| 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. | ||||||

| A cultivator apparatus attached to a draw bar hitched to a tractor and having a tool bar attached to the draw bar and movable therewith. A cultivating mechanism is attached to the tool bar and is movable between positions of engagement and disengagement with the ground when the tool bar is moved. A plurality of cultivating units comprise the cultivating mechanism and are independently movable about the tool bar. A lateral support mechanism is comprised of gauge wheels mounted intermediate the ends of each of the cultivating units. Each gauge wheel is laterally offset with respect to the cultivating unit to which it is attached. | ||||||

| A linkage support for the ground tools of a cultivator gang and embodying a gauge wheel supported tool carriage which is connected to the head bracket of a tractor-drawn tool bar using a four bar parallelogram linkage so that it may rise and fall in accordance with an undulatory ground surface without a change in attitude with no fore and aft rocking of the carriage which, otherwise, would cause unequal ground tool penetration. Lateral tool-supporting beams associated with the carriage are provided with facilities whereby the ground tools may be clamped thereto in appropriate positions of lateral adjustment, and the beams themselves are capable of lateral adjustment to accommodate either right or left side installation of the ground tools. Additional facilities are provided whereby the gauge wheel supporting member may be clamped in varying positions of vertical adjustment to collectively vary the extent of ground tool penetration.
