Wear of cultivator coulters reinforced with cemented-carbide plates and hardfacing

Three constructional solutions of coulters used in cultivators were assessed with regard to their wear resistance in soil. The coulters were installed on a four-beam cultivator used for cultivation of loamy-sandy soils with humidity typical for the summer season. It was found that the amount of thickness reduction of the coulters in the areas with cemented-carbide plates and padding welds was lower than that in the base-material areas. It was...
