Info

The Dronningborg D 7000, introduced in 1980, had a 12-14 foot cutting platform and a 105-120 hp engine. Considering these specifications, its threshing system was quite robust. The threshing cylinder width was 140 cm. The threshing system featured a replaceable cylindrical sieve and a fan-based after-cleaning mechanism that cleaned the grain before it reached the grain tank. Like other new Dronningborg models, the cab was positioned on the combine's centerline. Unlike the smaller models, the sieves were adjustable and the unloading auger joint was sealed. The speed of the threshing cylinder was hydraulically controlled.

As an optional accessory, a Power Flow cutting platform was available, which included a belt conveyor between the blade and the feed auger, improving feed consistency and making it easier to harvest tall crops. The electronic monitoring systems were more comprehensive than those on smaller models, and additionally, the D-Control system—later named Unicontrol—was available as an option. This was the most versatile combine computer of its time. The Unicontrol system displayed, among other things, the harvested surface area, threshing time, instantaneous driving speed, rotational speeds of eight axles, as well as alarms for rotational speeds and fluid levels and temperatures of the engine and hydraulics. Furthermore, the system could be expanded with a loss meter and a threshing power/yield meter.

In 1984, Dronningborg introduced new models under both the MF (Massey Ferguson) brand and its own name. The D 7200 and D 7500 models were equipped with Valmet engines—unlike the MF models—and featured larger concaves and grain tanks compared to the D 7000. In 1990, the D 7800 was introduced, and the D 7500 also grew in size, including its concaves and sieves. These models had hydrostatic transmissions, available in both two- and three-speed versions. Starting in 1987, combines were also sold in some countries under the Case IH brand. In 1990, the color of the Dronningborg models changed to a more reddish tone. From 1992 onwards, combines were produced solely under the MF brand, and the Dronningborg brand went into history.

Among the Dronningborg models imported to Finland, the D 7200 was the most popular and came standard with reverse rotation and an electric clutch for the threshing mechanism. Most of the combines also featured Unicontrol, which was a standard feature on the more powerful D 7500.
