Overview & History
The Case IH 7140 was one of the first tractors launched under the Magnum series, which was created just after the Case and International Harvester merged. Built from 1987 in Racine, Wisconsin, USA, this row-crop tractor had a PTO rating of 195 hp. In its final production year (1993), it was last sold for US$ 91,000. It was eventually replaced by the Case IH 7240 tractor.
The heart of the 7140 was a six-cylinder Cummins-built engine that was known to be compact, strong, quiet, and fuel-efficient. The 8.3-litre displacement offered a lot of reserve power and good torque rise to help the tractor run through the toughest terrain. The intercooled, turbocharged diesel gave the tractor an added power boost without the stress.
The modern engine design resulted in 25 percent fewer engine parts used for greater simplicity and service economy. It had a 114-millimetre bore, 135-millimetre stroke, vertical inline liquid cooling, viscous fan cooling system, and dual paper elements air cleaner. An ether starting aid was the standard pre-heating, but block heater and oil pan heater were made available as options.
This engine had 16.5:1 compression ratio, ran at 2200 rated RPM, and gave the 7140 a 12-volt starter. Its oil capacity was 20 litres, coolant capacity was 29 litres, and fuel capacity was 360 litres. The engine oil required changing every 250 hours, which was a longer interval than what was usual back then and thus promoted lower operating costs.
The 7140’s rear hitch was a III/IIIN type and moved using an electronic lower link control. It can lift objects up to 4,626 kilogrammes at 610 millimetres.
The transmission system in this tractor was either an 18-speed full powershift or a 24-speed powershift with creeper. The 18-speed was operated with a single right-hand control lever and had a smooth and easy straight-line shifting pattern. With this transmission, the operator could start in any gear and shift up, down, and reverse without clutching. Due to customer feedback, two reverse gears were added beginning with the 1990 model year.
Meanwhile, the optional creeper range added another six forward gears and one reverse to the powershift transmission. It was especially suited to slow-speed operations like pull-type PTO-driven combines and forage and vegetable harvesting. The reverse gear was great for snow-thrower operation. A handy park lock was provided to both systems.
The Case IH 7140 tractor, along with the rest of the Magnum 7100 range, proved to be extremely reliable. However, operators discovered an issue with the exhaust system in earlier models. These units were fitted with a flat casting covered by a sheet-metal heat shield, which ended up collecting stray cotton that caught fire. To solve this, Case IH’s engineers replaced the flat casting with a round, formed steel tube that let the stray cotton fall off.
This change coincidentally gave the later models a better engine performance. And the first generation of the Magnum series set new standards for high-powered tractors around the world.
