An adjustable bow lift apparatus for extending the overall height between the bed and bow cover on a cotton module truck during loading or unloading a cotton module, generally including a set of metal tubular frames, one for the top of each side wall, and pivotally attached a first distance from the further most end of each side wall. A set of actuators for each side of the frame for lifting and lowering the bow lift apparatus, each actuator is attached to the last side wall frame member of the truck, with the actuator extension arms pivotally attached at the lower frame on each side of the bow lift apparatus. A plurality of on board power devices may be adapted for rasing and lowering the adjustable bow lift apparatus during loading or unloading a cotton module, such as air, hydraulics or electrical. A first and second modified bow providing level in-line support of the canvas top on a module truck, attached a first and second distance from the further most end of the bow lift apparatus frame, and extending the width of the module truck bed, and attached to the opposing frame member. A set of guide arms attached to the lower frame of the bow lift apparatus, a first, second and third distance from further most end of the apparatus, and extending downward, on the outside of the module truck side walls, of a distance in length to ensure guidance and stability of the adjustable bow lift apparatus during raising and lowering of the apparatus.
