It should be noted that figures above are approximate only and that actual dimensions of bales can vary considerably from the expected, due to variations in dry-matter content of the grass being baled and the pressure that balers can exert.
A more accurate figure can be obtained by measuring the actual circumference of 20 bales which are representative of the bales in the field and obtaining the average diameter.
Note that a 6" increase in diameter on a bale increases the circumference of the bale by 0.479m, nearly half a metre! This will reduce the number of bales covered per roll by as much as 25 (assuming a 4ft bale with 2 layers applied). A similar exercise needs to be performed with the length of net being applied. Whilst it may be considered that exactly 2 layers of net are being applied, one extra metre of net applied to each bale would reduce the number of bales per roll by as many as 39 bales.
