All depends on hay and weather conditions. I personally bale mostly grass hay, and if the humidity is low enough you can start rolling before lunchtime here and go until just past dark. You can extend those times quite a bit if you're baling high moisture and wrapping it. In thick hay it isn't hard to get 30+ rolls per hour running 6mph or so. My tractor has radials and the roller has floaters on it, but much past 6mph and it gets pretty rough if you hit a groundhog hole.This is also a little off topic, so forgive me, but I see folks mention they bale 250 bales or more, so I'm assuming baling during the day and not baling Alfalfa hay. Out West I bale at night (Alfalfa) so it's cooler and have less leaf loss compared to in the heat of the day and watching the leaves just pile up behind the baler when I dump. Even at speeds of 5mph which is easy on me and machine I can't get 250 bales before I have to shut down(to dry). How is everyone hitting that #. I've used various balers and currently run a big Kubota baler. Regardless of brand I never hit high numbers. Been considering adding a 2nd baler to double production. So what's the secret?? Assuming just baling grass so not as touchy as Alfalfa?? Again just guessing!
