The invention discloses an adjustable hitch for towing an air cart behind a cultivator or similar tillage device. The invention consists of a pivotable hitch which is connected to a pair of cultivator pivot arms pivotally mounted on the cultivator frame. The pivot arms are controlled by a pair of hydraulic cylinders. At the air cart end, the hitch has a pair of slides which are inserted into a pair of slots located on an offset air cart hitch. When the hydraulic cylinders move the cultivator pivot arms, the hitch pivots and allows the slides to move within the slots of the offset air cart hitch. The invention also has a pair of spring-biased, hydraulically actuated latches for securing the hitch in either the field or transport mode.
