The BX23 (like the BX24 and BX25) comes with an integrated backhoe attachment that has a swivel tractor seat that is utilizes for both driving the tractor and the backhoe.
Removal and installation of the backhoe is relatively quick and painless once you get use to it. The tractor is light and the backhoe is strong enough to wag the dog.
The only complaints I have is that the transmission fill port and dip stick are very difficult to get to and the turnbuckles for the three point hitch are wimpy and tend to get bent. These problems are minor and can be worked around. I replaced the turnbuckles with larger ones and bought a long neck oil funnel.
A friend who use to borrow my tractor liked it so much he bought his own BX25 which says a lot for the tractor.
