New Holland Round Baler or Square Baler: Which Binding System?

A New Holland round baler — like the BR 7070 — forms cylindrical bales by rolling the crop inside a compression chamber. Once the bale is formed, it is bound by a mechanism that wraps synthetic netting or plastic film around the bale without using knotters. The binding system on a round baler consists of a net/film dispenser, a wrapping arm, and a cutting blade. There are no twine knotters involved. In contrast, a New Holland square baler (Big Baller series BB 960, BB 9070, BB 9080, BB 9090) forms rectangular bales using a piston and ties them by passing twine around each bale with mechanical knotters: this complex system includes needles, knotters (duck bill, discs, levers), twine knives, and control cams. The technical features of the binding system differ significantly between the two machine types. TMC Bejenne offers binding parts for both: Big Baller (BB 960 to BB 9090) and Round Baler (BR 7070).

How Does the Binding System on a New Holland Agricultural Baler Work?

On a New Holland Big Baller, the binding cycle starts automatically when the bale reaches the programmed length, detected by a mechanical or electronic counter. Binding needles descend from the top of the pressing channel and pass through the bale to deliver the twine to the knotters. Each knotter consists of a rotating duck bill that grabs the two strands of twine (the one brought by the needle and the one waiting from the previous cycle), loops them, and cuts the feed strand with a binding knife. The quality of the knot relies directly on the condition of the duck bill, twine tension, needle alignment, and wear on the control cams. Models BB 9070, BB 9080, and BB 9090 use a system with 6 knotters (two rows of three) to bind large-section bales at high speed. The pick-up upstream, responsible for crop gathering, affects the consistency of filling the channel and thus the uniformity of binding — a worn or poorly adjusted pick-up produces irregular bales that overly stress the binding system.

Binding Problems on a New Holland Baler: Common Malfunctions and Diagnosis

• Unbound bale: the needle does not drop into position (worn trigger cam or mechanical blockage) or the duck bill fails to grab the twine (worn, misadjusted, or clogged with compressed dry hay)
• Twine breaks: excessive tension on the tensioner, poor-quality twine, or needle notch damaged and cutting the twine as it descends
• Slipping knot or opening bale: worn duck bill (the helix no longer twists the loop properly), worn binding disc, or weakened return spring
• Double knot or knotter jam: twine or plant residue stuck in the duck bill, must be cleaned thoroughly before adjustments
• Needle catching the bale: needle deformed by impact or misaligned relative to the pressing channel — check alignment after any piston replacement
• Contact 05 86 24 00 26 to identify the faulty part for your New Holland BB model

New Holland Big Baller BB 960 and BB 9000: Binding Parts in Stock at TMC Bejenne

The New Holland BB 960 is one of the most common square balers on farms and cooperatives in France. Its 4 or 6 knotter binding chain is robust but gradually wears with use: duck bills, twine knives, and trigger cams require regular checks at the start of each season. The BB 9070, BB 9080, and BB 9090 are the following high-capacity models, with larger bale sections and faster binding cycles, placing greater demand on the mechanisms. For these models, replacing a complete used New Holland knotter remains the fastest solution in case of baler failure, avoiding wait times for new parts. The feeder and packer before the compression channel must also be in good condition to ensure consistent filling and proper binding operation.
