In 1 st year the efficiency of a 3 share Moldboard plow, one disk and one roller without preventive maintenance function and in 2 nd year the same experiment but with preventive maintenance function were investigated. Based on the outcomes obtained by this research, using preventive maintenance engineering methods resulted in the reduction of lag period and expense by 48% and 84% respectively and efficiency rate the machine was increased 1.2 fold.
