The weight of the made-up bale hay depends on the kind of crop species and how it was prepared and wrapped up. The animal feed can be packed in square or round hay bales and its weight will vary depending on the equipment and its settings.
However, there is no common “standard” for hay bales and balers, which work during the hay harvest, can form them in different sizes, and, consequently, in weight. Everything depends on the capabilities of the equipment and the settings that the operator has set.
We asked our customers about the hay bale weight and averaged the findings. The result is the following: the modern world’s leading brands balers bale dry wheat hay with a density of about 130-140 kg/m3 into cylindrical hay bales and about 160-170 kg/m3 in large square hay bales. It is possible to bale the wheat hay with a higher density of 15%.
If we have the density of baling and know the size of the hay bale, we can easily calculate the weight of 1 straw roll on particular equipment.
We can find out the weight of cylindrical hay bale with 1.2 m width 1.5 m in diameter using the formula:
M= v*p, where
p = density,
m = mass,
V = volume.
For a cylindrical hay bale, the calculation is slightly different:
М= 3.14*r2*h, where
r = radius of the cylinder,
h = height.
If the straw roll is not baled properly, it can be determined even by guess and by gosh, it is deformed even under its own weight. And you can determine approximately the weight of 1 hay or wheat hay bale using the formulas above.
