Description: Special Report
Summary: Instrumentation, techniques, and results of tests carried out with modified weasels in Central Greenland during the summer of 1955 are given. Maximum drawbar pull was measured together with meteorological conditions and conditions of the snow cover, including snow temperature, density, and depth of distortion due to to the vehicle tracks. With this vehicle, the depth to which snow properties determine maximum drawbar pull may vary from 15-30 cm. No correlation was found in the case of ram hardness numbers. Maximum drawbar pull of the weasel cargo carrier varied from 2800-3700 lb., and 75 percent of the tests saw values in the range from 3000-3400 lb. Recommendations for future test programs are given.
