I have a 1710 but bought back in November and am now just getting to use it. 5 foot attachments covers my wheel tracks. The tractor seems to have good power. I pulled a 5 foot field cultivator and with the use of the 4wd I pulled it pretty deep so I think you could handle a 6 ft box blade. It will handle all attachments you want to use. I do not know about a backhoe though I'm not all that sure of the hydraulic pump capabilities or the stress that puts on the tractor I'm sure it was not designed with those kind of stresses in mind. The front and back ends are joined together with bolts. (backhoes do a lot prying and trying to lift the front wheels off the ground putting pressure on the connection between the back and front)

With that said I haven't dug any rocks or tree stumps so I cant help you there. I'm confident that with the right ballast on the back it could lift the stumps from the ground once the roots were cut away.
