I used to draw 14 hesstons In straw in England on short draws two High. First eight lengthways, two crossways over the axle, 4 lengthways at the back. Two straps at the front. One strap on the middle lengthways one, two straps at the back. Longer draws (more than 6 or 7 miles) id go 3 high, only one wide at the top as opposed to two, 17 bales. Still 5 straps. The way I looked at it was when I had straps on, I had them mule tight. Then, I could drive as hard as I wanted, (50 k 6130r or 6155r) and never lose them. Silage may be different with big loads.
