I had a '95 580 SL and a '98 310 SE both at the same time. The 580 would out dig and out lift the 310, 310 would out push the 580 on the loader end, just because the 410 was 4x4 and the 580 wasn't. The 310 had a 4in1 loader bucket which was kinda nice, and it was an extendahoe also which my 580 wasn't. I didn't really care for the curved boom on the 310 myself, I grew up on excavators which have the curved booms, but it just didn't "feel" right on a backhoe to me. I'm not really a big Deere fan myself (mainly due to the local dealer) but having said that, if I couldn't go with a Case, I would probably go with a Deere. I've been on a couple of Cat machines, and wasn't really impressed. I've been on a couple of JCB's, (1990 vintage) and didn't care for them. Terex and Komatsu both seem bulky and awkward. Terex I've been on had a lot of power, but was really slow.
