Welcome Andrew,
I agree with Roy, and Thomas both. I'm in the same boat that you are with about 3 acres to mow. I've got a NH TC21D, and anything bigger would be very rough to manuever. The 4010, and 4100 would do nicely. I think the 790 would be a bit too big. I say this because originally, I thought about buying one. The other brands offer some great smaller compacts too. As Roy mentioned the Kubota BX model, and NH TC 18,21, the new 24 would be good choices. Hazmat, and Solo have TC 18, and I don't think anyone has a TC24 yet. There are many BX owners, and quite a few Kubota 7000 series owner. All these would work for you. Buy the best tractor that suits your needs , and stay in your budget. With 2 acres of mowing, and loader work, I won't go much larger then the smallest class compact, or a sub-compact. Good Luck,
Kent
