I've bought a scag TT, so the mowing is taken care of, but my new 12.5 acre mini farm is still missing a workhorse. Here's the requirements...I need a good used farm tractor that will pull a backblade, bush hog, etc.....I want a diesel, not gas....and I don't want it to be so old that parts are hard to get. Other than that, I've got about 6K max to spend. Can anybody give me advice...pro's/con's... on HOW to choose one..or what BRAND to look for...or ANY other factors I need to think about...hours,HP, 2x4 vs. 4x4, etc.....as well as what price you think would be fair, or how much you paid for one,,,THANKS IN ADVANCE!!
