A series of field tests of a 4-passenger snow vehicle are described. The machine is supported in the rear by 2 pontoons equipped with endless open-link tracks. Support in front is provided by 2 connected hickory skies. Small pneumatic tires lift the skis from bare ground when required. The front skis are attached to a steering yoke that will rotate over about 30 degrees from the horizontal so that the skis maintain a flat position on the snow. The skis have a 1 inch keel down the center to prevent side slip and aid in steering. A 6-cylinder automobile engine with transmission operates the vehicle at up to top speed of 2 miles per hour. Twelve characteristics to be noted in the performance of over-snow vehicles are listed. This vehicle mentioned met the requirements for performance. (Tucker SnoCat)In discussion R.W. Childreth describes a trial run of an over-snow vehicle developed by the Iron Fireman Manufacturing Company of Portland, Oregon. The trials were made on Mount Hood, in snow conditions difficult for ski travel. Operation details are given.
