The choice depends on the scale of operation and budget. Walk-behind models are more cost-effective, lightweight, and ideal for small, fragmented plots or terraced fields where maneuverability is key. Ride-on models are designed for large-scale commercial farming, offering significantly higher efficiency, reduced operator fatigue, and advanced features like GPS integration. For B2B buyers serving professional cooperatives, ride-on models provide a better long-term ROI despite the higher initial capital expenditure.
