1. The angle steel front support was replaced by a closed-bottom cast iron support from serial number 136662 through 166999.
2. Becuase of copper shortages, the cooling system was pressurized from serial number 148500 through 166999. The temperature gauge registered 230 degrees rather than 210.
3. At 149700, a reversible drawbar with one-piece support, eliminating the roller assembly was adopted.
4. During 1944, at serial number 155445, new brake shoes with shorter linings were adopted.
5. Hydraulic Power Lift was available from the start, and Hydraulic Powr-Trol became available in May 1945.
6. The seat, 9 holes through late 1941. From then until late 1944 7 holes. By 1945, and through part of 1946, there were 5 holes. By mid to late 1946, it was down to 3 holes and stayed that way through 1947 when the padded seats became available.

Hope this helps,
