Using Automatic Milking Systems (AMS) as an example we use the work of Bourdieu to illustrate how technology can be seen as restructuring dairy farming practices, what it is to be a dairy farmer, and the wider field of dairy farming. Approaching technology in this way and drawing upon the ‘thinking tools’ of Pierre Bourdieu, namely field, capital and habitus, the article critically examines the relevance of Bourdieu's thought to the study of technology. We expand on Bourdieu's types of capital to define what we have called ‘hybrid’ capital involving human‐cow‐technology collectives. The concept expresses how new technology can shift power relations within the dairy field, affecting human‐animal relations and changing the stock person' habitus. Hybrid capital is produced through a co‐investment of stock‐keepers, cows and technologies, and can become economically and culturally valuable within a rapidly restructuring dairying field when invested in making dairy farming more efficient changing farmers' social status and work‐life balance. The article shows how AMS and this emergent hybrid capital is associated with new but contested definitions of what counts as ‘good’ dairy farming practice, and with the emergence of new modes of dairy farmer habitus, within a wider dairy farming field.
