    B-10/B-12 LAWN



    [Source:  Brochure, Allis-Chalmers B-10/B-12 Lawn and Garden Tractors, OPE-1000, Oct 1966 ]

    Browse the October, 1966 AC catalog, introducing the new B-12,  and including the again re-named B-10.   Note that the original B-10 actually had a 9 HP engine.  When the HP was increased to 10 in 1965, it was renamed the Big Ten.  However, when the B-12 was introduced in 1966, the Big Ten was renamed once more to the B-10.

    This customer brochure information has been expanded by adding dealer product information, as noted by this different color.  This new dealer sales information adds valuable detail, and has helped answer a lot of questions in the evolution of these tractors.  In addition to the engines, these "late" models have these differences:

    • The Bumblebee logo was first used, and quickly identifies these "late" B-10s from the early ones.  All B-12s have the bumblebee . . .
    • Model ID plates were first used in the grille, in addition to the AC logo plates.
    • The engine and drivetrain are now painted black, instead of yellow.  
    • The backrest on the B-10 is now taller, while the B-12 uses a totally new, different seat.
    • B-12 also uses a new black steering wheel, while the B-10 steering wheel remains white.  Both have a chrome center cap with the Allis-Chalmers trademark.
    • A quicker (5.1 to 1) steering ratio is now used.New, heavier front axle and spindles, and wider front wheels with 6:50 x 8 tires on the B-12.

    Also note that some of the "drill-down" information on the specifications pages is from still other sources.  This is done to provide more comprehensive content.
