Baler capacity

[JakobTischler]

I'm trying to calculate the correct baler capacity for the Ursus baler. From the Ursus website:

Weight of straw bale, 100 - 170 kg, weight of hay bale, 150 - 270 kg

So if my calculations are correct: wheat_windrow = 135 kg, density = 0.04 kg/l -> capacity = 135 / 0.04 = 3375 barley_windrow = 135 kg, density = 0.036 kg/l -> capacity = 135 / 0.036 = 3750 dryGrass_windrow = 210 kg, density = 0.05 kg/l -> capacity = 210 / 0.05 = 4200 -> average capacity = 3775

Would I use the average capacity in this case, or rather use the capacity multipliers (capacity:3375 -> wheat_windrow:1, barley_windrow: 1.11 / dryGrass_windrow: 1.24)?

dryGrass_windrow multiplier = 1.25 base capacity = 3700 (a barley straw bale would be lighter than a wheat one)

PS : there is no "exact" science. This is just "knowledge" and "guess" figures. PPS : But your figures are "realistic" too ;)

Ok, so I take the "lightest" one as the base capacity (3750, with multiplier 1 for barley_windrow) and adapt the multipliers for the other fillTypes accordingly, correct?

That would mean: wheat_windrow multiplier = 0.9 dryGrass_windrow multiplier = 1.12

[quadural]

no : keep 1 for wheat and barley (same capacity - same compressibility - the barley straw is just a little lighter)

capacity = 3700 to get a "fair" weight of 150kgs for a wheat straw bale then, barley would be : 133kgs and apply a 1.25 multiplier to the hay => 230kgs

always start from the wheat weight you want (in my case, I would bet on something near 150kgs in our case)

Alright, thanks.
