  • Model B-12



    big on power...
    big on comfort...

    This powerful new version of the "jillion job" tractor is your best choice when the going is likely to get tough. Its big Briggs & Stratton engine, built to Allis-Chalmers specifications, will make you wonder how a single-cylinder engine can run so smoothly. Exclusive "Synchro-Balance" design has made it possible.

    You'll like the instant response of the dual spring governor over the entire speed range-from idle to full throttle. It enables the tractor to ease up to an overload, instantly pour on the power and hum through it without a shudder.

    You'll like the many comfort features of the B-12, too. The seat is well padded and bucket shaped to give you extra support that will be especially welcome on steep hillsides or rough terrain.

    Large 16-6.50 x 8" front tires and 23-8.50 x 12" rear tires . . .  add still further to riding comfort. They also provide excellent flotation and reduce compaction.

    You can own the B-12 with pride and confidence.  It's from the tractor people who make the big ones.
