• a pair of hangers, each hanger of said pair of hangers having an upper end being coupled to said tandem axle trailer, each hanger of said pair of hangers extending downwardly from said tandem axle trailer, each hanger of said pair of hangers having a lower end, each hanger of said pair of hangers having a pivot point being aligned with said lower end, said first outward section of said second axle extending through said pivot point of a respective one of said pair of hangers, said second outward section of said second axle extending through said pivot point of a respective one of said pair of hangers, said second axle rotating about said lengthwise axis of said first outward section and said lengthwise axis of said second outward section when said second axle is moved between said lowered position and said lifted position;
• a pair of second wheels, each second wheel of said pair of second wheels being rotatably disposed on said second axle wherein each second wheel of said pair of second wheels is configured to roll along the support surface when said second axle is in said lowered position, each second wheel of said pair of second wheels being lifted upwardly with respect to said pair of first wheels when said second axle is in said lifted position wherein each second wheel of said pair of second wheels is configured to be lifted from the support surface such that a user can steer said tandem axle trailer on said pair of first wheels, each second wheel of said pair of second wheels having a hub, said hub of each second wheel of said pair of second wheels being rotatably coupled to a respective one of said first end and said second end of said second axle;
• a drive box being mounted to said tandem axle trailer, said drive box having a pair of inputs and an output, each input of said pair of inputs being in mechanical communication with said output, said output being rotated when either of said pair of inputs is rotated, each input of said pair of inputs having a rotational axis being oriented perpendicular to a rotational axis of said output, said drive box having a first lateral side and a second lateral side and a back side, each input of said pair of inputs being located on a respective one of said first lateral side and said second lateral side, said output being located on said back side;
• a sleeve being coupled to said output of said drive box, said sleeve being rotated when said output rotates, said sleeve having a coupled end being coupled to said output of said drive box, said sleeve having a free end being open into an interior of said sleeve, said sleeve having an inside surface, said inside surface being threaded, said sleeve being rotated about an axis extending between said coupled end and said free end when said output rotates;
• a screw being threadably coupled to said sleeve, said screw being coupled to said second axle, said screw being extended outwardly from said sleeve when said sleeve is rotated in a first direction, said second axle being urged into said lowered position when said sleeve is rotated in said first direction, said screw being retracted into said sleeve when said sleeve is rotated in a second direction, said second axle being urged into said lifted position when said sleeve is rotated in said second direction, said screw having an outer surface, said outer surface being threaded, said screw extending into said free end of said sleeve, said outer surface threadably engaging said inside surface of said sleeve, said screw having a distal end with respect to said free end of said sleeve;
• an annular coupler extending around said medial section of said second axle, said annular coupler having an outside surface, said distal end of said screw being coupled to said outside surface, said medial section of said second axle being urged toward said sleeve when said screw is retracted into said sleeve, said medial section of said second axle being urged away from said sleeve when said screw is extended from said sleeve;
• and
• a crank being releasably mateable to a respective one of said pair of inputs of said drive box wherein said crank is configured to be rotated by the user, said sleeve being rotated in said first direction when said crank is rotated in a primary direction, said second axle being urged into said lowered position when said crank is rotated in said primary direction, said sleeve being rotated in said second direction when said crank is rotated in a secondary direction, said second axle being urged into said lifted position when said crank is rotated in said secondary direction, said crank including a coupling portion being perpendicular to a middle portion, said crank including a handle being rotatably coupled to said middle portion wherein said handle is configured to be gripped by the user, said handle extending in an opposite direction from said middle portion with respect to said coupling portion wherein said handle is configured to extend away from said drive box toward the user when the user is standing next to said drive box, said coupling portion being releasably mateable to said respective input of said drive box.
