There is a Great Bend in the yard that is used with the
B2910. I think it is worthless. Not that there is anything wrong with Great Bend, or even the model (can't remember the designation and haven't had enough coffee to go out an look). It does what it is designed to do, it digs. No problem with that. But I've found the concept of a TLB to be simply lacking in too many ways, too slow, too small, too inadequate for too many tasks. If you've been reading the forums then you know about the track hoe I rented and the job I got done in a matter of a few hours that would have probably taken 3 weekends with the TLB combo. The rental was about $230 from Saturday noon to Monday morning. I could rent that unit several dozen times and still have money left over instead of wasting the money on a backhoe.
BUT, the problem I see with virtually all tractor mounted hoes is they are really too small to do any real work, combined with the fact that the tractor has to be moved so often when doing any medium to large project that you are constantly moving the whole machine, so attempting any "real" work and you spend more time in the tractor seat moving the whole unit than you really should be. The whole process is a huge waste of time. I'm not talking about popping a stump or digging a hole for a new tree for the wife; I'm talking about doing real work like a foundation, a retaining wall, septic work, or similar type projects.
So if you are going to get a backhoe, buy the biggest honking unit that will fit on the tractor, get the extended reach option, or just RENT a real hoe when you want to do real work.
Bear in mind, some folks have rocks and stumps that need moving, a hoe will do those tasks with great ease. I don't think those folks wasted their money, and I do think that many people find ways to justify spending the money on a hoe and end up happy; I'm not one of those people.
