Abstract: A dozing blade assembly includes a dozing blade, and a cutter mounted to the dozing blade. The cutter includes a compound digging face extending between a proximal edge and a distal edge. The compound digging face has a steeply oriented center segment, and shallowly oriented outer segments, for balancing downward penetration with forward pushability during moving the dozing blade assembly through material of a substrate. Purpose-built mounting surfaces on the blade can be used to provide for the different orientations, using flat plates to form the cutter.

Abstract: A machine includes a frame and a coupler assembly suspended below the frame, the coupler assembly configured for sideshift movement and having an implement mounting element for engaging with a mating feature on an implement. An implement grabber mounted to the coupler assembly is configured to grab an implement and move the implement via sideshift movement of the coupler assembly from a position lateral of the frame to a mounting position at which the mounting element of the coupler assembly can engage with the mating feature of the implement. A method of implement positioning for a machine includes grabbing the implement with a implement grabber mounted on a coupler assembly and moving the implement with the coupler assembly. The method also includes disengaging the implement from the implement grabber and actuating a mounting element of the coupler assembly to engage or disengage with the mating feature of the implement.

Abstract: A machine is provided having an engine system wherein at least one engine system component with an acoustic reflective surface is surrounded by a jacket configured to absorb sound from at least one sound producing device of the engine system. The jacket includes a sound absorbing material such as fibrous thermal insulation and an acoustic permeable covering between the acoustic reflective surface and the engine compartment of the machine. The acoustic permeable covering of the jacket may comprise a micro-perforated skin, whereby acoustic energy from the at least one sound producing device of the engine system can enter a volume defined by the jacket wherein it is absorbed by the sound absorbing material. A method of operating an engine system includes dissipating engine sound within a jacket surrounding an engine system component, the jacket including an acoustic permeable covering and a sound absorbing material positioned within the covering.

Abstract: Mounting pin arrangements are useful for connecting a first and a second structure together. When the pin is inserted in a mounting structure the mounting pin arrangement needs to expand to seal the arrangement to prevent dust and dirt from entering the mounting arrangement. The subject mounting pin arrangement includes a sleeve assembly that has a plurality of sleeve segments and an elastomeric is positioned and connected to adjacent segments and includes an end cap on the end portion of the sleeve. The sleeve includes a tapered bore therethrough. A pair of inserts are positioned in the bore and include tapers that interact with the taper in the bore of the sleeve to expand the sleeve to seal the mounting arrangement. The arrangement of components provides an expandable pin arrangement that will prevent dust or dirt from entering the mounting arrangement to prolong the life of the various components.
