ABSTRACT:
A particulate material spreader comprising a ground-contacting platform adapted for detachable connection to towing device which causes the platform to traverse the ground so as to engage at least in part the surface thereof subtended by the platform. Engagement is by one or more members supported by the platform transversely with respect to the transit path of the platform. Each member has at least one vertically resolvable surface irrespective of the attitude of the platform. The connection is such that a pre-set angle of the platform with respect to a horizontal plane is maintained during transit whereby the members gouge relatively high areas of engaged ground and fill relatively low areas thereof with spoil from those high areas. The platform is attached to the towing device by a selectively detachable three-point linkage which may be mounted on one end or the other of the platform.
