Introduction
Bush Hog HD-12 Garden Tractor
The Bush Hog HD-12 is a garden tractor produced between 1967 and 1968 in Galesburg, Kansas, USA. Designed for residential lawn care and grounds maintenance, this machine is part of the broader Bush Hog tractor lineup, focusing on durability and operational simplicity.
Engine and Performance
The tractor is powered by a Tecumseh HH820 engine, a single-cylinder, horizontal-shaft unit with a displacement of 453 cc (27.66 ci). It generates 12 hp (8.9 kW), providing sufficient power for light agricultural tasks and mowing. The engine utilizes an electric starter powered by a 12-volt system with a negative ground.
Transmission and Drive
The HD-12 features a shaft-driven hydrostatic transmission, which allows for infinite forward and reverse speed control without the need for manual gear shifting. This system requires Type A ATF fluid, with a recommended oil change interval of 50 operating hours. The tractor is configured with a two-wheel-drive system and utilizes manual steering.
Power Take-Off and Equipment
For attachment operation, the tractor is equipped with an independent mid-mounted Power Take-Off (PTO). The engagement of the PTO and drivetrain is managed via a manual clutch system, giving the operator direct control over implement usage, such as the compatible 32-inch or 42-inch mower decks.
Dimensions and Chassis
The tractor sits on a 54-inch (137 cm) wheelbase with an overall length of 81 inches (205 cm) and a width of 41 inches (104 cm). It features an open operator station for accessibility. The front tread is 31 inches (78 cm), while the rear tread is adjustable between 33 and 38 inches (83-96 cm), riding on 4.80/4.00-8 front and 27x8.50-15 rear turf tires.
