The history of John Deere combine harvester

The John Deere Model 55, created in 1947, was a pioneer of modern combines as we know them today. The operator sat at a significant height, allowing full supervision of the wide 3.65m inclined conveyor and cutter bar. Placing the engine at the rear, behind the driver, and the grain tank close to the front axle ensured excellent stability. An additional weight over the front axle and steerable rear wheels improved traction. Although the Model 55 could only harvest 1.6 ha/h, compared to today’s X series vehicles, which harvest up to 12 ha/h, it was a significant step towards harvest efficiency.
Initially, cutter bars were an integral part of the inclined conveyor, and changing them took hours. Combines had to go to the field with the cutter bar attached, limiting their width, especially in Europe. The introduction of the Quick Tach system in John Deere combines from the 3300-7700 series allowed for pulling cutter bars behind the combine and quickly attaching them in the field in just a few minutes. This enabled the construction of wider models with higher capacity, which over the next decade would double the pace of harvesting.
The first cabins appeared in combines in the 1960s, but they were simple and not very comfortable. It wasn’t until 1982 that John Deere grain combines from the 1000 series received modern cabins, which were quieter, better equipped, and equipped with air conditioning. Over the next few years, a range of innovative electronic systems were introduced, providing operators with even greater comfort during work.
