Case IH Magnum Series

03/23/2011 @ 3:18pm

In 1987 the newly formed Case IH company, created from the merger of Case and International Harvester in the fall of 1985, announced that they were working on an entirely new, “from the ground up” design in a tractor series. The dealerships of the new company had been selling a compilation of Case- and IHC-designed tractors after the merger and were clamouring for new horsepower

Case IH engineers didn’t let them down. The fall of 1987 dealers were gathered in Denver, Colorado, to witness the new line, dubbed the Magnum series of tractors.


The Magnum 7100 line consisted of four tractors – the models 7110 (130 hp.), 7120 (150 hp.), 7130 (170 hp.) and 7140 (195 hp). – which employed six-cylinder turbocharged engines design specially for the tractors by Consolidated Diesel Corporation. This engine firm was jointly owned by Case IH and Cummins.

Besides the tractors’ distinctive styling, what set the Magnum apart from any other tractors on the market at the time was the series 18-speed full powershift transmission which was offered at standard equipment. Standardizing a full powershift was a first in the industry and would inspire other tractor manufacturers to quickly follow suit to compete with the new Magnums.

Other improvements which marked the Magnum as a trend-setting machine included its Silent Guardian II cab – which set new sound reduction level records in the industry – as well as the location of the engine’s muffler on the right front corner of the cab to provided an unobstructed view over the tractor’s hood.

In 1991, Case IH added a fifth model to the Magnum series in the 7150 which, at 218 horsepower was the highest horsepower front-wheel-assist traxtor in the world. The Magnum name continues to be used on Case IH tractors today. In fact, the 50,000th Magnum was produced in 1994 and 100,000th Magnum sold in 2003.
