Gentleman farmer
In the United Kingdom, the United States, and Canada, a gentleman farmer is a landowner who owns a farm (a gentleman's farm) as part of his estate and who farms as a hobby rather than for profit or sustenance. The Collins English Dictionary defines a gentleman farmer in the United Kingdom as one who is actively involved in farming but does not do it for a living, or a person who happens to own a farm but does not farm it himself (paraphrase).
