The Laboy Tiller was developed to address the difficulty of land preparation of fields with laboy soil conditions. This study uses the set of scaling ingredients developed by PPPlab and CIMMYT to inquire about how the machine scaled from its initial project in San Luis, Aurora in the Philippines. In-depth interviews with farmers (n=28) and key informants (n=12) were conducted to answer the research questions. Results show that there was a lack of concerted efforts addressing some of the scaling ingredients, such as collaboration, evidence and learning, leadership and management, and public sector governance; hence, the Laboy Tiller did not scale much outside of San Luis town. However, it had a profound impact on the farmers of laboy areas in Aurora, and the concept of altruism emerged as an important ingredient that helped the Laboy Tiller to scale through the personal networks of the initial owners, and for them to value and maintain it through time. The consideration of the ingredient of altruism will then be helpful in the scaling efforts of other innovations by encouraging the beneficiaries to be participative in the continued uptake of the introduced innovation.
