| Abstract | ||||
| The main aim of this research was to increase the operation efficiency of agricultural tractor to suit the conditions and potentials of the Egyptian farmer. This leads to increase the rates of the feddan production and raise the value of the yield per feddan. This meets the requirement to achieve the strategic goals of the agricultural development by modifying and developing the modern technology, especially the agricultural tractors to suit the local environment in all agricultural operations, including plowing. Laboratory experiments and statistical analysis for the data of the research were run and hydraulically steering was designed by suing a closed hydraulic circuit for the tractor. The main results obtained from the experiments are summarized in the following main points: 1-Mathematicl equations are derived to find the turning time every agricultural operation. 2-Maximum the saving percentage turning time, total time and costs of operation of about (55.2; 13.63; 18.37%) at the value of W/WB of about 0.39 respectively compared with the tractor before modification. 3-Decreasing the repeated technical problems in the steering equipments of the tractors. 4-Decreasing the operation, maintain and used spare parts in the steering equipments of tractors. 5-The modification suits all the agricultural operations even for small holdings in Egypt. | ||||
