    摘要： A cultivator designed to dig up weeds from between rows of crop. The structure of the cultivator is unified with a laterally extended front bar that carries digging tines that dig up weeds along each side of the row of crop of a number of rows at one time. A rear bar is spaced from and in parallel relationship with the front bar and carries digging tines that dig up weeds down the center of the rows. The structure is mounted to a tractor, and depth controlling wheels, supported on the ground during operation, determine in part the depth of penetration of the tines into the ground.

    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.
