ABSTRACT:
A plough for working between rows in a plantation comprises a chassis with pivotally-mounted, laterally-movable members having arms to carry earth-working tools. Movably connected to the chassis are curved sensors to contact the plants in two rows between which the plough is operating. There is a guide device for automatically centering the plough between the two rows, and there is a control including double-acting hydraulic rams for shifting the laterally-movable members to suit the width between the rows.
