MF-12 knotter spring

[Todd Dixon]

A compression type spring on one side broke. I need more information about it. It keeps tension on the arm below the fingers and moves the twine sideways. It is about an inch long and the end the coil is turned 90 degrees and goes through a hole in the tensioning nut. What would you call it and where do I get one?

I presume you are meaning the spring that returns the tucker finger drive arms back to position. Home Depot, Lowes, Tractor Supply, Ace Hardware, etc, usually has boxes with various spring lengths and tension which do this job. Heck, I even used a rubber tiedown strap temporarily to finish a field.
