Allis-Chalmers priced their B-Series tractors very competitively. The prices were usually slightly higher than the equivalent Simplicity, due to the chrome, nicer seat, etc. In addition to the novelty of these old price sheets, it is quite valuable to know the relative cost of different options, implements, etc. This helps you understand why some
items are rarer than others -- for example, adding the front loader with the recommended dual rear wheels, weights, etc. could cost almost as much as the basic tractor.
These old price sheets also show that there is not a "clean" model year break, nor an easy way to tell when a tractor was sold (or made). The 1967 price list shows that dealers were able to order essentially three "generations" of these garden tractor tractors at the same time -- the Big Ten, the later B-10/B-12,
and the B-110/B-112.
Also check the competitive comparisons, listed by both price and features. You'll likely be surprised by how far ahead of the competition that Allis-Chalmers really was. They offered features that were "industry firsts" at very
