发明名称 Cultivator
摘要 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.
