10,000 bales.... um I doubt it... A typical baler runs about 70 strokes a minute, and typical bale is 10-14 flakes. Let say an average of 12, if you have 12 strokes per bale. That works out to be 28.57 hours to make 10,000 bales with one baler, nonstop, no breaks, no malfuntions, no reloading twine.
2 balers will still make for 16-18 hour real days.
Dano as a kid, one of the local farmers would hire a crew of 4 of us, we
would usually bale 1500-2000 bales a day for 1st and 2nd cuts, less on 3rd
cutting. 2 wagons, one on the baler one making the round trip and
unloading. Things working in our favor, the elevator into the loft could be
loaded up end to end with bales and would not even slow down. I think the
old man had a 2 HP 3 phase motor running it, in the loft he had a powered
conveyor running the length of the barn. So one kid would unload the wagon
and the other would be stacking off the conveyor in the loft. But with the
elevator and conveyor it was fairly easy work and the barns opened east to
west so there was almost always a breeze, it was a sweet set up. The
Farmer's wife would run us back and forth to the field with the old JD A, and
alway have iced tea or lemonade for us and fried chicken for lunch. The
round trip was short as the fields were near the barns. Also we did not have
to do milking or any other chores, the farmers hired man did that. All we did
was bale, 10-12 hour days, good pay thou, and we were selective on who
got on the crew.
