Info
The 40-series European tractors were introduced at the end of 1979. All 3-cylinder models were now 2.9 liters. The transmission was the familiar 8+4 (with Hi-Lo quick shift, making it 16+8), but it was now synchronized. The quick shift had been improved so that the tractor could now be started by towing and parked with the gear engaged.
The cab was the familiar Sekura product, and the gear levers were positioned in the center. The steering in the three-cylinder models was not hydrostatic. In 1981, the front axle was replaced with a more agile one.

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.
