Description
These robust Category 3/3 lower link balls deliver maximum strength for connecting the largest agricultural implements to high-horsepower tractors. With precise 37.5mm inner diameter and 63.5mm outer diameter specifications, this matched pair provides the heavy-duty connection points required for extreme tillage operations, ensuring safe and reliable implement control when operating equipment that pushes the limits of modern agricultural machinery.
Key Features
- Full Category 3/3 rating for maximum load capacity
- Precision dimensions: 37.5mm ID x 63.5mm OD
- Forged from premium alloy steel for extreme strength
- Compatible with CAT3 to CAT2 conversion bush (43155)
- Hardened wear surface extends service life
Applications
Essential for the largest agricultural tractors operating heavy-duty implements in commercial farming and earthmoving applications. These Category 3/3 balls are designed for tractors exceeding 150 horsepower commonly used with massive disc rippers, heavy-duty subsoilers, large offset disc harrows, and industrial-scale land levelers. The full Category 3 specification is crucial for custom operators and large-scale farming operations where implements must withstand continuous heavy use in challenging soil conditions, from breaking new ground to deep tillage in compacted soils.
Quality and Technical Benefits
Manufactured from specially selected alloy steel that provides superior strength compared to standard carbon steel components. The forging process creates optimal grain flow patterns that maximize resistance to the extreme tension and shear forces encountered during heavy tillage operations. Advanced heat treatment produces a case-hardened exterior reaching 58-62 HRC while maintaining a tough, ductile core that prevents catastrophic brittle failure. The 63.5mm ball diameter distributes loads across maximum surface area, reducing stress concentrations that cause premature wear in inferior components.
Installation and Compatibility Notes
Professional installation recommended due to the extreme forces these components must withstand. Ensure lower link arms are rated for Category 3 applications before installing these balls. The 37.5mm inner diameter requires Category 3 lower link arms with matching specifications. For versatility, these balls accept conversion bush 43155 to accommodate Category 2 implements when needed. Always replace balls in pairs and inspect regularly for any signs of wear, cracking, or deformation. Apply high-pressure grease to ball surfaces before implement attachment. These safety-critical components should be replaced immediately if any damage is detected, as failure during operation could result in serious equipment damage or injury.
