The tractors aren't hooked in the same place, giving the green one has a leverage advantage.
Plus the green one has eight wheels where the blue one only has six, meaning of the green one has more ground contact. Not a fair test.
I vote for New Holland. My nephew in central Iowa is quite happy with that line of equipment.
