In fact, many sellers will be offended if the buyer doesnât take the sellersâ word for it and insists onweighing the bales prior to the purchase. As a result, the only choice may be to estimate the average weight of the bales. Table 1 lists common bale sizes (width and height) and a calculated estimate of the lbs of dry matter (DM) in bales of that size at different bale densities (i.e., lbs of DM per ft3). Of course, bale density is very difficult to estimate. Most modern round balers will make a bale that is between 9 and 12 lbs of DM per ft3. If the bales are very loose and spongy when pressed, it is likely that
