Incorporating modem and advanced technology(various electronic devices)to excavational machinery led to become more efficient,better quality and cost effective.The continuous development of equipment is also very important in the earth moving procedures which require significant time and expense to achieve the so-called"precision agriculture"or rather"precise management of agricultural inputs".One of the"precision agricultural"works is the land leveling.In recent years,land leveling is done with the use of a scraper(blade)mounted on the agricultural tractor.An electronic system controls the height of the blade automatically,without any operator intervention.In this paper,the field efficiency of the tractor MF6290,of 135 Hp horsepower,is calculated with a leveling blade of 4 m width,in the land leveling of rice cultivation,and in the rotation of different crops in different land preparation conditions(initial and final slope)in the area of Thessaloniki,northern Greece.The raw data revealed that the performance of the tractor ranged from 0.402 to 0.82 lha/h,on a slope 0%,while for surfaces with different initial and final slope,it ranged from 0.107 to 0.118 ha/h. 展开更多
