First cutting of seedling year alfalfa will be baled next week, weather permitting. This will be my first time to use a small square bale grapple on the front end loader. The grapple will pick up four, 38-inch small squares wide, 2 bales long, and 2 bales perpendicular at the front end, or 10 bales. I plan to place plastic (mil thickness ???) on the barn floor and stack on pallets. Barn is 50-ft wide and I need to leave room for round bales of grass hay on one side. What is the best way to stack small squares using this grapple?
