The First Water-Cooled Deutz Tractor - Deutz AgroStar 6.81

In this Tractor Central video, I break down the Deutz-Fahr AgroStar 6.81, a German-built row-crop tractor manufactured from 1992 through 1997, and explain why it marked a real turning point at the top end of the AgroStar lineup. The 6.81 is rated at 185 horsepower and runs MFWD, a standard air-conditioned cab, and a 100.4 gallon fuel tank, but the headline story is under the hood. Instead of Deutz’s traditional air-cooled identity, the AgroStar 6.81 uses the DLG-identified MWM TBD 226 BL-6, a water-cooled, turbocharged, charge-air-cooled six-cylinder diesel with 7,014 cm³ (7.0 liters) of displacement, 105 mm by 135 mm bore and stroke, and a rated engine speed of 2,350 RPM. This video also digs into the numbers that matter in the field, including DLG-tested performance figures of 174.6 PTO horsepower, 149 drawbar horsepower, and 533 lb-ft of maximum equivalent torque at 1,200 RPM. I cover the transmission options, including the standard 18 forward and 15 reverse speeds and the optional creeper setup with 27 forward and 15 reverse speeds, along with the 25 MPH top speed. We also go through the implement-side specs like 21.1 GPM hydraulics at 2,727 PSI, a rear hitch rated Category II or III with 17,640 pounds of lift, an optional Category II front hitch with 7,720 pounds of lift, and PTO configurations including 540/1000 and 1000 options. Finally, I explain the 2026 European used market pricing for the AgroStar 6.81, from €13,500 to €49,999, which converts to roughly $15,952 to $59,079 at a February 26, 2026 exchange rate of 1.1816, and why these tractors are so rare in the United States. #TractorCentral #DeutzFahr #DeutzTractors
