<p>The head has a tiller motor with a fixation plate (20) and a mounting structure (26) that includes an end part (29) and a mounting assembly (30). A hydraulic motor (32) is mounted in the assembly, and the motor and the part are shifted along a direction orthogonal to the plate. A set of pipes (50) is arranged in the thickness of the plate, and a set of channels (52) is arranged in the part to connect the motor to the pipes. Rims (42, 44) mount the tiller drums (22, 24), where each rim is connected to the end part. Bearings (46, 48) are mounted on external surfaces of the assembly and the part.</p> |
