Welcome to the board. Your request is very broad - to get any meaningful info, you'll need to zero in on what you want. Another good option is to go to different manufacturers websites and start reading.
Good luck.

I love my Bradco 511 backhoe on my Mahindra 6520. But if I did it over again, I would buy the 7520 (now 8560) for it's 17 gpm hydraulic pump!
