Curt --- Hayfarmer has given some good info on the JD 202H. It was a decent plow to use and a good design for its time. The 202H did have a few drawbacks. One, is it has quite a few moving parts, but this really wasn"t a problem if properly maintained. Another drawback was trash tended to build up around the standards if the plow was used in very heavy crop residue. The advantage the "tumble" or "roll over" plows had over the 202, was they did a better job of sheddind this build up of trash. This was obviously because these types of plows are turned upside down at the end of each pass in the field. The 202 design only raises and lowers at the end of each cycle. I"m not certain how many JD 202H plows were built, but production continued until the very early 1960s. All of the 202Hs I"ve seen were on rubber tires. The 202H was a popular plow in the western states and were used primarily on irrigated land. I didn't realize that John Deere produced the model 101. I know one was produced as a drawn two way 1 bottom plow in the 1930s and 40s, on steel. John Deere began production of the model 303H in 1959, which was one of the largest drawn two-way 3 bottom plows built at the time. It was closely designed to the 202H, but the 303H was more heavily constructed and was intended for deep plowing. In the 1960s, I pulled a 303H using a Caterpillar D4 7U for deeper plowing and was very satisfied with this implement.
