Abstract: A working vehicle has a ballast weight system including a fulcrum mounted on the vehicle frame and a ballast weight configured to pivot between a mounting configuration with the ballast weight is resting on the ground and an operational configuration with the ballast weight is carried by the vehicle frame. The ballast weight has a mounting arm and a lower corner portion. The mounting arm has a recess configured to interact with the fulcrum, wherein in the mounting configuration, the recess faces sideways such that the work vehicle is driven towards the ballast weight until the fulcrum interfaces with the recess. A catch mechanism secures the ballast weight to the fulcrum. A lift mechanism attaches between the ballast weight and the vehicle frame such that the lift mechanism pushes on the corner portion to pivot the ballast weight about the fulcrum. A latch mechanism pins the ballast weight in the operational position.
