Abstract

PURPOSE:To enable sure escape from an over-loaded state of a drafting power, by providing a draft-controlling apparatus with a specific over-load avoiding mechanism. CONSTITUTION:In the drawing of a plough, etc., a top link bracket 10 is tilted by the drafting force applied by a working part and the tilt is detected by a draft detection sensor 13. When the detected value A of the draft is higher than the preset draft level B, it is judged as an over-loaded state by a controller and the working part is lifted by a prescribed amount with an over-load avoiding mechanism neglecting the fluctuation of the drafting force. The over- loaded state can be surely avoided by this process.
