I am one of those that say, "do you have a manual" because quite often (70%) or more of the problems here are addressed in a "manual".
More importantly, if you have a manual, we can talk intelligently to one another. "Yes, I have tried that per page...." and it makes it much easier for us to understand your problem.
Your problem yesterday with the twine falling out of a needle, sounds like you have mis-threaded the twine and missed a twine guide of some sort or there is not enough tension as the twine comes out of the twine box. If it were a JD baler, there is a decal to show how to thread the twine and it is also in the "manual". Sorry I cannot be of more help with NH.
