The 66 uses the smaller NH_Genesis engine, I think rated around 260-270 if memory serves me well. 68 has heavier drives and bigger hopper. My $.02... both are good enough machines and excellent engines. Great on fuel. We ran a 66 for many years with a 315bu. hopper with no problems. Never short of horsepower. Always reached it's limit in other places first. like every model_color, they have strengths and weaknesses. Overall, a good machine. Pilgrim
