A hydraulic system for a work vehicle that has a frame, a ground-engaging implement that moves the frame over a ground surface, and an attachment connected to the frame for movement with respect to the frame. The hydraulic system includes a pump that pumps hydraulic fluid, a first conduit fluidly connecting the pump and the attachment, a reservoir that contains hydraulic fluid, a second conduit fluidly connecting the pump to the reservoir, a fluid resistor fluidly connected with the second conduit, and a valve. The fluid resistor dissipates power from the work vehicle. The valve actuates between a first state in which the valve fluidly connects the pump to the first conduit such that hydraulic fluid is directed to the attachment, and a second state in which the valve fluidly connects the pump to the second conduit such that fluid is directed through the fluid resistor and into the reservoir.

In accordance with an example embodiment, a structural attachment assembly for a work vehicle is disclosed. The structural attachment assembly comprises opposing first and second connector ends. The first connector end is arranged for removable or fixed coupling to a frame of the work vehicle and the second connector end is arranged for removable or fixed coupling to another member of the attachment assembly. A support structure is coupled to and interposedly arranged between the first connector end and the second connector end. The support structure comprises a plurality of walls with inner surfaces defining an interior cavity. The interior cavity comprises a first reinforcement member and a second reinforcement member relatively arranged to form a structural reinforcement member that extends substantially through a length of the interior cavity.
