Abstract: An articulated snow plow system for use with a vehicle includes a blade center section having a moldboard section and left and right plowblade sections which are wider than the blade center section. The plowblade sections each include a moldboard section and are mounted to the blade center section at opposite sides thereof and pivotable relative to the center blade section about a substantially vertical pivot axis, to swept forward and swept backward positions. The snowplow assembly includes a support frame, the blade center section being coupled to the support frame through an intermediate pivot assembly which permits a limited amount of float to allow the blade center section, and the plowblade sections pivoted thereto, to follow the contour of the ground.

Abstract: An articulated snow plow system for use with a vehicle comprising a mounting plowblade section having a moldboard section, at least two mounting sides, and at least one mounting structure located on each of the mounting sides; and a plurality of extending plowblade sections each having a moldboard section and an engagement mechanism capable of engaging the mounting structure located on each of the mounting sides; an extending plowblade section being pivotally coupled to each mounting structure at the engagement mechanism. The articulated snow plow system for use with a motorized vehicle comprising an articulated snow plow coupled to a reactive controlled pressure snow plow system for use with the articulated snow plow. The articulated snow plow having a mold board and the reactive controlled pressure snow-plow system including a reactive controlled pressure mechanism mechanically coupled to the vehicle and to the moldboard of the articulated snow plow.

Abstract: A portable farm type elevating auger is disclosed supported on a truck having lower hinged frames one of which is connected to adjacent the feed end of the auger and the other to a roller carriage which moves along a track longitudinally of the auger underside as a cable connected between the two frames is wound or unwound from the drum of an operating winch to change the hinge angle between the frames and thereby the inclination of the auger. Pivotally mounted on the carriage is a spring biased latch to which the cable is attached. The spring is biased to rotate the latch when the tension of the cable thereon is removed as by the cable or a sheave breaking so that the latch engages the next track hanger as the auger starts to fall and thereby prevents its total collapse.
