SW Ohio | battery powered Dremel, or the old way-chain saw file.
Hanging knots has more to do with the twine arm than the knife, if I remember correctly, NH require a good whack with a hammer. |

| Hay Hud is correct. The sweep arm must have a slight rub over the bill hook as it passes, bend the sweep arm to adjust. Also check the bill hook rollers and the sweep arm brass rollers for wear, flat spots. |

Kittitas Co. Wa. State | As was stated the knives being sharp or dull has nothing to do with the knots hanging on the bill hooks,, take a hammer and "adjust" the knife arm till it just ticks the bill hooks. Use a knife sharpener or stone to get the twine knives to a razor edge. I've got a little "cheepie" electric knife sharpener that works dandy for getting a razor edge on the knives. |

Lincoln County. NC | A dull knife pulls the knot tight on the billhook rather than cutting the twine and letting the knife arm sweep the knot properly. Dull knives, retarded twine disc timing and excessive billhook cam tension all can contribute to knots hanging on the billhook. As well as a maladjusted knife arm, of course.
Edit: NH sells a knife kit with small bolts that can replace the knife on your knife arm. Grind off the rivets holding your dull knife, and bolt on a fresh edge.

Pasco WA. | I never bother with trying to sharpen the knife. New knives are just not that expensive.
A twine holder that is too loose or worn out will cause the knots to hang on the bill hooks because the tails are too long. |
