ABSTRACT:
A cultivating implement has an elongated frame portion with a front three point coupling that connects to the three point lift of a conventional tractor. A rear supporting structure for a further implement has spaced apart beams that extend forward to pivots near the lower two points of the front coupling. The structure has interconnected frame beams that are supported on ground wheels and the rear ends of the forwardly extending beams are fixed to vertical frame beams. Rearwardly extending arms are pivoted to the interconnected frame beams and these arms together with coupling plates on an upper tie beam, form a rear three point coupling. The arms are interconnected to the remainder of the structure by adjustable carrier arms. Ground wheels support the structure and a further implement that is connected to the rear coupling.
