4 x5 bales twine wrapped putting the max number of wraps on I can usually do 15 or so an hour sometimes more, my bigger field I can do better as I don't spend as much time turning with the longer windrows. This is in average first cutting. Baling with a NH 450 utility baler. I usually run about 4 mph as most of my ground is a little rough and I try to be easy on the equipment and me.
