To provide a control method of a work machine, a control program for a work machine, a control system for a work machine, and a work machine that can easily reduce burden on an operator associated with operation.SOLUTION: A control method of a work machine 3 includes: activating a first restriction portion 48 based on detection results of an object to be detected in a monitoring area surrounding the work machine 3; and switching between validity and invalidity states of the first restriction portion 48. The first restriction portion 48 restricts an operation of a first drive portion (a hydraulic motor 432) that drives the work machine 3. Here, the first restriction portion 48 is switched between the validity and invalidity states depending on an operation state of an operation device 35 related to an operation of the first drive portion, and the first limiting portion 48 is switched to the validity state at least before the operation device 35 is operated.SELECTED DRAWING: Figure 2 【課題】操作に係るオペレータの負担を軽減しやすい、作業機械の制御方法、作業機械用制御プログラム、作業機械用制御システム及び作業機械を提供する。【解決手段】作業機械３の制御方法は、作業機械３の周囲の監視エリアにおける検知対象物の検知結果に基づいて、第１制限部４８を作動させることと、第１制限部４８の有効と無効とを切り替えることと、を有する。第１制限部４８は、作業機械３を駆動する第１駆動部（油圧モータ４３２）の動作を制限する。ここで、第１制限部４８の有効と無効とは、第１駆動部の動作に係る操作装置３５の操作状態に応じて切り替えており、少なくとも操作装置３５が操作される前においては第１制限部４８を有効にする。【選択図】図２
