BH65 Backhoe w/ thumb:
Not a whole lot of seat time on the backhoe. Part of that is it makes quick work of what I've thrown at it. Right off the delivery trailer I used it to dig up a 8" dogwood stump. Not huge, but it literally took 3 or 4 scoops to haul it out cleanly, even with me fumbling at the controls. Would have taken forever by shovel to due it. The clay is dense and hard.
I was talked into the 16" bucket and was glad I did. Its not overly large, but the BH has plenty of power for it and it makes quick work of things. The only thing I don't like is certain movements with the boom and dipper can't happen at the same time.
The backhoe's actually pretty nice compared to many other CUTs out there. The basic problem is that the tractor doesn't have a whole lot of hydraulic flow - you might practice with the RPMs up so it's more obvious what controls can be easily paired (and the answer is basically any of them). The trick comes with feathering the controls properly, and takes a bit of practice, again, because there's not a lot of flow in the system. Even with the RPMs up, you need to feather the controls precisely to keep the BH action smooth and free from jerkiness. You should be able to curl the bucket, crowd, and raise the boom simultaneously. Try that on some of the competing compact utility tractor backhoes- it's not happening.
