Introduction
Cub Cadet 109 Garden Tractor
The Cub Cadet 109 is a garden tractor manufactured by Cub Cadet, a division of International Harvester, in Louisville, Kentucky. Produced between 1971 and 1974, this model was designed for residential lawn care and light utility tasks, serving as a reliable entry in the manufacturer's lineup during that period.
Engine and Performance
The tractor is powered by a 23.9 cubic inch (391 cc) air-cooled engine, producing 10 horsepower (7.5 kW) at a rated speed of 3600 RPM. It utilizes a dry cartridge air cleaner for intake filtration and requires an oil capacity of 1.5 quarts (1.4 liters), with maintenance intervals recommended every 30 hours of operation.
Transmission and Drivetrain
The machine features a hydrostatic transmission, allowing for infinite forward and reverse speed control without the need for manual gear shifting. It is a two-wheel-drive platform equipped with manual steering and mechanical disc brakes to ensure operational control. The system uses IH Hy-Tran oil for the transmission, with a total capacity of 7 quarts (6.6 liters).
Electrical and PTO Systems
The electrical system operates on 12 volts, supported by a Delco-Remy generator capable of 15 charging amps. For implement operation, the tractor is equipped with an independent front power take-off (PTO) engaged via a mechanical clutch. The engine ignition uses a Champion H-10 spark plug with a gap of 0.025 inches (0.635 mm).
Dimensions and Chassis
With a wheelbase of 44 inches (111 cm) and a ground clearance of 6 inches (15 cm), the 109 offers a stable footprint for garden work. It is equipped with 4.80/4.00-8 front tires and 6-12 rear tires, both designed for lawn and turf applications. The tractor supports mower decks in 38, 44, and 50-inch configurations, and offers an optional sleeve hitch for additional implements.
Conclusion
The Cub Cadet 109 is characterized by its simple mechanical design and hydrostatic operation, making it suitable for owners seeking a durable, vintage machine for lawn maintenance and light towing duties.
