Mountain West | On a JD 347 one knotter is leaving an extremely short tail on the knot, to the point where it occasionally comes untied. I've varied the adjustments from both sides of book recommendations on the twine discs, knife arm, tucker fingers, needles, twine tension, billhook tongue pressure, and switched between billhook types. I've tried light plastic, heavy plastic, and sisal. It works best with heavy sisal, but I want to use light plastic, which gives me the most problems. I would appreciate any ideas. |

Kittitas Co. Wa. State | weak (broke) hay dog spring can't get the dog back down into the chamber fast enough or could be worn down and needs replacing. . |

Alberta, Canada | So is it making the tail too short like in the picture? At times it would just be barely enough sticking out on the one knotter. That happend one time to me, but I'd have to check my book to see what I did to fix it.

N.C. Oregon | You are asking it to tie a smaller diameter twine. Adjust accordingly. |

SW Ohio | Don't have a lot of time today, Have you checked the position of the twine knife? sounds like it may be bent and cutting too close to the bill hook, or twine knife arm is loose in the pivot. |

Texas | Agreed. Check the dog spring. Bet it is broken. |

Mountain West | Larry in AB, the knot tail is even shorter than the one in your picture. There is barely enough tail to hold a knot.
The hay dogs and springs are good. The dimpled retainers could be better. I'll probably replace them soon.
The twine knife is straight and sharp. I put new bushings in the knife arm. The throat is grooved somewhat, so I may replace the arm next. |

West Texas | Just start replacing parts, you'll find the problem on the last part you buy. |

| Is the knot loose right after it is tied when there is still slack in the strings? If so, could be the billhook is not holding enough tension on the string as the wiper arm wipes the string off. The twine slips out of the billhook to easily and leaves a loose knot. As the bale exits the bale chamber and the bale springs out, the slack in the knot is taken up and leaves very little tail. This might also explain why the heavy sisal works best. |

Lincoln County. NC | Set the twine disc timing on the early end of the spec and the knife arm clearance on the thin side. NH looks for 3/8" to 1/2" of knife arm/ billhook clearance at the end of the knifearm stroke, try the lower end of whatever Deere wants. The actual twine knife being bent towards the billhook is a very good thing to check for. |

Kittitas Co. Wa. State | (JD probably calls it something different) Can't tell by looking, have to drive the roll pin out, if you get more than 1 piece roll pin that's the problem. Had that happen once, would lose a knot as wasn't pulled tight enough. Very random bad tie knot, #2 twine slipping out. . |

Mountain West | The knot is a little loose coming off the billhook. I've tried two billhooks (used) and set the pressure at the high end, but I'll double check. Thanks. |

| I've got a Ford with similar problem right now. Still haven't finished working on it... but when I do it'll be a matter of retiming the twine disc and then possibly rebending the stripper arm to get the correct knife relationship as Rick suggested. I've been through everything else. It's either the twin disc timing or the knife/billhook relationship assuming that you have the twine tension reasonably close...

| Brett, I noticed this year both of my knots are loose like this using plastic twine. Without looking at my manual, I see what you said, but what do I adjust to fix this. I suppose if I was looking at my manual it would be obvious.
TIA |
