Abstract

An apparatus 30 has an elongate body 32 and spaced booms extending downstream from the body 32 for operation on a field having a plurality of rows having mounds 4 to 12 and furrows 14 to 22. Blades 34 and 36 for moving about 50 mm of material 24 and a thin layer of soil inwardly from the mounds 4 to 10 are fixed to respective shank supports 38 and 40 which are joined to the body 32. Blades 42 and 44 for moving the soil outwardly from respective mounds 4,6,8 and 10 are also fixed to the supports 38 and 40. The blades 42 and 44 are positioned about 50 mm lower than the blades 34 and 36. The apparatus 30 has two sets of blades 34 and 36 and two sets of blades 42 and 44 positioned next to each other. Fixed to short booms are listers 46 for moving the material 24 in furrows 16 and 20 onto mounds 4 to 10. Fixed to long booms are listers 48 for reforming the mounds 4 to 10 by moving soil over the material on the mounds 4 to 10 and shaping the mounds at the same time.
