A self-propelled off-road agricultural vehicle is provided with a hydraulic propel circuit protection system. The hydraulic propel circuit protection system reduces extreme pressure buildup from the motors when the pumps and/or motors are rapidly deactivated. The hydraulic propel circuit protection system may include a propel manifold with integral valving and an accumulator to protect a propel circuit of the self-propelled off-road agricultural vehicle. External relief valves which may be integrated into the propel manifold may limit the high pressure condition on the outlet of the motors to a level that prevents damage to the hydraulic motors and the accumulator provides supplemental flow and thus prevents the extremely low pressure condition from occurring at either side of the motors.
