<p>The agricultural tractor attachment supports a rotary drum (D) concrete mixer which can tip to either side of the front. An hydraulic or electric motor is used to rotate the drum. Post fittings (31) permit coupling to the three point hitch of a tractor, and three bolted connections secure the drum. A braced inverted 'T' shaped post (P) may be mounted on two parallel 'C' section members (1) which form the arm, the members being positioned to accept lift truck forks. The arm locates a turntable.</p> |
