| Abstract: | The leveling precising of the laser land leveling machine depends on the hydraulic controlling device. The optimized power matching and perfect work characteristics to the hydraulic system are importance on practice application. On the basis of hydraulic system studied on the laser land leveling machines at present in the world, and according to the style and the characteristics of middle power tractor hydraulic system often used in our country, a hydraulic controlling equipment with simple structure for the laser land leveling machine was developed. Through the experiment, it has been testified to be perfect with static and dynamic characteristics as wellashigh precision, low leak, low power consumption, no static sedimentation and optimized power matching. |
