A seedbed cultivator may comprise a main frame 3 which may be coupled to a tractor three point linkage (Fig 1, 2). A series of discs 19, 27, 28 may be attached to respective leg brackets 18, 20, said discs acting to cut ground and guiding the cultivator, with discs 27, 28 also acting to guide soil along the device. Below and to the rear of disc 28 a leading edge having teeth 13 and vertical swords 23 on one of a series of wing like members 4 starts to lift the soil disturbed by the discs. The partly fragmented soil rises up the wings 4 passes over the mid-section 6 and drops away over the trailing edge 7 onto a lower wing 8 that is wider than the upper wing. This lower wing may be fitted with teeth 14. Concave returns 9 on wings fold the soil inward, in line with with the midpoint of each of the pairs of the upper wings and in line with each of the sets of discs. A line of chisel like tines 16 and a series of rollers 17 may also be fitted to further aerate the tilth and then to consolidate it. The wings and rollers may be fitted to a main support arm 12 fitted with a shear bolt 25. The cultivator is intended to be used in zero till or low input cultivation and does not leave a furrow as it passes through the ground.
