Tianjin Power Machinery Expands Production of Baler Knotters, Wiper Arms, and Gears
Tianjin, China – Tianjin Power Machinery Co., Ltd. is ramping up production of replacement parts for square balers, specifically focusing on Knotter assemblies, wiper arms, and gear components. Operating out of our own manufacturing facility, we supply dealers and repair shops worldwide with parts that match OEM quality at a fraction of the cost.
Knotters: Breaking the Import Dependency
For years, farmers have relied on expensive imports for baler knotters. We now manufacture complete knotter assemblies right here in our factory. Our knotters are built to handle the high-speed tying cycles of modern balers, offering a reliable, budget-friendly alternative without sacrificing performance.

Wiper Arms: Built for the Field
Our wiper arms (or knife arms) are made from high-strength alloy steel. We put them through strict heat treatment to get the right balance of hardness and toughness. They are designed to guide and cut twine cleanly, working seamlessly with the knotter bill hook. If you are running high-capacity balers, these arms are built to take the wear and tear.

Gears: Precision Timing
A baler is only as good as its timing. We machine a full range of gears—spur, bevel, and complete assemblies—with tight tolerances. They mesh smoothly to reduce vibration and keep the knotter synchronized, even at maximum operating speeds.
Factory Direct
Because we control the entire process—from casting and machining to heat treatment and finishing—we keep our quality high and our prices competitive. Our parts are currently running on CLAAS, Case New Holland, AGCO Massey Ferguson, and John Deere equipment. Our catalog also includes binding assemblies, guard rings, and needles.
