I've got an old NH Super 77 baler with PTO drive.I've gone through the whole machine, adjusted knotters, clearances, etc. I can hand pitch all the loose straw and broken bales that I want and it doesn't have any problem. But, out in the field with heavy straw the needles seem to catch the loose straw at the end of the bale when they come in to tie.Then either the knotter chain breaks or the needles snap. I've got new needles, but am afraid to try it till I know its fixed. Needles ain't cheap!

check timeing and see if plunger knife is sharp.needels have ben broken by dull knives if it right needel standing at back of the baler it could be your plunger knife.

some NH pto balers have problem with the clutch that mounted that front of the baler. i had a 278 that i traded to a friend. he removed the clutch assembly and found that 3 0f the 4 holes were missing in the ratch assembly. trying disassmeblying the pto clutch, could solve yor problem.

Dave:

If you need another new needle, I have one to dispose of from a 1951 NH 77.

Our old baler has been put in a museum and we do not need the spare needle we had.

Send me an e-mail if you are interested.

You need to check the knotter timeing, sounds as if its off a bit. There are timeing marks up at the plunger crank and back at the knotter drive. When the crank marks line up the knotter marks should be also.....

Just a thought. Are you sure they aren't hitting the plunger? What about the hay dogs, do they hold the hay forward?

THERE IS ALSO NEEDLE TIMING TO CONSIDER THAT ISWHEN THE NEEDLES ARE JUST STARTING TO ENTER THE BALE CHAMBER THE TIPS OF THE PLUNGER SHOULD BE BETWEEN 1/4 TO 1/2 INCH PAST THE NEEDLES IF NOT YOU NEED TO PULL THE KNOTTER MAIN DRIVE CHAIN AND ADJUST TO THOSE SPECS ALSO CHECK THE CROSS FEED TIMING AT SAME TIME

This baler isn't like the typical newer machine. There doesn't seem to be much timing as far as the tying function is concerned. When the bale reaches the correct length, a latch comes in and holds the plunger in the fully compressed position where it stops and waits for the tie to be made. The needles pass through slots in the plunger while the plunger is at a dead stop. Once the tie is made, the latch is released allowing the plunger to continue its stroke. Kinda strange but it works (sort of...)I have heard these were tough old machines in their day which was the mid '50s.

So, how does the plunger disconnect from the flywheel/drivetrain when the 'latch' grabs it? Not familiar with that model of baler, but doesn't sound like it's right? There is a little latch that prevents the plunger from breaking the needles on most other models of NH balers, but it's bad if that latch is actually used. :)

Paul,
It has a telescoping connecting rod from the plunger to the crank. When the plunger latches forward to tie, another spring loaded latch on the connecting rod releases allowing the rod to telescope in and out as the drive train continues running. When the tie is complete, the plunger latch releases, as rod comes forward the rod latch locks and pulls the plunger back & forth until the next tie cycle.This baler also has the old external wad board on a big arm that goes up and down into the chamber like the old stationary hay presses. I got this baler with the intent of it being a "usable antique". I'd use it at our local steam show to clean up the straw pile while threshing and still be able to put up a few hundred bales at home on our small farm. So, I'm not necessarily nuts or that cheap to use such an old beast, I just like some of this old technology. Its just tough finding answers to problems sometimes cuz nobody uses it anymore...
Thanks to all for their help.
