A very special video today! On the occasion of the festival of the farmers of Assisi, together with OFFICINA CIANI of Umbertide, which I thank for their collaboration, various models of tractors were tested with a professional dynamometer. In this video we observe the real-time measurement of the power at the PTO and we are able to REALLY observe how many horses every single tractor of different brands and years of construction can unleash under load. The tractors in the video are: CLAAS AXION 950, FENDT 1050, FIATAGRI 160-90 TURBO, NEW HOLLAND TM 130, SAME IRON 130, VALTRA N175, CHALLENGER MT765D, JOHN DEERE 8330, NEW HOLLAND T8040, JOHN DEERE 7710.
