A pleasant surprise
In the development of its Agrotron series, Deutz-Fahr has concentrated less on novel, high-tech features and more on high efficiency with good basic functions. The new shape and the eye-catching cab look ultra-modern, but a close inspection of the individual assemblies shows the tractor is not so radically new.
Consequently when we tested our Agrotron 4.95 we quickly learned to handle the tractor quite “normally”, before going on to discover the many improvements, but also some weaknesses.
The 4.95, at 70kW/95hp, has the most powerful four-cylinder engine in the new series. With a relatively modest cylinder capacity of only 3.2 litres, the engine has an intercooler as well as an exhaust turbocharger. Alongside the 4.95, the 6.00 model from Deutz-Fahr offers the same performance from a 4.8 litre capacity, six cylinder unit without intercooler. The performance data on the Agrotron 4.95, provided for us by the DLG test ation, certainly shows the smaller engine measures up in its own right.
At rated speed (2,300rpm), the tractor delivered a maximum pto power of 63.5kW/86.2hp, but as the enginerevs reduced, the pto power increased significantly.
The maximum pto power at 2,100 rpm was a creditable 69.7kW/94.6hp, and only atless than 1,750rpm did the pto power fall below the rated speed value. The measured values therefore show a constant performance range of almost 24%, with almost 10% or 6.2kW/8.4hp extra power. The 34.8% torque increase at 34.8% reduced rpm is also good. So far, so good, as far as the engine is concerned.
Fuel consumption, both at maximum output and at typical performance rates, was in the medium
