Abstract

See full text

A ditch forming implement, for use with a working vehicle, has a frame for towing connection to the working vehicle and which supports a rotatable impeller member thereon for spreading soil in a laterally outward direction relative to a forward path of the implement. A driven pulley wheel is fixed to a rear of the impeller member for rotation together relative to the frame. A drive shaft assembly operatively transfers rotational drive from a power take-off of the working vehicle to a driven pulley wheel on the frame, to be subsequently transferred to the driven pulley wheel by a drive belt connected between the driven and drive pulley wheels.
