I'd love to have a 3110D, but ended up with a 2210BD (26 engine HP).
I do all the things you mention with the exception of operating a brush hog and tiller. I do operate a 72" snowblower on an all to routine basis in the winter though; and I have no real complaints. I'd run the tiller in a heartbeat..was made for those things.
A spear on the 3 point would be better for moving the round bales, but I also seasonally move 100" logs on my forks which must add up to 5-600 pounds. Granted im not moving them very far and on flat terrain. When i am in the woods hauling firewood i cut 30" pieces and stack them in the bucket long ways. Sometimes I run all the way home like that, sometimes i dump them onto a trailer. The beauty running all the way home is when you go to stack. Pull up to where you need to be and adjust the height to where you need it. I rarely handle a piece of wood more than a few feet when it comes out of the bucket, frequently less.
My property sounds a smidgen hillier than yours. Currently i am running Ag tires, set wide, and use cement weights in the rims. I plan on putting turf tires on soon. I never push my limits side sloping and keep it straight up and down, or cut a new path with the bucket. I wouldn't be able to do 1/2 the operating I do on the hills without 4wd.
The bucket on this tractor is....tiny. It's nice because I can cut into the ground, but somewhat disappointing in the volume it will hold. To haul bulk materials (leaves/much/compost) I have a section of aluminum arch culvert that I set onto my forks and hold it there with a cable. Figure I can get about 3/4 yard of light materials in it.
I bought my tractor mainly to remove snow and to help with the firewood. It does all that I ask it to, but I wouldn't go smaller and between the snow and hills I wouldn't go without 4WD. Oh and read what Hoye says about the 2210:
