A cable actuated dump trailer assembly includes a vehicle having a frame. A dump trailer is pivotally coupled to the frame. A first jack arm is pivotally coupled to the frame. The first jack arm abuts the dump trailer offset from a rear end of the dump trailer whereby the first jack arm exerts an upward force on the dump trailer pivoting the dump trailer into a dumping position. A winch is coupled to the frame. A first cable is coupled to the winch and the dump trailer. A first pulley is coupled to the first jack arm. A medial portion of the first cable engages the first pulley whereby the first cable urges the first jack arm towards an upright position as the first cable is wound onto the winch whereby the dump trailer is urged into the dumping position.
