I’ve learned its easier if you just pay attention to how much net wrap you have left and when you can start to see the tube that the net is wrapped on, stop the machine, unspool 2-3 feet of net off the old roll, cut it with a knife and just tie your new net roll onto the old 2-3 feet of net that is still in the machine.

probably the only drawback with the 1250 .........the net would sometimes act up on you ...........otherwise a very underrated baler ................
