NH 273 baler problems

Problem 2:
strings are not tight and bale wants to bow out.
(got the tension almost as tight as it will go)

Makes a pretty good bale with good clean bermuda hay but baling rough stuff has a real problem

Any help would be greatly appreciated!!

Near the baler discharge point there will usually be a couple of handscrews and heavy springs.. these control an adjustable constriction in the exit path from the bale chamber.. the tighter the constriction, the more dense the bales.

Another poster mentioned Sisal vs. Poly twine.

I went back to Sisal from poly myself. Reduced knotter misses dramatically... My baler has spent its whole life on Sisal.. and it's 'worn in' to it.... But that wasn't the main reason...

I got tired of picking up poly twine every time I turned around !

If you aren't really diligent in your twine 'habits' it gets everywhere... and it's a mess.

Knotter problems:
changed the knive arm out and things seemed to get better...the knot still hangs on the bill hook quite frequently...we've adjusted the bill hook tension, tried filing the end, and re-alignmend the needles...next step is to change out the bill hook (it doesn't seem to be as smooth as the outside one. Any tips on this change out would be appreciated.

Bannana Bales:
Think part of the problem is the bill hook hanging problem...when it hangs it streches the string making it more loose. Also wind row and material seems to make a difference.

Things are getting better....

thanks again,

The other main cause of bananas is under-feeding the bale chamber...i.e. not getting enough material in to fill the chamber completely.

May be a windrow/speed issue.. or your packer fork stroke may need to be adjusted for the rougher material.

You say you have "the tension up all the way"...
What about your bale density adjustment ?

Do you have that cranked up for this rougher material ?

Your "finished" twine tension will be determined by the combination of initial twine tension at the knotter and how much the bale wants to expand as it leaves the bailing chute. If that 'rough' material doesn't want to expand... loose twine.

As far as the "knot hanging on the bill hook.." sounds like the knotter is missing the pick-up of the twine from the needle ?? (shot in dark)

Check your needle adjustments to make sure the twine is being 'presented' to the knotter properly.

If the outside knotter is working right, make the inside needle match it's positioning relative to the knotter and things may get better.

Will be trying to adjust again tonight to see if we can get things right.

Dan...I've got a manual, ordered from NH website. I'm just new to this and figured you guys could point me in a better direction.

bbott...didn't know about the bale density adjustment, I'll check the manual for instructions on this.
I'll check the needles too.

Any tips on watching knotter system work??
i.e. have someone feed it manually right before it ties or work it manually by cranking the fly wheel??

this has been a big help guys thanks!!

Pay particular attention to how the 2 neeedles are lined up... if the left hand knotter is tying correctly, see if the right hand needle isn't adjusted somewhat differently.

Having a manual will be a great help.
