In this research, 0 and 3% slopes were given to laserplane grade control system for two different soil conditions. Effect of different soil conditions on landlevelling was investigated. Unit operating cost and accuracy of machine were found. For this aim soil resistance, volume weight and specific gravity were found for two different soil conditions. Human factor wasn`t considered because operator wasn`t changed. Accuracy of landlevelling for sellected two grade angles was tested using with nodal network system. Excavation-filling amount was determined for two field and two grade during landlevelling. Operating costs for unit time and unit area were calculated at the end of operations. Based on the experiment results, it has been found that a variation for first field is more than second field to excavation-filling amount. Desired grades for two field were obtained. These trials were performed at Trakya University Tekirdag Agricultural Faculty Research and Application Fields that have 40x20 m dimensions. In these trials Fiat Mara model laserplane grade control machine that has got 3 m work with and New Holland M 95 traktor was used for pulling of laserplane grade control machine.
