Agricultural drones perform spraying, spreading and field imaging. Useful productivity depends on payload, application rate, swath, refill and battery logistics, terrain following, obstacle sensing and positioning—not on tank size or maximum flight time alone.
Calculate hectares per hour from the target application rate and actual field geometry. Compare spray or spread system, positioning and correction service, communication range, batteries and charging set, folded dimensions, weather limits, local flight rules and spare-parts availability.
Use the table as a first comparison, not as a substitute for a technical agreement. Ask shortlisted manufacturers to confirm the current configuration, test method, duty cycle, charging or energy-supply boundary, applicable standards, warranty, local service and spare-parts plan in writing.
