John Deere sells a front end loader for the X700 series. I'm pretty sure that it will fit all except the 4 wheel steer model(s). There is no backhoe available for the X700's though.
The smallest current model from JD that can take a front end loader and a backhoe is the 2305, which some call a CUT, and others call a SCUT (sub-compact utility tractor). You can get one new with both already mounted for around $16,000.00 to $17,000.00 not including sales tax. There's a SCUT from Cub Cadet that's about the same size and cost for the same setup. Kubota makes one in that price range as well, their's might be a thousand more. I'm sure that there's other brands too.
