L type blade:
Product features:
1. High quality steel raw materials, suitable hardness, not easy to break and deform.
2. Available for all different kinds of tilling machine.
3. The whole part has been adjusted to pass the balance test both in static and moving states.
4. Blade uses brand water-based paint in painting, which is energy saving. And drying process is added to improve the quality of the paint adhesion to blade surface.
5. Automatic shot peening surface, excellent finish and appearance.
