What is it?

Here's a worthless fact there are only 2 different styles of knotters...John Deere has their own and every other baler uses the other style.. they have not made any changes to the design since the 1 knotter was designed roughly 100 years ago
There's you fact worth not knowing for the day ..lol

 

Oh…. yea that and maybe a few other things lol…..

 

Only because every day of the summer that it was'nt raining when I was a kid for when I was 8 yrs old till I was 16 I spend behind the bunsiness end of a New Holland baler stacking idiot cubes.. and every day 1 of those knotters would throw a fit... so I got very acquainted with those ...lol

 

Lol.. I have no doubts

 

How is it used ?

 

It turns with the twine sitting on top of the hook part when the knotter drive is tripped the little round disk sits inside of a cam gear that's what makes it trun it turns counter clockwise 360° there's another part it's called a wiper arm that wipes the knot off the bill hook after it completes the turn..
It's kinda amazing to watch.. it does it all in a spilt second .. their very touchy and the tolerances very close..parts are expensive and there a art to adjusting them and making them work correctly
