GW,

I have the same tractor except 35hp.

It has 500h on the meter, and it's been good so far. I think the 45hp will handle mowing and maintenance real good up to 15a, but 20a would be pushing it, depending on the chores. My 35hp is almost maxed out on a 6' bush hog and 55" disk harrow. I think the 45hp model will pull a 7' bush hog and a 6' disk harrow just fine. It will pull a 9' finish mower no sweat. The 17LA loader is a good implement, and I have really punished mine.

The reason I chose NH over the other popular brands was the tractor size. For a given HP, the NH has bigger tires and a bigger frame. Compared to the NH, the other 35-45hp tractors look a lot smaller.
