Comparison of new and traditional plows, United States, 1945
Photograph. Two men operating new (left) and traditional plows in a field. Official Caption: "Rome, 6/9/45--New plow makes debut---Pacing [sic] a tractor-drawn plow for comparison, the rototiller (at left) made its debut recently, thus entering formally the list of earth mixers lining up for postwar use by U.S. farmers. Graham-Paige Motors, which intend to produce the unit in volume, not only recommend it to farmers and nurserymen but are trying to arouse the interest of construction men as well. Designed to plow, disk and harrow in one operation, the machine has demonstrated its ability to mix cement with earth. The mixture, after being moistened and rolled, results in "soil cement" suitable for roads and landing fields. The mixing mechanism consists of sharp tines which revolve paddle-wheel fashion, claw the soil and produce traction. The rock problem has been solved by mounting the tines on coil springs which compress when they strike a barrier, and then roll it over.--FF Photo--Serviced by Rome OWI (A List out).
