1. An earth-moving attachment for a vehicle comprising:
- a main frame assembly which includes a main frame-to-vehicle attaching means adapted to be mounted on the vehicle, a main beam connected at one end thereof to said main frame-to-vehicle attaching means and extending outwardly therefrom to have the longitudinal centerline thereof aligned with the direction of movement of the vehicle along a path;
a pair of earth-moving blade assemblies which can be movably mounted on said main beam, each earth-moving blade assembly includinga blade for moving earth in a predetermined direction with respect to the path,an inner edge on said blade locatable adjacent to said main beam,an outer edge on said blade,a first blade-to-main beam attaching means attaching said blade to said main beam,a second blade-to-main frame attaching means attaching said blade to said main beam,said first blade-to-main beam attaching means including means for adjusting the height of said blade above the path and means for adjusting the position of the inner edge of said blade with respect to said main beam longitudinal centerline, andsaid second blade-to-main beam attaching means including means for adjusting the position of the outer edge of said blade with respect to said main beam longitudinal centerline.

Abstract
An earth-moving attachment for use with a vehicle includes a pair of earth-moving blade assemblies mounted on a main beam. The earth-moving blade assemblies are adapted to be independently movable in several planes with respect to each other and with respect to the main beam so that a plurality of earth-working operations can be performed, and the attachment is amenable for use in conjunction with a wide variety of terrains. The blade assemblies are mounted and designed to efficiently transfer forces with the main beam.

22. In combination:
-
a vehicle adapted to move along a predetermined path; a main frame assembly which includes a main frame-to-vehicle attaching means adapted to be mounted on one end of said vehicle, and a main beam connected at one end thereof to said main frame-to-vehicle attaching means and oriented to have the longitudinal centerline thereof aligned with the predetermined path; a pair of earth-moving blades which can be movably mounted on said main beam, each of said earth-moving blades having an inner edge and an outer edge and each of said earth-moving blades being adapted to move earth in a predetermined direction with respect to said path; blade-to-main beam connecting means attaching said blade inner and said blade outer edges to said main beam in a manner such that said blades and said main beam form a closed polygon with each of said blades extending along one side of said polygon and said main beam extending along a diagonal of said polygon; and said blade-to-main beam attaching means including a blade position adjustment means associated with each blade for varying the orientation of each blade in at least two planes with respect to said main beam, each of said blade position adjustment means being adapted to vary the orientation of the blade associated therewith separately and independently of the other blade whereby the orientation of each blade with respect to the path can be varied in a plurality of planes. - View Dependent Claims (23, 24, 25, 26, 27)
