Abstract
Smallholder farmers produce a large share of food in many low- and middle-income countries, yet persistently low yields limit food security and rural incomes. Recent innovations in scale-appropriate farm machinery, including two-wheel tractors and dedicated small implements (seeders, transplanters, rotary weeders), digital decision tools, and innovative service models (custom hire, tool banks, rental/co-op arrangements) are changing how smallholders access power, do timely field operations, and adopt conservation agriculture. Evidence indicates mechanization can increase the timeliness of operations, reduce drudgery and labor bottlenecks, and contribute to higher productivity when paired with good agronomy and input access. However, constraints such as cost, access to finance and after-sales services, gendered labor impacts, land fragmentation, and sustainability risks remain. This review synthesizes recent evidence, highlights pathways by which machinery raises yields, discusses barriers, and proposes policy, design, and research priorities to maximise benefits for smallholders.
