Tianjin Power Machinery Unveils Complete Knotter Assembly System for Balers, Delivering Superior Durability & Global Market Success
[Tianjin, China, November 17th, 2025] – Tianjin Power Machinery Co., Ltd. (TPM), a leading agricultural machinery parts manufacturer, today announced the official launch of its specialized Knotter product – Knotter 1120.23.23.00.03 Welger, a complete functional assembly engineered for exceptional durability, precision fit, and affordability. As a dedicated spare part for Welger AP balers, this product has already gained wide recognition across Europe, Asia, and Latin America, helping agricultural users reduce equipment downtime and significantly lower maintenance costs.
Technology & Advantages
1. Advanced Manufacturing Ensures Premium Quality
Knotter 1120.23.23.00.03 Welger is manufactured using high-grade alloy steel and advanced CNC machining, ensuring dimensional accuracy within ±0.01 mm – a critical standard for matching the precision requirements of Welger AP balers. All friction and engagement surfaces undergo high-frequency quenching and black oxide coating to enhance surface hardness (HRC 58–64) and corrosion resistance, increasing component life by more than 2.3 times compared to industry-standard parts for Welger replacement.
2. Optimized Structure for Welger AP Series Compatibility
As a fully functional unit, Knotter 1120.23.23.00.03 Welger features a integrated body on which all knot parts are installed with premium fastening elements and standardized connections to other units of Welger bale formers. The product is precisely modeled to Welger OEM specifications using 3D reverse engineering, with strict alignment to OEM numbers including 1105.23.00.00, 1120.23.23.00, and 1120.23.23.00.03.
It is fully compatible with a full range of Welger Baler models, including:
Welger AP41, AP42, AP45, AP52, AP53, AP61
Every unit undergoes 100% assembly testing before shipment to ensure seamless integration with existing Welger bale former systems.
3. Cost-Effective & Plug-and-Play Design
Compared to original Welger OEM components, TPM’s Knotter 1120.23.23.00.03 maintains over 95% mechanical equivalence at 60% of the cost, enabling users to extend the service life of their Welger AP balers without compromising performance. As a dedicated spare part for repair scenarios, its pre-lubricated packaging and calibrated fittings reduce installation time by up to 50%, minimizing downtime during maintenance.
Global Market Feedback
Knotter 1120.23.23.00.03 Welger has gained significant popularity in key agricultural markets including Poland, Ukraine, India, Brazil, and Turkey – regions with high usage of Welger AP balers – with initial monthly shipment volumes exceeding 7,000 units. Customer reports show a 35% reduction in knotting failures and an average 20% increase in daily baling productivity after replacing worn or damaged original parts with TPM’s Knotter 1120.23.23.00.03.
Commitment to Agricultural Reliability
“Knotter components may seem small, but they are mission-critical to efficient forage harvesting, especially for users relying on Welger AP balers,” said AWEN, Director of TPM Agricultural Machinery Division. “We recognize that timely access to high-quality, affordable spare parts is vital for farmers. That’s why we focused on developing this specialized knotter – to address the repair and maintenance needs of Welger users worldwide. We will continue to invest in materials research, robotic quality control, and logistics optimization to better serve our partners.”
