Hi, I have a MF 124 baler that keeps breaking the string. We turned the baler by hand and I watched the needle come up with the string, the knotter grabbed and tied the string. When the needle proceeded to descend it went about 6 inches from the knotter and the string in the eye of the needle broke almost like someone cut it with a knife. I checked and found no rough edgesin the eye. The eye seemed smooth. This happens with new string. The string doesn't appear to be getting hung up on anything that i can tell. Any suggestions? Thanks.
