If the conservationist had to depend upon enough horses to equal the horsepower of this tractor for pulling heavy instruments, cutting furrows and leveling dunes, his feed bill alone would be tremendous. But this mechanical hitch does the work very nicely on this project near Dalhart, Texas, April 18, 1937. Furrows are cut, and the wind is expected to undo some of its damage by blowing top soil from the dunes back across the fields. (Photo by AP Photo)
