  • Patent number: 6119791
    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.

  • Patent number: 5941316
    Abstract: A stalk puller and chopper assembly 10 drawn behind a tractor 11, the stalk puller and chopper assembly comprising a puller means in the form of a pair of contra-rotating rubber wheels 12 and 13 on a shaft 21. The wheels are located upstream of a feeder means comprising a pair of guide plates 14 and 15 and an array of toothed feeder blades 16 mounted on a feeder shaft 17. The guide plates co-operate with the wheels and the rotating feeder blades 16 to deliver stalks extracted by the wheels to a downstream chopper assembly 19 where chopper blades 18 on shaft 22 shred the stalks which are then discharged rearwardly at 20 in the form of mulch. As can be seen the stalks are controllably delivered sideways into the choppers. The clearance between the cutter blades 18 and the anvils of the toothed feeder blades is exaggerated in the drawings with the usual clearance being about 2 mm.

  • Patent number: 5941317
    Abstract: A row cultivator 10 is drawn behind a prime mover illustrated by the wheels 11 with rows defined by mounds illustrated in terms of the lines 12 before the cultivator and the reshaped mounds being illustrated by the lines 13 located behind the cultivator. As can be seen the rows before the cultivator include an irregularity. In this case there are wide rows shown at 14 and relatively narrow rows shown at 15. The cultivator 10 includes a fixed rigid tool bar 16 and a moveable tool bar 17 travelling behind the fixed tool bar 16 and pivotable relative thereto via connecting bars 18, 19 and 20. Where the rows to be reshaped are all evenly spaced the connecting bars 18, 19 and 20 would be positioned parallel to the rows. The moveable tool bar 17 is displaced to the left.
