Replying to the initial post in this thread--Actually your $10K budget is not unrealistic for your 30 acre farm. Here's what I have for my 10 acre place (6 acres of hayfield) including real life prices paid.
-1964 MF135 diesel tractor ($3600 bought in 2006, 45 hp engine, 37 hp pto)
-MF 124 baler (two twine, small squares, $2000 in 2009, in great condition--bought it right out of the field from the seller who baled 30 acres the day before I picked it up).
-MF 31 sicklebar mower (7-ft cutting bar, $550 at auction 4 years ago, about $250 in replacement parts)
-JD 350 hay rake (10 ft wide, 5-bar side delivery type, 3pt hitch/pto driven type, $800)
-Cultipacker (10-ft wide, $600)
-Minneapolis Moline P3-6 grain drill (paid $275 for two of these, used parts to make one good drill, about $300 in new parts)
-Minneapolis Moline KS1300 wheel disc (aka transport disc, 13 ft wide---I cut it down to 8 ft wide so my smaller tractors in the 45-55 hp range could handle it, $600)
I've also made assorted drags to smooth out the clods in the hayfield after discing and before planting.
Hope this helps
Good luck
