Abstract: A ground engaging seed delivery device comprising an elongate support arm 8 pivotally mounted to a driving structure via a mounting structure 7 adapted to accommodate vertical linear displacement wherein the support arm has an offset coulter disc 3 fitted along the length thereof, a back swept seed delivery tube 2, followed by a packer wheel 4 and a ground engaging control arm 1 positioned to act between the coulter disc and packer wheel so as to follow a furrow formed by the coulter disc and prevent the furrow divot from either collapsing and/or being thrown prior to delivery of seed into the furrow such that the packer wheel can replace the divot immediately following delivery of seed to the furrow.

Abstract: A direct drill seeding unit comprising a coulter wheel (5), a pair of depth control wheels (7) and a splitter (9) where the main components of the seeding unit are pivoted on an elongate arm (1) which is connected to a common or main frame (3). The pivotal movement of the unit allows a gang of the seeding units to follow undulating land in a very faithful manner. Furthermore the splitter (9) is capable of variable height and angle relative to the ground level according to the vertical position of the elongate arm such that as the arm moves up the splitter shall automatically compensate by lowering in order to maintain contact with the soil. The adjustment of the splitter is effected by the trapezoid configuration of the 4 pivoting points and the "L" shaped common linkages (4).
