Introduction
Gravely 432 Garden Tractor
The Gravely 432 is a garden tractor manufactured by Gravely between 1967 and 1972. Designed for residential and light-duty landscaping applications, this two-wheel drive machine features an open operator station and is part of a series that includes the 430 and 450 models.
Engine Specifications
The tractor is powered by a 14 hp (10.4 kW) single-cylinder, air-cooled engine with a displacement of 512 cc (31.27 ci). It utilizes a horizontal-shaft configuration and features a single dry element air cleaner. The engine operates at a rated speed of 3600 RPM and requires 2.5 quarts (2.4 L) of oil for lubrication.
Transmission and Drivetrain
Equipped with the Swiftamatic 8 system, the transmission provides four forward and four reverse gears. Power is transferred through a shaft-driven gear arrangement utilizing a friction cone clutch. The system requires SAE 90W-EP oil. A two-speed shift-on-the-move feature adjusts both transmission and PTO speeds, while an additional two-speed range is available when the tractor is stationary. Directional control is managed by a right-hand lever.
Mechanical and Dimensions
The chassis features manual steering and mechanical band brakes for operator control. The tractor has a wheelbase of 46 inches (116 cm) and a shipping weight of 900 lbs (408 kg). Ground clearance measures 10 inches (25 cm) at the front axle and 6.375 inches (16 cm) at the rear. It is typically fitted with 16-6.50x6 front tires and 23-8.50x12 rear tires designed for lawn and turf use.
