I have a NH super 66 square baler. As the bales are formed the bale and twine closest to the pick-up side always becomes progressively looser with each bale. About every tenth bale it results in the bale bending open like an accordian and falling apart. The knotters seem to tie alright with the same string length. Any suggestions?

They gave you some good answers but on the 66 you do not have tine fingers you have what they call a wadboard. To set it you have to jump the chain that drives it on the sprocket so when it all the way in the chamber it is about 3and one half inches from the outside. Another thing is your plunger knife and your stationary knife they hAVE TO BE SHARP and properly adjusted or you will have banana shaped bales.If you lived here close to me in east texas I would fix it for you and like they said you need to replace all broken pickup teeth and make your windrows a little larger. Please get you a manual from New Holland and study it so you can make adjustments on the baler.

Hay dogs are located on the top and bottom of the bale chamber in the knotter section and are spring loaded. When the plunger pushes the hay torwards the back, these dogs are spring loaded inwards to keep the hay from springing back torwards the front when the plunger returns. Hope that helps.

The wadboard is likely out of adjustment

Burrhead and Tim, thank you for the reply. If I understand your answer correctly, Could the lack of 3/4 of the pick-up tines on the outer side of the pickup head be the problem? (as it is I can only collect hay on the inner part of the baler pick -up head because of the lack of outer tines) If I simply replaced them would that likely solve the problem? Also, what are 'hay dogs'? Thanks again, Jon

Yes the pick up fingers will cause the same problem.
It slipped my feeble mind to ask about them.

The pickup fingers and windrow should supply a good steady even flow to the feeder tines.

The hay dogs are in the front top end of the bale chamber just below the knotters. They are for direction control of the hay as the plunger packs it into the new bale.

They keep the hay tight as the plunger starts another stroke. The plunger pushes the hay back and the hay dogs raise up, then springs pull the dogs back down to keep the hay tight with the plunger pressure gone.

I attached a copy of the mis-shaped bales instructions from the NH book for you.

Thank you for the help, I'll get an old manual and give it a whirl. - Have to wait a while however, as I live in northern Maine and there is about 20 inches of snow on the ground!

LMAO. Yeah I don't think you can adjust that 66 to bale snow.

Could a non-operating hay dog also be the problem? Had that happen on a JD 336 once.

Yep the hay dogs can cause one sided bales but not to the extent he's described.

On a NH one of the most important part that the hay dog does is keep the twine free after the tie stroke as the plunger starts going forwards again so the bill hooks don't get snatched tight too quick, which in turn lets the bill hook spit the twine out after it knots.

If a hay dog don't work right it can either cause the twine to hang in the bill hook, or it can cause the bill hook to miss the twine when it spins to tie knot.
