The G107D is our least-cost “full-featured” tractor, with all the transmission ‘bells & whistles’: 3 working speeds plus transport speed in “trailer-pulling” direction, differential with lock, and steering brakes. The slightly smaller HP engine choices and slightly older-fashioned controls keep the cost lower than the Grillo G110 and BCS 749 / 853 . it will not handle quite the range of implements these larger tractors will, due to less available power, but it still handles over 90% of our implement range.
