Engineered for Efficiency:
The Next Generation of He‑Va Stealth Wear Components
After reviewing the performance of the original R2749, we identified two main issues: inefficient wear on the side plates and erosion on the underside of the leg. That feedback proved invaluable, and the improvements that followed have made a significant difference in durability and overall machine performance.
One of the biggest steps forward has been the introduction of full tungsten protection across the point, shin, and wings. With a 271 mm working height of carbide coverage and a heavy‑duty tungsten‑shaped nose tile, the new setup offers far greater resilience in abrasive soils. The unique profiled tungsten tiles on the shin—16 mm wide to match the full width of the base leg—now provides complete protection, with the raised central ridge providing a 7mm leading edge to help cut through ground and reduce soil burst on the surface, reducing the likelihood for unwanted blackgrass seed etc to work up the profile and germinate in the topsoil tilth, as seen on flat profile tiles. while the revised nose profile improves ground penetration and reduces underside wear.
The modular point and side‑plate design, developed directly from user feedback that the R2749 was too bulky and wore inefficiently, is noticeably more streamlined. The overall body width has been reduced from 32.0 mm to 24.0 mm, making the assembly cleaner through the soil and more efficient in operation. Complemented with the independent slip-on wear plate (13337) has completely resolved the side‑wear issue.
Rear tungsten wing tips have also played a crucial role in maintaining wing shape and lift height. The addition of the rear wing tiles has prevented wear at the fixing points entirely, making removal just as easy as installation. More importantly, the wings have retained their geometry across more than 300 acres of work. This has ensured consistent lift and soil movement—critical for effective cultivation. By comparison, many tungsten‑edged wings wear from the leading edge toward the rear outer edge, reducing lift and potentially impacting root development. The updated design avoids this issue completely.
For He‑Va Stealth users, the expanded range of compatible components has been a major advantage. The additional bearing kit for post‑2020 machines (13248), the extra leg option (13339), and the updated point and side‑plate set (R3749 & 13337) now offer a flexible, comprehensive solution for a wide variety of setups.
These updates show a clear commitment to continuous improvement and to listening to real‑world operator feedback. The result is a stronger, more reliable, and more adaptable product range that delivers genuine benefits in the field.
