Introduction
Oliver 770 Row-Crop Tractor
The Oliver 770 is a row-crop tractor manufactured in Charles City, Iowa, USA, between 1958 and 1967. Designed for general field operations, this two-wheel-drive machine represents a key mid-range offering in the Oliver product line during the late 1950s and 1960s.
Engine and Power
The tractor is powered by a liquid-cooled, 6-cylinder Waukesha-Oliver engine with a displacement of 216.5 cubic inches (3.5 liters). It operates at a rated speed of 1750 RPM, delivering 52 horsepower. The engine configuration uses a 3.50 by 3.75-inch bore and stroke, providing consistent performance for various agricultural tasks.
Transmission and Drivetrain
The transmission system features two primary configurations: a standard 6-speed sliding gear transmission with 2 reverse gears, or an optional 12-speed Power-Booster transmission with 4 reverse gears. Both setups utilize a dry disc clutch to manage power transfer to the rear wheels.
Hydraulics and Hitch
The Oliver 770 is equipped with an independent rear power take-off (PTO), which allows for the operation of implements independent of the tractor's ground speed. It features a rear hitch categorized as Type I/II, ensuring compatibility with a wide range of standard agricultural implements.
