I've owned and/or operated a New Holland LX865 skid steer (big one), Case 580 series backhoe, Ford BIG backhoe, and now a Kubota
L48.
I don't do construction work, but I got an idea of how they would operate doing some of the jobs you might do.
I can tell you NOTHING can keep up with a large skid steer doing loader work. They are simply designed to that and do it fast and accurate. I wouldn't want to dig with them and I think a backhoe attachment on one would be a joke compared to a
L48 or Full Size TLB, but loader work they are king!
As for the
L48 or full size. I choose the
L48 route, but only because I wanted a TRACTOR with the ability of having a 3 point "box blade, tiller, etc" on it. I have a Larger tractor that does most of my tractor jobs, but it's Cat2 and non-shuttle making some task difficult to do with it. I will keep the large tractor for most field work and use the
L48 for loader and small precision 3 point jobs. I will rarely use the back hoe, so it will be off the machine most of the time, but is easily put back anytime I need it.
My decision for
L48 was pretty easy because of the requirements I set forth. I wanted a machine I could easily take the backhoe off (Full size out here), I wanted to transport it easily using my 1 ton pickup and 14k trailer (Full size out here), I wanted a machine built as tough as a normal backhoe with good FEL speed and strenth (Compact tractors out here). That left the
L48, John Deere 110, and Ingersol Rand machines to look at. I ended up with the
L48 out of the 3 because I found one close at a reasonable price used.
So far I'm very happy with my
L48. If I was going to be diggin footing, basements, septic systems, etc for a living, I would without a doubt get a full size TLB. It would save you a month or more of time out of a year. If I was digging my own footing, basement, and septic, I wouldn't rule out a
L48, but would look carefully at the long term plan of where I wanted to end up machinery wise after I was done. I would probably try to buy a Full size TLB at a GOOD price then sell it when done and get a tractor or
L48. Or if I found an
L48 at a good price now, it would get the job done, just not as fast as a Full size.
My 2 cents worth.
