Last Updated: July 2024

Overview

The Oliver 1655 is a row-crop tractor that was available in both 2WD and 4WD configurations. It featured a liquid-cooled Waukesha-Oliver inline 6-cylinder engine with a displacement of 283 ci for the diesel variant or 265 ci for the gasoline variant. The engine produced a maximum power output of 92.64 hp at 2200 rpm and a maximum torque of 259 lb-ft at 1488 rpm. Known for its reliability and versatility, the tractor offered power steering and disc brakes for improved control. The 1655 model was equipped with a Hydraul-Shift partial power shift transmission providing 18 forward and 6 reverse gears or a helical gear transmission offering 6 forward and 2 reverse gears, both utilizing a dry disc clutch. With an independent PTO and an open-center hydraulic system, this tractor could manage a range of attachments and implements. Optional cabin features included a heater for operator comfort. The Oliver 1655 demonstrated excellent fuel efficiency, achieving 14.97 Hp.hr/gal at rated speed, 14.26 Hp.hr/gal at the standard PTO speed of 540 rpm, and 12.68 Hp.hr/gal at the standard PTO speed of 1000 rpm during independent testing. The tractor was a prominent figure in agriculture during its production years from 1969 to 1975.
