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.

Apparatus and method of removing a transmission from an articulated work vehicle

Techniques and/or systems are disclosed for an implement attachment assembly for a work vehicle. The implement attachment assembly includes a member having a body extending longitudinally between a first end and a second end. The first end includes a central axis disposed at a first height relative to a member vertical axis and the second end includes a central axis disposed at a second height relative to the member vertical axis. The first end central axis is operably disposed at a different height than the second end central axis. The first end is configured to operably connect to the work vehicle. The second end is configured to operably connect to a coupling device.

Implement attachment assembly and method of use

A suspension system for an operator station of a work vehicle having a chassis includes a subframe structure, a plurality of mounting pads, a plurality of shock absorbers, a rear lateral rod, a front stabilizer, and a pitch control stabilizer. The plurality of mounting pads is positioned on a top surface of the subframe structure. The plurality of shock absorbers connects between the chassis and the subframe structure near each of the mounting pads. The rear lateral rod connects to the rear side of the subframe structure and to the chassis. The front stabilizer connects to the front side of the subframe structure and to the chassis. The pitch control stabilizer connects to the right side of the subframe structure and to the chassis.

Suspension system for an operator station of a work vehicle

An axle suspension supports an axle housing on a vehicle frame. The suspension includes left and right pivot rods attached to left and right frame members. A suspension arm has a first end fixed to a rear end of the axle housing and has a second end pivotally coupled to the left and right pivot rods. A variable length left hydraulic cylinder has an upper end pivotally coupled to the left frame member and has a lower end pivotally coupled to a front end of the axle housing. A variable length right hydraulic cylinder has an upper end pivotally coupled to the right frame member and has a lower end pivotally coupled to the front end of the axle housing. The left and right hydraulic cylinders are hydraulically connected in parallel.

Axle suspension

A charge pressure reduction circuit for a loader backhoe in which a directional control valve causes the charge pump to operate at a system pressure high enough to adequately supply a clutch circuit when conditions indicate the vehicle is operating in a loader or transport mode. The directional control valve causes the charge pump to operate at a lower pressure as, for example, required for a lubrication circuit when conditions indicate the vehicle is in a backhoe operating mode.
