Info
In the autumn of 2007, the largest innovation in John Deere's renewed combine harvester lineup was the T series. It was strongly based on the W series, but had a total of four reels. A special feature was the second reel, which rotated in the opposite direction compared to the other reels and transferred straw over the top to the third reel, which had a diameter of 66 cm, the same size as the front reel. The fourth reel was a similar 40-centimeter reel replacing the straw reel, as in the W series. The T series models had higher engine power than the W series.

The data has been collected primarily from brochures. In some cases, sources contain conflicting information. In such cases, we have attempted to select the most reliable information.
There is particularly significant variation in speed data, which varies depending on factors such as tire size. For tires, only the size most commonly used in Finland is listed.
Other changes during the model history have been addressed in the text section. For the front axle lock, the Finnish term "hammaslukko" (gear lock) is used for all 100% locks.
