If you get a 110 or
L45 either will remove most stumps. I would see how many I could get out first and leave the remaining stumps for a large backhoe such as a Deere 710 or Cat 426 size machine. My reasoning is there are a lot of these older backhoes around and you may find an owner operator that can remove these remaining stumps at a lower cost. For all but the largest stump removal the 110 can easily handle the rest of the clean up.
Used as a tractor with three point hitch and three rear hydraulic outlets it seems to work well in my use. Worked pretty well with my MX6 mower and 673 tiller as well. Using a 110 as a tractor does have one limitation, I found that for high draft loads not having extra rear wheel weights can be an issue. Deere does not recommend adding weight to the rear wheels using the backhoe. You will experience more wheel slip pulling a heavy box blade than my weighted 4520. While both machines will work the 4520 will do a better job.
That said above I would recommend the 110tlb and would also recommend the
L45 and larger
M59 tlb.
Edit, With 1000 stumps to remove or 200/acre the $2000 /acre for stump removal and clean up seems reasonable to me. Larger equipment would be a more cost effective way to go.
