ABSTRACT:
An implement has a forward structure that supports a fluid distribution system including soil penetrating tools, such as hoe bodies of freely rotatable tine groups through which fluid is ditributed across a broad path. The supporting structure is connectable to a three point tractor hitch and linked to a cultivator frame by a forward parallelogram linkage. The cultivator frame supports a row of driven soilworking rotors and to the rear of the rotors, a wheeled seeder device is mounted on a parallelogram structure so that it can move vertically independently of the supportng structure or cultivator frame. A further, rear parallelogram structure interconnects the rear of the first mentioned parallelogram structure to supporting ground wheels and a hydraulic cylinder is positioned above the rear structure to lift the seeder for transport. A stop is associated with the parallelogram structures to limit their relative movements.
