Allis Chalmers CA Tractor Parts

The Model CA followed the Model C in 1950 and gave small farms a little more speed and flexibility. It kept the compact row-crop layout and four-cylinder engine, but added a four-speed transmission and a live PTO operated by a hand clutch. That hand clutch lets the PTO keep turning while the tractor is stopped, which is useful with a mower or other PTO-driven equipment.

Built at West Allis from 1950 through 1958, the CA remained a practical tractor for cultivation, mowing, and general farm work. The model is a useful step between the older C and the newer D Series.

Serial number locations: The tractor serial number is stamped on top of the transmission case, next to the shift lever. The engine serial number is on the rear left-hand side of the engine.

The table below shows the beginning tractor serial number for each Model CA year:

1953-1955

1953 22,181
1954 31,424

1956-1958

Model CA year Beginning serial number
1956 37,203
1957 38,618
1958 38,977

Total production: 39,499 Model CA tractors.

The final CA serial number was 39,513.
