DIFFERENCES BETWEEN MODELS
The major equipment and functional difference between the U.S. Army and U.S.M.C. models is the addition of a front
cable guide (1) and Y-bar straps (2). This cable guide (1) and Y-bar assembly (2) enable the U.S.M.C. MK48/16 to use its
single winch to load and unload disabled payloads. The U.S.M.C. model can be utilized by other two-winch towing
tractors, but the single-winch tractors are limited to winching operations to this model only. The serial numbers of
semitrailers for single winch operation are (558647) thru (558668). The U.S.M.C. models are also equipped with a 40-foot
positive jumper cable on the APU jump start system. The Army model positive cable is 28 feet long.
