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
