Though I have no experience with kubota.. many rave about the
bx2200 series... Also, a NH tc18 might be nice.. they have a decent looking MMM.. and with only 2 acres.. you don't want a huge tractor runnning around.. unless you are getting more land.
If the 10k includes the loader.. you are gonna be stuck for new on the big 3. However, a used say yanmar with a finish mower and loader easilly fits that budget. Try the yanmar sub for details.
Another option is a chineese tractor... surprisingle you can get the small economy size jinma 20hp version for as low as 3k new from some places... yes this is a bottom of the line economy model.. 2cyl deisel, 3pt lift, no PS. Big dealers in jinmas like norther hyd's sell a jinma with loader and PS as a package for 8499.. unit is a 20hp w/ ps and loader, figure 1100 for shipping truck with a lift gate, and your also gonna pay about 700-900 for a finish mower locally.
That just puts you over your 10k range.. but gets you a 'new' unit, though you would have to be comfterable that it isn't a 'big3' brand name.
Look around.. don't jump into anything.. sometimes you can do some research and walk into a great deal. Check your local dealers, you might fina a used or returned unit that they sold / serviced originally, and get a good deal due to it being a year old with a few hours, etc..
