Paragraph starter
The research by Iskenderov et al. (2020) highlights the significant benefits of applying UHMWPE coatings to double-disc coulters for grain seeders. Their findings indicate that this coating reduces soil adhesion in moist conditions and enhances wear resistance in dry conditions, leading to improved operability and extended tool life. This suggests that material surface treatments are a critical consideration for optimizing the performance of agricultural machinery components operating in variable environments.
