"The Means of labor (also called instruments of labor) is a concept in Marxist political economy that refers to "all those things with the aid of which man acts upon the subject of his labor, and transforms it." (Institute of Economics of the Academy of Sciences of the U.S.S.R., 1957) Means of labor include tools and machinery (the "instruments of production"), as well as buildings and land used for production purposes and infrastructure like roads and communications networks and so forth. Labor, Itself defines "work, especially hard physical work."
The means of labor are one of three basic factors of the production process (Marx, 1967, p 174), along with human labor, and the subject of labor (the material worked on)." - (en.wikipedia.org 18.11.2021)
