ENGINE DETAIL
The Oliver 90 tractor, equipped with a 443 ci Waukesha kerosene engine, offers efficient performance with a displacement of 7.3 L and a low rated RPM of 1125, making it suitable for steady, power-intensive tasks like plowing or tilling. Its oil bath air cleaner enhances engine longevity by improving filtration under varying dust conditions, but the hand-crank starter can pose usability challenges, especially in colder climates, despite the optional electric start. This tractor's robust construction provides reliability in agricultural operations, yet potential owners should consider fuel availability and operational needs to maximize efficiency.

OLIVER 90 ENGINE
The Oliver 90, featuring a Waukesha-Oliver 7.3L 4-cylinder kerosene engine, provides robust power for agricultural tasks, delivering approximately 45 horsepower. Its capacity to run on kerosene can offer cost savings in fuel, but may require careful handling and adjustments for optimal performance compared to gasoline models. The tractor's vintage design also poses challenges in parts availability and modern compatibility, making it ideal for collectors or enthusiasts but potentially less practical for daily use in contemporary farming.
