When purchasing replacement gear heads, tiller attachments, or water pump attachments for brush cutters like Balwaan BX-35, Neptune, or FarmingTools.in, the most critical specification is the outer pipe diameter and internal spline teeth count.
The 28mm vs 26mm Standard
Most commercial brush cutters in India fall into two engineering standards:
- 28mm Outer Pipe × 9-Teeth (9T) Spline: Modern commercial heavy-duty standard used by FarmingTools.in, Royal Kissan, and heavy Balwaan machines. Offers highest torsional strength and maximum attachment compatibility.
- 26mm Outer Pipe × 7-Teeth (7T) Spline: Traditional standard common on older or lightweight machines. Cannot directly fit 28mm gearheads without an internal bushing and spline adapter.
Attachment Compatibility Checklist
| Attachment | 28mm × 9T Shaft | 26mm × 7T Shaft |
|---|---|---|
