Belt Rail Single Track B 1918
This tractor was built to compete with wheel tractors. The belt track allowed it to run on softer ground than wheel tractors. This one was bought in Merced, CA and is the only one in existence that we know of. This company was organized in 1917 and went out of business in 1920.

COD Wheel Tractor Model B 1919
The significance of the initials COD has been lost, but it was probably named for the three stockholders Conrad, Ogard & Daniel. Few of these tractors remain. Belt pulleys ran off the flywheel to operate the oil pump, fuel pump and water pump.

Avery 6 Cylinder Model C 1919
The Avery 6-cylinder tractor was a big success in practically every kind of farm work. The Avery was advertised as a high grade tractor at an attractive price, which included such accessories as a platform, seat, tool box, draw bar and an air cleaner, equipment that other small tractor makers charged extra for. Exhaust gases were piped to the rear drive gears to clean and lubricate them.
