PROBLEM TO BE SOLVED: To automatically stop an operation when a load applied to a working vehicle comes to an excessive load by an operation, and determine whether continuation of a working operation allowed thereafter is stopped or not, in the working vehicle for carying out working by various kinds of operation levers. SOLUTION: In this automatic stopping method for an working operation, a load value applied to a working vehicle by a boom turn-up operation of the first working operation is detected, the boom turn-up operation is automatically stopped when a detected value therein is a specified value or more, and the permission of the second working operation is determined after the stoppage, based on the boom turn-up operation. A boom turn-down operation is stopped as a prohibited-side operation (S36) when a value R indicating a condition of a load changing during an operation of the boom turn-down operation (yes in S32) that is the permitted second working operation exceeds a specified value Rs+dR continuously during a prescribed time T1 (yes in S33, S34).
