haveing trouble with right side not tieing but left is fine seams that string isnt staying in knotter tight enough is the nut with spring below knotter to tighten this to correct it
 
this will sound trite, but get a new holland baler manual, any NH manual. There is a troubleshooting section, in all of them, with pictures of failed knots, and what causes them. More helpful than any guess I could give you.
 
This will not be in any of the manuals but see if there is any up-down movement in the plunger, if there is you need to replace the slides as that will make it so it will not grab the twine correctly. You may also have knotter problems but if that plunger has movement you can work till you are blue in the face and still not get it to tie. Found this out back in the mid 70's. would not tie and everything in knotters was redid, finly got a different repairman, took one look at baler and said the slides were the problem, Dad said I don't believe you but change them anyway, did and without touching the knotters did not miss anouther bale.
 
My 68 was doing the same thing, turned out that the bolt/screw holding the twine disc had been replaced with one that was not perfectly round- headed like the original. The knot would tie but would sometimes catch on the bolt head and that would pull the knot apart. The twine disc is below the knotter and is bolted to the bale chamber. It took forever to figure it out. HTH
 
'nother thing..Sometimes the 'finger' that holds the twine into the disk gets a groove in it after millions of bales.that groove prevents the finger from holding the twine tight.You cant see it,have to loosen the tention nut and swing the finfer free to inspect.This groove is subtle,but you can feel it even if you cant see it.
 
If those things check out,check your knife clearance.Be sure the knife is sharp.If it isn't it can be pulling the twine out when the plunger pulls back.
 
Oops, What I was calling the twine disc is actually called the twine fingers. But anyway, it is a semi circular disc lookin thing beneath the knotter and is bolted to the top of the bale chamber. Make sure that bolt is a round headed screw and does not have anything that can catch the twine.
 
found problem the twine holder tension spring was broke not allowing string to stay put after baling all day the knotter drive chain broke , This machine has set out for several years chians were very rusty when I bought it oiled and greased everything seamed to start working but you know it can't be that easy , any how now need to put back in time going to put new chain on no repair because it will happen agin. can someone tll me how to time it
 
Here is how you time the knotters:
1. Remove the knotter drive chain
2.Turn flywheel counter-clockwise until the crank arm is straight up and between the timing marks on the bale chamber.
3. Make certain knotter drive pawl is resting against the knotter stop. Remove backlash by pulling upward on the needle yoke at the point where it attaches to the knotter arm.
4. Turn knotter clutch gear until the timing marks of the knotter clutch and the knotter clutch disc are directly opposite each other.
5. Install the knotter drive chain and tighten the chain keeping the timings marks aligned.
6. Turn over by hand with the knotter engaged to check the needle timing. Needles should enter the bale chamber when the plunger points have passed the needle points by 1/4"-3/4"
