I have an Anderson Pro Chop. It handles wet bales better than the Haybuster I had before and blows farther. It is faster with waaaay less power because knives cut  and hammers just try to beat it apart(corn stalks). It works with square or round bales. Negatives are that you'll want to remove net wrap first and not big enough for 2  6' diameter round bales(5 1/2' OK). It also does not self load, but Teagle makes similar style processor with self loading.
