This document discusses strategies to increase access to tractors for farmers in several African countries. It outlines a current business model where tractors are purchased and leased to farmers with financing from banks. Metrics are proposed to measure the program's outreach, impact on farmers' income, and overall impact. Challenges of impact evaluation are addressed, along with lessons learned from past experiences. Potential outcomes of the program are increased yields and income for farmers as well as improved access to agricultural machinery.
