Abstract
Cultivator apparatus comprises an elongate main frame and a plurality of cultivator sub-assemblies spaced along the length of the main frame and each including a sub-assembly frame. Respective linking means connect each of the sub-assembly frames to the main frame for independent floating movement of the sub-assembly frame with respect to the main frame while preventing tilting of the sub-assembly frame with respect to the main frame.
Claims5
Cultivator apparatus comprising:
- an elongate main frame;
- a plurality of cultivator sub-assemblies spaced along the length of said main frame, each of said sub-assemblies comprising a sub-assembly frame;
- a respective first linking means connecting each of said sub-assembly frames to said main frame for independent non-tilting floating movement of said sub-assembly frame with respect to said main frame in a first direction;
- and a respective second linking means connecting each of said sub-assembly frames to said main frame for independent non-tilting floating movement of said sub-assembly frame with respect to said main frame in a second direction transverse to said first direction;
- and wherein the first and second linking means for each of said sub-assemblies comprise a first pair of generally parallel link arms spaced from each other in said first direction and a second pair of link arms spaced from each other in said first direction and spaced from said first pair in said second direction, first joint means connecting one end of each of said link arms to said main frame for relative universal movement, and second joint means connecting the other end of each of said link arms to said sub-assembly frame for relative universal movement.
