TRACTOR WORKING MACHINE CONTROLLER

PURPOSE:To provide the title controller designed to horizontally control a tractor working machine while preventing unnecessary operation by making a control in such a manner that when an angle-of-rotation sensor to detect the revolving angle of a tractor detects a value not less than a specified level, a control is made so as not to make a control by a tilt-detecting sensor. CONSTITUTION:A control part 4 makes a horizontal control for the left-and-right direction of a tractor working machine 2 through the voltage from a tilt- detecting sensor 13 to detect the left-and-right tilting of the working machine 2. During the revolving of the tractor, the angle of rotation of the handle is detected; if this value is not less than a specified level stored in the control part 4, a control is made so as not to make a horizontal control.
