Introduction
Jacobsen Chief 800 Garden Tractor
The Jacobsen Chief 800 is a classic garden tractor produced between 1964 and 1969 in Racine, Wisconsin, USA. Designed for property maintenance and light agricultural tasks, this model is part of the Chief series, known for its mechanical simplicity and robust construction.
Engine and Performance
The tractor is powered by an air-cooled, single-cylinder Kohler K181 gasoline engine. It features a displacement of 305 cc (18.64 cubic inches) and provides a gross power output of 8 horsepower (6.0 kW) at a rated speed of 3600 RPM. The engine uses a dry-type air cleaner and relies on a 12-volt electric starter system.
Transmission and Drivetrain
The Chief 800 utilizes a belt-driven gear transmission, manufactured by Peerless. Two configurations were offered during its production run: a 3-speed transmission (available on early models) and a 4-speed transmission (introduced in 1966). Both versions include one reverse gear and are operated via a manual idler pulley clutch system. Power is delivered to the rear wheels in a two-wheel drive configuration.
Mechanical Specifications and Dimensions
Built with an open operator station, the tractor features manual steering and mechanical band brakes. Its compact design includes a 42-inch wheelbase and an overall width of 33 inches, providing high maneuverability in confined garden spaces. The ground clearance under the frame is 11.75 inches, while the front axle clearance measures 8.75 inches.
PTO and Equipment
The tractor is equipped with an independent mid-mounted Power Take-Off (PTO). This system is pulley-driven and controlled by a manual clutch, allowing the operator to engage or disengage the mower deck as needed. The unit is designed to accommodate 36-inch or 42-inch mower decks.
Conclusion
The Jacobsen Chief 800 remains a notable example of mid-1960s garden tractor engineering. Its straightforward mechanical design, combined with the reliable Kohler engine and flexible transmission options, makes it a functional choice for enthusiasts focused on property maintenance and vintage equipment restoration.
