I have 11 acres of rolling land (some really steep)and a 2320 tractor. I love the thing. It mows, grades, tills, and loads perfectly for me. Yesterday I mowed for the first time this year while pulling a loaded 4 foot roller. The tractor lugged a bit coming up hill, but not to bad. But hey, going down hill was a breeze! And I love the cruise control.
My biggest concern with the 2320 is how it feels going cross hill while mowing. It feels a lot more tipsy than my old L118 did. But I'm getting used to mowing up and down and all is well.
I agree with NURU though. If I decided to trade, I would go up into the 3000 series where there is "More Power"
