Introduction
Allis-Chalmers G: Compact Tool Carrier Tractor
The Allis-Chalmers G is a specialized tool carrier tractor produced between 1948 and 1955. Designed primarily for small-scale farming and market gardening, it features a unique rear-mounted engine configuration that distinguishes it from conventional tractors of its era.
Engine and Powertrain
The tractor is powered by a 1.0-liter (62 cubic inch) 4-cylinder vertical L-head engine. It operates at a rated speed of 1800 RPM and utilizes a liquid-cooling system. The air intake is protected by an oil bath air cleaner. Power is delivered through a dry disc clutch, with a standard 3-speed gear transmission or an optional 4-speed creeper transmission, allowing for precise speed control during agricultural operations.
Mechanical Configuration
The Allis-Chalmers G utilizes a two-wheel drive system with manual steering for direct control. Braking is managed by mechanical external expanding brakes. The design allows for adjustable front and rear treads, ranging from 36 to 64 inches, providing flexibility for various row widths. It features an open operator station and was designed to accommodate a full line of custom implements mounted directly under the tractor's frame.
Electrical System
The electrical system is built on a 6-volt architecture. It includes a generator for charging the battery and a starter motor for engine ignition. The system is configured with a positive ground.
Conclusion
With 29,976 units produced, the Allis-Chalmers G serves as a specialized utility machine. Its design, emphasizing visibility and under-belly implement mounting, makes it particularly suited for precise cultivation and small-plot management tasks where high maneuverability is required.
