The planter assembly comprises a parallel link having link arms extending between a mounting bracket and a 5 link bracket and pivotally connected to the mounting bracket and the link bracket. The mounting bracket is fixable to a plough frame, and the link bracket is moveable through a plane formed by the parallel link. The planter assembly also includes a jump arm arrangement joining a wheel to the parallel link, with the wheel is arranged to follow a surface contour and thereby cause movement of the link bracket through the plane, and a 10 locking mechanism to selectively restrain movement of the jump arm arrangement relative to either the link bracket or to one of the link arms.2/5 ~- C\ CO --- - -----a, a, oo 0 , co LO) CO Nl l C\ CO CO CO LO) C\J (.0~ a, N0 C\J 0)o 0) \(
