Soil cultivating implements

Claim 2

A soil cultivating implement comprising a frame and a plurality of soil working members journalled on an elongated portion of said frame, said portion extending transverse to the direction of implement travel, supporting roller means being positioned to the rear of said portion and interconnected to said frame with adjusting means that regulates the working depths of the soil working members, pivotal means located on said frame portion and said pivotal means comprising two spaced coupling points on top of said frame portion for connection to further implement means, each point defining an upwardly extending axis about which said implement means is pivotable when connected to that point, said two coupling points being located in advance of said roller means with respect to the direction of travel, and above said soil working members, said points being positioned at opposite sides of the center of said frame portion.

Claim 3

An implement as claimed in claim 1, wherein further respective implements are connected to said two points by bars that extend rearwardly from said points to the further implements positioned rearwardly of the roller means.

Claim 4

An implement as claimed in claim 2, wherein each coupling point includes a bracket mounted on top of said frame portion, said bracket being positioned to receive a pin that defines an upwardly extending axis.

Claim 5

An implement as claimed in claim 3, wherein at least one of said further implements is structured to deliver material into and/or onto the ground, said one implement having an arched draw bar that is connected to its respective coupling point.

Claim 6

A combination as claimed in claim 4, wherein each further implement has an arched draw bar located substantially centrally across the width of the further implement and two spaced apart ground wheels support that implement.

Claim 7

An implement as claimed in claim 5, wherein each further implement comprises a hopper that extends transverse to the direction of travel, said hopper being bevelled at its adjacent ends and at the front thereof.

Claim 8

An implement as claimed in claim 6, wherein the bottom of each hopper has a plurality of material delivery members movably connected to it, means automatically raising said delivery members relative to the ground surface when said frame portion is raised by said lifting device.

Claim 9

An implement as claimed in claim 7, wherein said delivery members are carried on a common support of the further implement and said common support being displaceable upwardly against resilient opposition.

Claim 10

An implement as claimed in claim 8, wherein said common support is connected to a rocker which, in turn, is connected by said control member to an anchorage on said frame portion.

Claim 11

An implement as claimed in claim 9, wherein said anchorage is located adjacent said coupling point.

Claim 12

A soil cultivating implement comprising a frame and a plurality of soil working members journalled on an elongated portion of said frame, said members being mounted in a row and said portion extending transverse to the direction of implement travel, supporting roller means being positioned to the rear of said portion and interconnected to said frame with adjusting means that regulates the working depths of the soil working members, pivotal coupling means located on said frame portion and said coupling means comprising two spaced apart coupling points on top of said frame portion for connection to further implement means, each coupling point defining an upwardly extending axis to which said implement means is pivotable when connected to that point, said two coupling points being located in advance of said roller means with respect to the direction of travel and adjacent a plane containing the axes of rotation of said soil working members, said points being positioned at opposite sides of the center of said portion and at substantially equal distances from that center.

Claim 13

A soil cultivating implement comprising a frame and a plurality of soil working members journalled on an elongated portion of said frame, said members being mounted in a row and said portion extending transverse to the direction of implement travel, supporting roller means being positioned to the rear of said portion and interconnected to said frame with adjusting means that regulates the working depths of the soil working members, pivotal coupling means located on said frame portion and said coupling means comprising two spaced apart coupling points on top of said frame portion for connection to further implement means, each coupling point defining an upwardly extending axis to which said implement means is pivotable when connected to that point, said two coupling points being located in advance of said roller means with respect to the direction of travel and adjacent a plane containing the axes of rotation of said soil working members, said points being positioned at opposite sides of the center of said portion and at substantially equal distances from that center.
