A local (central IL) dealer has 2 machines I'm considering for mowing, brush cutting, and light to moderate loader work on 108 acres. 1st is a 2005 3720 with 300cx loader and 72" mmm, asking price is $21k. 2nd is a 2007 4320 with 400x loader and no mmm for $22k. Both machines have between 800 - 900 hrs. Assuming they are mechanically OK, do these prices seem reasonable?
