Some stands are planted on 8' or 10' rows, and square balers can be used there. The manual process yields 250-300 bales per day and the mechanical process yields as many as 1000 bales per day. We discovered that our Mini Roll Baler fits well, even in 6' center rows. Not at this time. We're bringing in a small hay rake to test this summer.
Most rakes are too big to take into the trees.
They're not for everyone. For Grandma's 2 or 3 rose bushes they may not be economically feasible. However, large homeowner landscapes and landscapers who have tested the bales liked them and wanted more. After baling the straw, or more aptly before baling, the operator should have the bales sold, preferably by long term contract. It would be ideal to deliver directly from the baling process, thus eliminating any storage and additional handling, but that's not always possible.
