I am a relatively new GC2310 owner (30 hours) and have never tractored before, so I am learning as I go. I unhesitatingly recommend Little Red if its size and speed meet your needs. It is tough, maneuverable, responsive, and just plain capable.
Re you BH question, it comes off in about 5 minutes. Takes a little longer to put back on. I have done it 4 times with the latest (best) time around 15 minutes.
I have a Gearmore tiller and it performs very well. It was a surprise to see how well the 2310 manages full weight implements.
I have used the BH to plants trees and to remove them. It will pull you into the hole you're digging if you get too greedy with the bucket.
I also have a Land Pride box blade and a Bush Hog auger. I have not used the auger yet, but am looking forward to it. The only constraint with the auger is a 34 inch depth due to the 3 pt being closer to the ground than with traditional large (too large?) rear wheels.
