Abstract
PURPOSE:To carry out tilling work of flat finish without waving, by changing over a mode to slow actuation mode or quick actuation mode according to the tilt angle from the horizontal sensed by a longitudinal tilt sensing means. CONSTITUTION:The extent of unevenness of a field is sensed by a longitudinal tilt sensing means provided on a tractor (A). If the extent of unevenness is small (when the sensed values are within a given range), an elevating mechanism 19 is controlled by a slow mode. If the extent of unevenness is great (when the sensed values are outside the given range), the elevating mechanism 19 is controlled by a quick mode. The actuation of the elevating mechanism is capable of following the unevenness regardless of the size thereof.
