</font><font color="blue" class="small">( I know that I'm a real newbie here, but I just purchased a 4110 for my 7 acres and it's a heck of a machine. Seems like your tasks are similar to mine. Yeah, if you're sure that you will be getting a backhoe, you might want a larger machine, but for the rest, the 4110 will do it all and save you thousands. )</font>
I have a back hoe(46) on my 4110 and am quite pleased with it. I wouldn't dig a house foundation, but for around the homestead chores, it works great. The 4115 will move the BH a little faster perhaps as I think it has a little more hydro GPM. I'm not sure which model you need to get the 47 BH which is a little larger.
