The Avery Machinery Company was another veteran of the agricultural business that started in 1874. Avery built steam tractors for 18 years before producing its first gas tractor in 1909.The 14-28 has two forward speeds and a single reverse. To 'shift' from forward to reverse, the entire engine is slid on the frame. It is powered by a four-cylinder horizontally opposed kerosene engine. This tractor has an old restoration with rubber bolted to the wheels. #classic #averytractor #tractor #classictr
