The International Harvester 185 Lo-Boy is a compact utility tractor produced between 1974 and 1976 in Louisville, Kentucky. Part of the long-standing Lo-Boy series, this model was designed for small-scale agricultural tasks, grounds maintenance, and property management.
Engine and Performance
The tractor is powered by an International Harvester C60 gasoline engine. This liquid-cooled, 4-cylinder unit features a 59.5 cubic-inch displacement and a 7.5:1 compression ratio. With a rated engine speed of 2300 RPM, it delivers 15 horsepower, providing sufficient torque for light-duty implements.

An optional creeper range is available, extending the configuration to six forward and two reverse gears for tasks requiring lower ground speeds.
Hydraulics and PTO
The hydraulic system utilizes a gear-type pump providing a flow rate of 2 gallons per minute (7.6 lpm) at a system pressure of 2000 psi (137.9 bar). The tractor is equipped with an independent rear PTO, which operates at 1600 RPM in a counter-clockwise direction.
