The theoretical prediction that vibratory locomotion can be used to double the otherwise available drawbar pull of bulldozers was experimentally proved. This report documents the design and tests of a bolt on thrust doubling kit installed on an 11,000 lb bulldozer drawbar pulls as high as 20,600 lbs were measured. The kit is needed to upgrade the performance of the lightweight helicopter liftable bulldozers used by Marines at advanced bases. By adding only 10 to the weight of the tractor, its power output can be doubled. A detailed documentation of the tests are given along with an appendix containing all the required design theory. The report thus contains in one package all that is currently known concerning the use of vibratory locomotion for high traction development.
