Abstract: A suspension system for a work vehicle including a first cylinder having a piston side, a second cylinder having a piston side, a first proportional valve having a first position allowing flow between one or more accumulators, the piston side of the first cylinder, and the piston side of the second cylinder, and a second position preventing flow between the one or more accumulators, the piston side of the first cylinder, and the piston side of the second cylinder, and a second proportional valve having a first position allowing flow between a first accumulator and the piston side of the first cylinder and allowing flow between a second accumulator and the piston side of the second cylinder, and a second position preventing flow between the first accumulator and the piston side of the first cylinder and preventing flow between the second accumulator and the piston side of the second cylinder.

Abstract: An articulated work vehicle includes a front portion including a front set track assemblies, a rear portion including a rear set track assemblies, a power source installed in the front portion, a transmission installed in the front portion, a use mode, and a service mode. In the used mode, the rear portion is pivotally connected to the front portion and the transmission is operably connected to the power source, the front set of track assemblies, and the rear set of track assemblies. In the service mode, the rear portion is disconnected from the front portion, the transmission is disconnected from the front set of track assemblies, the transmission is removed from the front portion, and the transmission remains pivotally connected to the rear portion.

Abstract: One or more techniques and/or systems are disclosed for a new coolant tank that may also provide a structural element to the frame of the engine compartment. The coolant tank is comprised of a rear wall that also makes up a portion of the firewall in the engine compartment. A structural coolant tank component is engaged with the rear wall to form the coolant reservoir. The coolant reservoir can provide support to attach structural elements of the vehicle, and can also allow for improved space efficiency in the engine compartment. Further, improved access to the filling port is provided, while continued operation and desired function is maintained even at extreme vehicle tilt.

Abstract: A track work vehicle includes a track system. The track system includes a drive wheel supported by an axle housing that drives a continuous ground-engaging track, a saddle assembly that guides the track about the drive wheel and an undercarriage frame that supports one or more idler wheels that guide the track along a ground surface. The track work vehicle includes a fender assembly that includes at least one fender coupled to the track system to overlap a portion of the track.

Abstract: A suspension system for controlling multiple degrees of freedom of a cab of a vehicle has mounting pads that support the cab with a spring assembly connected between the chassis and each mounting pad, allowing the cab to move with multiple degrees of freedom. A lateral rod connects with one of the mounting pads, with the chassis, and restricts sideways motion of the cab. A longitudinal rod connects with one of the mounting pads, with the chassis, and restricts forward motion of the cab. A stabilizer bar connects with one of the front mounting pads, one of the rear mounting pads, the chassis structure, and controls forward pitch rate of the cab. A roll control bar connects with the rear mounting pads and the chassis structure, and controls lateral roll rate of the cab.
