The research of influence by application of welded ploughshares on the efficiency of tractor's work during ploughing

Standard and welded ploughshares were tested. The standard ploughshares are made of steel 50Mn7. The welded ploughshares are made by applying C-Cr-Co-Ni-Si additional material on the same steel. The research was carried out by using two tractors with two four-furrow plough of the same power in a total of 360 working hours, and a total of 180 hours of ploughing with each ploughshare. The average achieved effect of ploughing with standard ploughshares was 0, 85 ha/h with fuel consumption of 29, 70 l/ha. With welded ploughshares was achieved the average effect of 0, 90 ha/h with average fuel consumption of 28, 30 l/ha. Based on these preliminary results of research it was concluded that the welding layer which containing Cr carbides can be affected to increase the efficiency of ploughing.
