Abstract
Tractor implements are mainly utilized for the tillage operation. The proposed hydraulic system control was implemented to experimental apparatus. An implement control system for tractor using proportional valve was fabricated to improve the working efficiency. Hydraulic circuit included the proportional solenoid valve and on/off solenoid valve and so on. This paper shows results of a specification and design of an implement control system for tractor using proportional valve for automation. It was conducted to evaluate response characteristics of the designed implement control system under experimental conditions of various input flow rates. The results of experiments showd that the response characteristics was sufficient to be used as the implement control system.
