Baler twine knotter assembly

The baler twine knotter is the most sophisticated and critical mechanical assembly on your square baler. It is responsible for transforming loose, fast-moving twine into a perfectly formed, secure knot, binding your bales into neat, manageable packages. A well-maintained knotter is the key to a hassle-free, efficient hay season, ensuring every bale is tied reliably.

A knotter assembly consists of several precision components that must work in perfect harmony to tie a knot in milliseconds:

• Billhook: The rotating hook that forms the knot.

• Twine Knife/Knife Arm: Cuts the twine after the knot is tied.

• Tucker Fingers/Twine Disc: The “fingers” that guide the twine into the billhook to start the knot.

• Needle: Carries the lower strand of twine up through the bale to the knotter.

• Drive Gears: Transmit power from the baler’s main drive to synchronize the knotter’s movement.

Knotter assemblies are available as direct OEM replacements (John Deere, New Holland, Case IH) or high-quality aftermarket units from brands like A&I Products, Bepco, and TISCO. You can also purchase individual components, like a new twine arm, billhook, or knife, for targeted repairs. For a comprehensive solution, rebuild kits are also available, containing the high-wear parts needed to restore your original knotter to like-new condition. For a complete overhaul, you can send your existing knotters to a professional service for rebuilding.

For baling efficiency, knot reliability, and avoiding downtime during critical haying windows, a quality knotter assembly or rebuild kit is an essential investment.
