Introduction
Avery Ro-Trak Row-Crop Tractor (1938–1941)
The Avery Ro-Trak is a row-crop tractor manufactured in Peoria, Illinois, between 1938 and 1941. It is recognized for its mechanical versatility and its ability to adapt its wheel configuration to specific agricultural requirements.
Engine and Powertrain
The tractor is powered by a liquid-cooled, 6-cylinder Hercules QXB-5 gasoline engine with a displacement of 205 cubic inches (3.4 liters). The fuel system utilizes a Zenith carburetor, and the intake air is filtered via an oil bath air cleaner. The engine operates at a rated speed of 2,000 RPM. Power is transmitted through a mechanical dry disc clutch and a gear-based transmission system providing three forward speeds and one reverse speed.
Chassis and Wheel Configuration
The Ro-Trak features a two-wheel drive system with manual steering and an open operator station. A distinctive technical feature is the front wheel assembly mounted on swing-arms. This design allows the operator to adjust the front tread width from 16 to 56 inches, enabling a tricycle configuration for specialized row-crop work or a standard-tread configuration. Avery noted that this adjustment could be performed by one person using a jack and two wrenches in approximately 30 minutes.
Agricultural Capabilities
Designed for field operations, the tractor is rated for use with 2-3 bottom 14-inch plows. The rear tread width is adjustable between 56 and 84 inches, providing stability and flexibility when working across varying row widths and terrain conditions.
Conclusion
The Avery Ro-Trak represents a period of mechanical innovation in American tractor design, specifically regarding field adaptability. Its combination of a 6-cylinder engine and adjustable chassis geometry made it a functional tool for mid-20th-century row-crop farming.
