Dronningborg D-950 – D-1650

The very old D-900, representing 1950s design, was updated in 1976 into the angular D-950. New features included, among others, hydrostatic steering, a fully adjustable seat, and a differential lock. The basic technology remained the same: the engine was located beside the driver, and the fuel tank was positioned above, on the right side of the grain tank. The top sieve was fixed size as standard, there were two gears, and the speed was controlled by a foot pedal.

In the larger models, the updates were more significant. The rear end of the combine harvester had been widened, meaning that, as with certain MF combines, the threshing elements and sieves were wider than the front end of the threshing unit. In the D-1250, the threshing elements were also longer than before, and the cutting width was increased to 10 feet. The grain tank was raised. A cab with tinted windows was also available.

Regarding the diameter of the threshing drum, 43 cm was considered sufficient, even though the first larger models had a 58 cm diameter. The use of a hydraulic unloading auger was still rare technology in a mid-range combine.
