Introduction
John Deere 312 Garden Tractor
The John Deere 312 is a garden tractor manufactured between 1977 and 1978 in Horicon, Wisconsin, USA. Designed for residential landscaping and maintenance, this model represents a specialized segment of John Deere's compact machinery from the late 1970s.
Engine Specifications
The tractor is powered by a Kohler K301AQS single-cylinder, air-cooled gasoline engine. It features a displacement of 476 cc (29.1 ci) and provides a gross power output of 12 hp (8.9 kW). The engine utilizes a horizontal shaft configuration and a dry-type air cleaner, supported by a 12-volt electrical starting system.
Transmission and Drivetrain
Power is transferred via a shaft-driven Sundstrand 15 hydrostatic transmission. This system allows for infinite forward and reverse speed control without the need for traditional gear shifting, enhancing maneuverability during mowing or towing tasks. The tractor operates on a two-wheel drive system.
Dimensions and Chassis
The chassis features a 46-inch (116 cm) wheelbase with an overall length of 69 inches (175 cm) and a width of 42.5 inches (107 cm). The machine has a dry weight of 760 lbs (344 kg). It is equipped with 16x6.50-8 front tires and 23x8.50-12 rear tires, specifically designed for lawn and turf applications to minimize surface damage.
Operational Equipment
Designed for versatility, the tractor supports a 38-inch or 46-inch mower deck. It also includes an optional sleeve hitch, allowing for the attachment of various ground-engaging implements. The operator station is open-style, providing clear visibility and access to the throttle, braking system, and hydrostatic directional controls.
Conclusion
The John Deere 312 is a robust garden tractor suited for landowners requiring a reliable machine for mowing and light-duty utility tasks. Its combination of a hydrostatic drive and a proven Kohler engine makes it a durable choice for collectors and users maintaining medium-sized properties.
