Abstract: A diesel exhaust fluid (DEF) tank for an off-road vehicle including a retaining bar configured to support the DEF tank and a channel molded into a side of the DEF tank. The channel is configured to interface with the retaining rod. The DEF tank further including a cutout formed within the channel, wherein the cutout establishes a gap between the retaining bar and a body of the DEF tank. The DEF tank also includes a drain channel molded into an exterior surface of the DEF tank. The drain channel is configured to provide structural support to the DEF tank, and the gap is configured to enable DEF flow downwardly into the drain channel without contacting the retaining bar.

Abstract: A system includes a mounting assembly for a muffler of an off-road vehicle including a first mounting pad rotatably coupled to a first support. The first mounting pad is configured to rotate in a first direction and in a second direction, opposite the first direction, about a first rotation axis. The mounting assembly also includes a second mounting pad rotatably coupled to a second support. The second mounting pad is configured to rotate in the first direction and in the second direction about a second rotation axis. Moreover, the first and second mounting pads are laterally offset from one another relative to a longitudinal axis of the muffler, the first and second mounting pads are configured to support the muffler, and the first and second mounting pads are configured to independently rotate relative to the respective supports about the respective rotation axes.

Abstract: A system includes a muffler coupled to a frame of the off-road vehicle and mounted in a substantially horizontal orientation and a diesel oxidation catalyst (DOC) fluidly and mechanically coupled to the muffler. In certain embodiments, the DOC is mounted in a substantially vertical orientation rearward of the muffler relative to a primary direction of travel of the off-road vehicle.

Abstract: A diesel exhaust fluid (DEF) tank for an off-road vehicle including a first conduit channel molded into an exterior surface of the DEF tank, at a first depth, in which the first conduit channel is configured to guide a first conduit along the exterior surface of the DEF tank. The DEF tank further including a second conduit channel molded into the exterior surface of the DEF tank at a second depth, different than the first depth, in which the second conduit channel is configured to guide a second conduit, and the first depth and the second depth are selected to create a vertical gap between the first conduit and the second conduit at an intersection of the conduits.

Abstract: A horizontal muffler for an agricultural vehicle is provided. One agricultural vehicle includes an exhaust system having a muffler configured to direct exhaust out of an engine and to reduce a noise of the exhaust. The agricultural vehicle also includes a steering wheel configured to control steering of the agricultural vehicle. The muffler is disposed forward of the steering wheel relative to a direction of travel of the agricultural vehicle. Moreover, the muffler extends in a substantially horizontal direction such that a flow of the exhaust through the muffler is substantially parallel to a ground surface.

Abstract: A suspension system for a cab of an off-road vehicle includes a superstructure configured to receive a cab frame. The superstructure forms a framework, the corners of which receive suspension assemblies and dampers. The suspension assemblies include one or more springs or resilient elements to resist suspension motion, and the dampers provide dampening of the motion. Lateral and longitudinal suspension motions are resisted by links between the corners of the superstructure. An anti-roll bar reduces roll. The entire suspension system may be pre-assembled and then joined to the vehicle chassis frame. The cab frame may then be placed on the suspension system. Parts of the suspension system may interface with and be housed by roll-over protective structures.
