Allis Chalmers B Tractor Parts

Allis-Chalmers B Tractor Parts

Allis-Chalmers designed the Model B for smaller farms that needed an affordable, useful tractor without the size of a full-scale machine. Introduced in 1937, the B was light and narrow, with an arched front axle and high clearance that made it useful around one-row crops, truck farms, and nurseries.

The Model B was also notable for being sold with pneumatic tires rather than an optional steel-wheel setup. Production continued through 1957.

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, between the carburetor and fuel filter.

The table below uses one beginning tractor serial number for each Model B year:
