"Developed in conjunction with the McCormick model, the first Deering experimental harvester-thresher was built in 1913. The design for the Deering No. 1 became the basis of future International Harvester Company harvester-thresher combines. Photo credit: Wisconsin Historical Society #45642

1925

Marking the transition from old-style harvester-threshers of the No. 4 and the No. 5, the modern and efficient machines of the No. 11 type dominated the harvest landscape. Photo credit: Wisconsin Historical Society #45641

1935

The No. 36 harvester-thresher was designed to be powered by a 7- to 14-hp tractor belt pulley or stationary engine. Designed with the small-acre farm in mind, it could be configured with an optional trailer attachment so it could be transported. Photo credit: Wisconsin Historical Society

The No. 141 Hillside combine was the first machine to level hydraulically with a system to level the platform both fore and aft as well as side to side. Photo credit: Dave Gustafson

1964

The McCormick-International 203 was equipped with twin grain tanks, dubbed “saddle tanks,” that lowered the center of gravity. In five years of production, 5,135 were built. Photo credit: Lee Klancher

1977

In 1977, International Harvester Axial-Flow combines start using a single, large-diameter rotor for the threshing and separating process. This system eliminated the cylinder, beater and straw walkers of conventional combines.

1986

Introduced by Case IH in 1986, the 1600 series featured increased grain-tank capacity, larger concaves and more separating area than the 1400 series combines. Photo credit: Lee Klancher

1996

A decade later in 1996, the Case IH 2100 series introduced a new cab, a more efficient hydraulic system and an increased power system. Photo credit: Rachel Wegman

2009

The 9120 Axial-Flow was the industry's first class IX combine, had a 12.9-liter Iveco engine rated at 483 hp and introduced the 126-knife MagnaCut™ chopper along with other features, including optional heated red leather seats.

2015

Today's Axial-Flow® 140 and 240 series combines are proven to produce the highest grain quantity and quality to meet the needs of any operation.
