A hitch for connecting a first implement to a second implement pulled behind a tractor is disclosed which has a first parallel linkage assembly with two upright members with upper and lower portions, the upper portions of the upright members being connected by an upper follower arm and the lower portions of the upright members being pivotally connected by a lower follower arm. One upright member is adapted to rigidly connect to the second implement. A central horizontal member has two opposed ends and front and rear sides. An upright member of the first parallel linkage is rigidly connected to the front side of the horizontal member. Ground engaging caster wheels are pivotally mounted on each end of the horizontal member. A second parallel linkage has two upright members with upper and lower portions. The upper portions of the upright members are pivotally connected by an upper lifting arm and the lower portions of the upright members are pivotally connected by a lower lifting arm. One upright member is rigidly connected to the rear side of the horizontal member and the other upright member is adapted to connect to the first implement. An actuator is mounted between the central member and the second parallel linkage and adapted to move a connected first implement between a first lowered, ground-engaging position and an elevated position, wherein the weight of the first implement is substantially carried by the caster wheel. The hitch may be employed for connecting a harrow or drag behind a tractor-pulled disc tiller.
