounted on a subframe which can be reversed so that the packers operate in advance of the harrow element.
