For a few years growing up, we had 3 International balers (2 #56, 1 #57). They had engines (4 cylinder gas) on them and we had a Harobed (New Holland automatic bale wagon) to pick the bales up. We had irrigated alfalfa that yielded 8-10 tons per acre for the year, usually 3 cuttings, once in a long while we would get a 4th. We would usually cut about what we could bale in a day, then cut more the next day and so on. If we did not get any rain, we were able to keep up with the hay that was ready and not have hay on the ground too long. One time, the perfect timing hit us and some rain delayed baling a few days and we had about 150 acres down, ready to bale. We baled early morning with some dew on to keep the leaves intact, but not too much (otherwise bales would mold)... It was dry enough (just a little dew after it dried out from rain) to bale and about the time it was getting too dry, we had a little lite rain shower so we kept baling, this went on all day (we started between 4-5am) and baled past dark that night. We baled all that we had ready and then the next day I had to stack it. The harobed could pick up 63 bales at a time (8 on a layer, 8 layers high with one less bale on layer that had tie in it). I don't recall how many bales, but it was a long day of baling and we had to stop several times to service each baler (fuel, wire, grease)... followed by long day of stacking.
Good memories for sure... except we had all open station tractors and equipment so it was miserable from that aspect..
