Photograph of the inside cab view of soil coring machine from drivers seat. Tube cleaner in foreground is near the operator where 99% of fastened cores in tip can be jared loose by hand simply by setting tube in the cleaner and pushing downward on soil coring tube. Lower limit switch can be used with power by swinging around drive head with soil coring tube being lowered. Cover for drive mechanism. Hole in floor board to dispose of soil from the coring tube (hinged to jeep cab) and held open by 1/4 inch stove bolt which hinges to the right or left in double nut welded to jeep cab. Heater located so that heat is thrown back into cab. The base of the soil coring machine shown here is 1/4 inch slab steel and is too light for this application, the steel springs downward when pulling soils from heavy clays.

The tubes one 52" long for making 4 ft. tests in alfalfa land for high water table-three short tubes, one for collecting profile of shallow soil under native vegetation, one for collecting a deep soil profile under virgin conditions (sample to be carried into the cultivated field for comparison and evaluate soil losses) and a third short tube to be used in process of surveying. Cab should have ample window space for light, the inside being painted with aluminum paint for better light reflection. Comfortable seats, both front and back should be installed. The front seat here is a recovered bucket seat from a '36 Plymouth Panel. Muffler is moved outward and attached to body.
