hi, i'm in ohio too. have just finished a crop tree release on my tree farm. a chain saw is the only way to go if you are doing hundred's of trees as i did. on large diameter trees i would stand in one spot girdle around a quarter of the tree, top and bottom cut, move around tree and repeat till finished. on medium sized trees, walk completely around tree while making top cut, then repeat for bottom cut. for the small stuff just make a felling cut completely though and move to next tree. chaps, glasses, hearing protectors, and a hard highly recommended. i just bought some anti vibe gloves which i think will be well worth the money. good luck.
