Valmet turned demand for a 190hp model in its Mega range from a necessity into a virtue. The Finnish firm tuned-up its existing 118kW/160hp 8550 model and, with the addition of Sigma Power, changed it into the flagship 8750. This increases the power of the 118kW/160hp 8550 draft work horse into a powerful tractor that can also put out 140kW/190hp at the pto. In this test we find out how this extra 30hp is generated.
