Abstract

PURPOSE:To stably carry out lifting control regardless of rotation speed of a tilling device, by providing means for further dulling control sensitivity for automatic tilling control means at higher rotation speed of the tilling machine device. CONSTITUTION:As rotation speed of a tilling device 9 becomes higher, control sensitivity of automatic tilling control means are made duller and even when a tilling cover 10 is readily vibrated, the tilling device is not frequently subjected to lifting operation and the control is stably carried out. When the rotation speed is slow, the control sensitivity is enhanced and the tilling device is subjected to follow-up operation even in slightly rocking change of tilling cover and the control precision is enhanced and finishing precision of the tilling operation is enhanced.
