Oliver 90

The Oliver model 90 is a classic standard-tread tractor known for its rugged design and straightforward functionality. It was built on a 4x2 2WD chassis and featured manual steering and a 4-speed gear transmission. The tractor was powered by a 4-cylinder Waukesha-Oliver engine with a displacement of 443 cubic inches, operating at a rated RPM of 1125. This engine was liquid-cooled and ran on kerosene, a common fuel type for the period in which this tractor was manufactured. It started with a hand-crank, harking back to an earlier era of machinery. The Oliver 90's robust construction led to an operating weight of 7,000 lbs. The model was fitted with 7.50-18 front tires and had options for steel rear tires sized 46x12 and rubber tires measured 13-30. The specific dimensions of the tractor, including its length, width, and height, are no longer available, but its durable build and operating specifications indicate it was designed to handle a variety of agricultural tasks with efficiency and reliability.
