My 62T has been working great, not missing a knot. Now it has started breaking shear bolts when it gets ready to send the needles up to tie the next knot. It breaks a shear bolt about every 10 bales right now. What is going on? |

The first place I would check is the brake on the knotter shaft [may be on the needle frame]can't recall. If brake is loose, needles can move enough to allow the saftey dog to move in front of the plunger and cause the bolt to shear. #2 check the timing of the needles to the plunger, at the start of the tieing cycle the needles should enter the plunger slots 0.5 to 1.5 inches behind the face of the plunger. You will have to jump the knotter drive chain one tooth at a time on the drive sprocket. The Operators manual explains this and has good photos. Much better than I can here. |

Our New Holland did that once too. The spring on the safety was broke and there was just enough play in the linkage that every once in a while it would catch the plunger and take a shearpin out. |
