" Place the bales onto the pallet on their sides with the cut side up. Line them up evenly, side by side, until you fully cover the pallet with a single layer of bales. If stacked properly, the strings will be on the sides, rather than the top and bottom. This allows for better air circulation. When a bale is on its side, the hay stems should run vertically. The top of the bale will feel sharp and jagged. " The second layer needs to be placed perpendicularly to the first, with all the bales placed width-wise. This time, the strings will be on the top and bottom rather than on the side. You can usually put them loosely in their spot and kick them firmly into place, especially if it's a tight spot. You can also shove the bale in with your knee, which would be safer. Make sure the bales are packed in as tightly as possible. Tightly packing the bales helps prevent unstable stacks. The orientation of the bales (cut side up) allows for circulation. If your bales are still green, pack them in a little more loosely. Alternating the direction allows for good air circulation and results in very stable stacks. Changing the direction each time locks the bales in together, almost like puzzle pieces, with great stability. This is the simplest and easiest way to stack hay. Vertically, the bales will form four-bale columns, and between these columns, the stack can collapse. If your stacks are four bales or fewer, this won't be as much of an issue. Cover the pallet with the first layer, then start building stacks from the corners toward the middle. Make sure to keep the corners or each new stack perfectly lined up with the corners below to assure stability.
