I've been doing some of the same. Been hitting stumps here and there when the ground is wet enough to dig, but without the backhoe I'm having to do it with the bucket. Getting ready to order a toothbar to see how much that helps.
I've managed to cut up a lot of the trees we've had down from before we bought the place a year ago and some that fell during storms this last spring. The 1025R has been a champ pulling them off the hill, clearing brush, and pushing piles. It's done more than I thought it would on several occasions.
Even though mine is a new 2-Series, I love how well it digs out those stumps. I have about a dozen more to dig out this coming Spring ranging in size from small to very large... Can't wait to get at it!!
