The Allis-Chalmers WC Tractor was manufactured between 1933 and 1948. The Allis-Chalmers WC Tractor first came out at a price of $1,341 (1947), but you might be one of the lucky ones who found a good deal lower than that. The bad news is that, like any other tractor, the Allis-Chalmers WC Tractor needs spare parts to keep it running; the good news is that we have all the parts you need at 60% off dealer prices in our inventory. Make sure you have access to your tractor serial number, because there is a chance that the Allis-Chalmers WC parts you need depend on that serial number. Usually, the serial number is printed on the differential housing. That serial number is determined by the year of manufacturing, so for a 1933 model, it starts with 1, for a 1934 model it starts with 29, for a 1935 model it starts with 3127, for a 1936 model it starts with 13870, for a 1937 model it starts with 31784, for a 1938 model it starts with 60790, for a 1939 model it starts with 75216, for a 1940 model it starts with 91534, for a 1941 model it starts with 103517, for a 1942 model it starts with 114534, for a 1943 model it starts with 123171, for a 1944 model it starts with 127642, for a 1945 model it starts with 134624, for a 1946 model it starts with 148091, for a 1947 model it starts with 152845, for a 1948 model it starts with 170174, for a final model it starts with 178202. They also have differential hand-operated mechanical drum brakes. The 3-point hitch is very reliable. It is also worth noting that the transmission rear PTO runs at 535 rpms.
