Introduction
John Deere 322 Garden Tractor
The John Deere 322 is a garden tractor produced between 1988 and 1992 in Horicon, Wisconsin, USA. It serves as a liquid-cooled evolution of the established John Deere 318 model, integrating a three-cylinder Yanmar engine to enhance performance and thermal management for residential and property maintenance tasks.
Engine and Powertrain
The tractor is powered by a 658 cc (40.2 ci) liquid-cooled, inline three-cylinder Yanmar engine, producing a gross power output of 18 hp (13.4 kW). The engine utilizes a compression ratio of 8.7:1 and features a dry element air cleaner. Power is delivered through a Sundstrand Series 15 Model 90 shaft-driven hydrostatic transmission, providing infinite forward and reverse speed control.
Hydraulics and PTO
The hydraulic system features a 6.2 L (1.625 gal) capacity and includes two valves for implement control. The tractor is equipped with independent front and rear power take-off (PTO) capabilities. The front PTO operates via a pulley system with an electric clutch, while the rear PTO is optional and rated at 2000 RPM.
Chassis and Dimensions
Built on a two-wheel drive chassis, the 322 features power steering and mechanical drum brakes. It has a wheelbase of 116 cm (46 inches) and an overall length of 176 cm (69.5 inches). The machine is designed to operate with various mower decks, specifically 38, 46, or 50-inch configurations, supported by lawn and turf tires.
