1. An angle dozer assembly for a tractor including a C-frame having a pair of laterally spaced generally parallel arms located on opposite sides of the tractor, each of said arms having an elongated guide rail fixed thereto and located along the longitudinal axis of said arm, a moldboard haVing the rear portion thereof connected to a forward central point of said Cframe for adjustable movement about a vertical axis, a thrust member extending rearwardly from each lower corner of the moldboard, a carriage mounted on each arm for connecting the rear of each thrust member to the C-frame, said carriage comprising a base member carried by the associated arm for movement along said guide rail, each of said arms having at least three axially spaced and longitudinally aligned apertures formed therein and serving as stations for locating the moldboard in an angled-left position, a straight-across position, and an angled-right position, a manually removable pin carried by said base member and adapted to be located in one of said spaced apertures for locking the thrust member in one of said positions on said Cframe, and a pin retainer device rotatably carried by said base member and having a portion normally located in the path of movement of said pin for maintaining the latter in the accommodating aperture during a dozing operation.
2. The angle dozer assembly of claim 1 wherein said pin retainer device comprises a lever supported by a pivotal connection on said base member and said portion is a part of said lever having an inclined surface engageable by said pin when the latter is inserted into the carriage.
3. The angle dozer assembly of claim 2 wherein said pivotal connection is so located on the lever that said portion is movable due to gravitational forces into the path of movement of said pin after the latter is fully inserted into the carriage.
4. An angle dozer assembly for a tractor including a C-frame having a pair of laterally spaced generally parallel arms located on opposite sides of the tractor, each of said arms having an upper surface and a lower surface rigidly formed with an elongated guide rail located along the longitudinal axis of said arm, a moldboard having the rear portion thereof connected by a universal joint to a forward central point of said C-frame so as to provide adjustable movement of the moldboard about a vertical axis, a thrust member extending rearwardly from each lower corner of the moldboard, a carriage mounted on each arm for connecting the rear of each thrust member to the C-frame, said carriage comprising a generally U-shaped base member carried by the associated arm for movement along said guide rails, each of said arms having at least three vertically orientated and axially spaced apertures formed therein along the longitudinal axis thereof and serving as stations for locating the moldboard in an angled-left position, a straight-across position, and an angled-right position, and a manually removable pin carried by said base member and adapted to be located in one of said spaced apertures for locking the thrust member in one of said positions on said C-frame, and a lever pivotally carried by said base member and having a portion normally located above said pin for maintaining the latter in the accommodating aperture during a dozing operation.
