Introduction
Oliver 99 Standard-Tread Tractor
The Oliver 99 is a standard-tread tractor produced between 1937 and 1953, with later iterations forming part of the Super 99 series from 1954 to 1958. Designed as a heavy-duty agricultural machine, it served as the successor to the High-Compression Special 28-44 and was manufactured in Charles City, Iowa, and South Bend, Indiana, USA.
Engine and Performance
The tractor is powered by a 302 cubic inch (4.9 L) Waukesha-Oliver 6-cylinder liquid-cooled gasoline engine. It features a bore and stroke of 4.00 by 4.00 inches (102 x 102 mm). The engine is rated at 69 horsepower, with operating speeds ranging between 1125 and 1675 RPM. Starting is primarily achieved via a hand-crank mechanism, though electric start options were available.
Transmission and Drivetrain
The Oliver 99 utilizes a gear-type transmission providing 4 forward speeds and 1 reverse gear. Power is transferred through a dry disc clutch to the rear wheels in a two-wheel-drive configuration. This setup allows for controlled power delivery during standard field operations.
Hydraulics and Power Take-Off
The machine is equipped with an optional independent rear power take-off (PTO). This system operates at a standard speed of 540 RPM via a 1.375-inch shaft, providing the necessary mechanical power to drive various towed or mounted agricultural implements.
Dimensions and Mechanical Controls
The tractor features an open operator station with manual steering and contracting band brakes. It has a wheelbase of 80 inches (203 cm) and an overall length of 125.75 inches (319 cm). The operating weight is 7,073 lbs (3,208 kg), which can be increased to 13,110 lbs (5,946 kg) when ballasted for heavy traction work.
Conclusion
The Oliver 99 is a robust, classic agricultural tractor suited for heavy-duty field tasks. Its high power-to-weight ratio and simple mechanical design made it a staple for mid-20th-century farming operations, remaining a significant model for collectors and historical machinery enthusiasts.
