Abstract

A soil working implement has a row of soil working tools that displace soil rearwardly and laterally. A side-plate is pivoted to each side of the implement frame and positioned adjacent the outer ends of the row to arrest the lateral movement of the soil. An elongated supporting roller is located to the rear of the row to support the implement and further work the soil. Each side-plate has a lower rim that rides along the ground and a guide element is attached to the rear of the side-plate to extend inwardly towards an outer roller end. The element is preferably a blade that is inclined to displace soil arrested by the side-plate and prevent ridging. The blade can be integral or attached to the rim.

Claims

1. A soil cultivating implement comprising a plurality of soil working members that are arranged in a transverse row in side-by-side relationship, drive means connected to rotate said soil working members about upwardly extending shafts that define axes of rotation for said soil working members, an elongated ground engaging roller being positioned to the rear of said soil working members, said roller extending across the working width of said row of members, a side-plate being positioned adjacent an outer end of said row to arrest the lateral movement of worked soil, said side-plate being connected to the implement, soil guide means being positioned adjacent the rear of said side-plate and at least a part of said guide means extending towards an outer end of said roller, said guide means including an upper portion that is detachably connected to said side-plate and a lower blade that is inclined to said side plate and normally positioned adjacent the ground and between a lateral end of the roller and the rear of said side-plate, and an upper spring portion that spring-loads said guide means and is detachably connected to the rear of said side-plate, said blade being attached to the lower end of said spring portion and inclined to that portion.

2. An implement as claimed in claim 1 wherein said side-plate is connected to a frame for said working members in a manner to be relatively movable in a substantially vertical plane relative to said frame.

3. An implement as claimed in claim 1 wherein said side-plate comprises slide means along its lower edge which slides along the ground, the lowest part of said guide means being slightly higher than the bottom of the lower edge of said slide means where it slides along the ground.

4. A soil cultivating implement comprising a frame and a plurality of soil working members that are arranged in a transverse row in side-by-side relationship along the length of an elongated portion of said frame, drive means connected to rotate said soil working members about upwardly extending shafts that define axes of rotation for said soil working members, an elongated ground engaging roller being positioned to the rear of said soil working members, said roller extending substantially across the entire working width of said row of members, an upwardly extending side-plate being positioned adjacent an outer end of said row to cooperate with an adjacent said soil working member, said side-plate being pivoted to the frame portion, a spring-loaded soil guide element being detachably connected to the side-plate and positioned adjacent the rear thereof, a lower part of said guide element extending from the side-plate inwardly and towards an outer end of said roller, said guide element comprising a blade that is connected to the rear of said side-plate, said blade having a plane inclined from the horizontal at an angle of at least sixty degrees.

5. An implement as claimed in claim 4 wherein said side-plate is pivoted to said frame portion in a manner to be relatively movable in a substantially vertical plane relative to said frame portion.

6. An implement as claimed in claim 4 wherein said side-plate comprises slide means along its lower edge which slides along the ground, the lowest part of said guide element being slightly higher than the bottom of the lower edge of said slide means where it slides along the ground.
