I had a Haybuster and it worked well if cornstalk bales were dry, but then wet bottoms and tops from sitting outside made for a lot of rocking the bale back and forth to get it to bed. Also took a lot of power. I bought an Anderson Pro Chop. Same issues with wet bales but takes a lot less power and blows farther.  Not  very friendly to load especially 5X6 bales. Moral of the story keep your bales dry and either will work well. I had a tornado take down my 2 bedded pack barns in May. I will not be rebuilding and the Anderson is for sale in WC WI.
