Inhoud: Investigation of the various ploghshare materials wear on the five bottom plough was conducted in October and November, 2001. The ploughing was carried out on a carbonate humogley of powder clay texture. While working, the power unit work speed ranged from 4.9 km/h to 6.40 km/h, averaging 5.58 km/h. The ploughing was done at depth of 25.5 cm on the average. The ploughshares were used for 309 hours. The total of 226 ha were ploughed consuming 1.37 h/ha. Each ploughshare ploughed 22.6 ha. Total weight of all ploughsharesamounted to 38625 g prior the investigation and 30460 g at its end. It is by 8165 g i.e. 21.13% less compared to the initial weight. The loss of 760 and 930 g i.e. 33.5 and 38.1% referred mostly to D1 and L1 respectively. After the investigation they became useless for further work. Their use costs amount to HRK 10.06/ha.Tip of the ploughsahres D2 and L2 were useless after their work resulted in 33.3% loss of the initial weight. The third group of the ploughshares including ploughsahres D3, L3, D4 and L4 was characterized by an average weight loss of 770 g i.e. 18.5% whereas use costs ranged from 4.41 to 5.57 HRK/ha. They were able for continued ploughing. Tip of the ploughsahers D5 and L5, known for the loss of 27.1% of the initial weight became useless for the further work. Their costs were 3.03 HRK/ha.
