West Central Wisconsin | MF 2150 baler. Baling stalks. Baled 100 bales with little issue. Now outside knotter will not tie a bale. Actually it won't release the knots off of the bill hook. I have played with twine tension, bill hook spring tension, and sweep arm clearance with no luck. I even retimed the baler. The knotters were.off one tooth. I am at wits end. I put a new bill hook in and a new sweep arm. The first two pictures are what I think is causing the issues. The bill hook does not reset. The third picture is how it should look. Just can not figure out the issue.

Klamath Falls, OR | is your knife arm wiping the bill hook hard enough? that is where I would start. get good tight contact |

West Central Wisconsin | Yes. It is rubbing very hard. |

| Sometimes they can be fussy with the bill hook spring tension. I would go tighter than the rest especially if the piece the hill hook rides on is wearing out... I have had to replace that part as well. Check the wear on it where the bill hook rides compared to the others i think there is suposed to be a little groove there if that wears smooth the bill hook will pop out like your pics. One time the pin that holds the bill hook in the drive gear broke and fell out that acted similar to your situation took me a few knots to figure that one out. I've had a knotter frame get tweaked and give all sorts of trouble too. |

Hemlock, Mich | I had some of the same issues with a small square.... Put a new twine knife on and it works. Some times only a few hundred bales... |

mercer county, il | +1 when our Hesston starts having issues usually the billhook cam is worn, and instead of closing just runs out and stays there. once the groove/edge is worn off they do not like to stay in, more billhook tension can help, but ca also lead to other issues as well. |

SE Idaho | How is the trigger on the other side? I have seen grooves warn into them that will make it hard for the knot to slide off. Also how is the cam follower roller on the end of the knife arm?

Central Kansas | No one has mentioned it yet. Be sure to check your lower twine tension. It will cause similar problems. |
|
| |
|
Southeast South Dakota | My 7433 will do that once in a while. Like the above poster said be certain your lower twine tension is correct. Other than that the groove the roller rides in could be worn but my money is on the tension. |

| Not unusual for them to pop out when lifting knotter. My money is on lower twine tension. I've fought that in stalks a lot. Maize Corp has some guides that help with that problem. |

Helenville,WI | Had a similar issue that we thought had to be a wiper arm adjustment, but was actually twine getting pinched on the side of a roller on the lower twine tensioner. Green crap had wadded up on the roller, and the twine would slide off and get wedged on the side. Definitely an area to eyeball. |

Northern CA | I would also think about emptying the bale chamber, looking for buildup and interference with the hay dogs or a broken hay dog spring. |

| Is it having trouble stripping off the first or second knot? First would point to lower twine tension, slacker arm or twine finger.
Second may point to billhook tension being too high. It's not entirely unusual to have the tails hang until the bale progression drags them out, but the knot should at least be complete.
Also take a look at the love that drives the stripper arm and make sure it doesn't have too much wear.
As far as the billhook popping out of the track, I agree with another that might be from lifting the head. Otherwise I don't think it would explain the knots not stripping. |

thumb of mi | When ours did that it was twine roller junk on lower tension arm. Junk wound up on it.
As far as the timing goes they so,etimes run them a tooth off so the plunger holds the flake up longer I know ours was like 3 teeth off and was advised to leave it. |

| Hi There,
I am new to forums so not sure if replying to your post is the right thing to do or if I should create a new post? Anyway I am a farmer in Tasmania, Australia and am having knotter problems with a Hesston baler too. Mine is badged as Massey Ferguson (MF) 185 Series 2. Its a 3x3 Square Baler with double knotters that I am having ongoing trouble with. The last couple of seasons the outside knots on 1 and 4 have been weak (let go on the second knot (one that starts the bale) when the bale hits the ground) or drops this second knot (1 in ~ 40 bales) when bailing barley straw or very dry and springy grass hay. The knots have held ok when bailing Lucerne or Clover or Greener hay with occasional miss ties. I have managed to work around this by bailing with less pressure in the chamber but have had lighter than ideal bales because of it. I have changed to a new thicker twine this season, with greater knotting strength (to try and overcome the problem), but I and am now having more trouble than ever before. I have gone through the manual of the baler and adjusted as much of the knotter systems as I understand to within specs. I have the twine tension set to 70N on the upper Twine tensioner and 80N on the Lower Twine (Increased from 70N as recommended by the manual as I was getting a short tail on the second knot). I have replaced twine rollers and ensured that twine routing is correct and not restricted anywhere.
I have installed new twine knives and checked the twine finger adjustment. The stripper arm is gently rubbing on the bottom of the billhook. I have taken some ultra slow-motion video footage of Knotter 4 of the baler tieing when the baler is operating at 350 PTO RPM so you can see what is happening. I am unsure how to attach this footage to the post as it appears I can only attach files under 2MB. I could email or text this video to anyone who is interested in helping. The first knot (finishing the bale) appears to be tieing perfectly and swept off the billhook but the second knot (starting the new bale) is constantly sub standard and ugly and regularly hangs on / hasn't fully being tied by the billhook . Both inside knotters 2 and 3 are tieing both first and second knots nicely with no issues. There are very few square balers is use in Tasmania as round bales are the norm and I haven't been able to find anyone who can shed any more light on my problems. I would appreciate any help or advice than can be offered. We are currently in the middle of harvest but have been rained out so have some time on my hands to try and rectify the problem (s).
Thanks in advance
Kind Regards
David

Northern CA | What’s your email? I would like to see a video and some pictures. First I was thinking of thicker twine. What twine strength are you running now? By going to heavier twine, you might need to run lighter settings on some parts of the tying system. How many bales are on the baler? |
