Maintenance Tips for Agricultural Drones

Spraying drones work in dust, moisture and chemicals. Neglect maintenance and you risk a motor, nozzle or battery failure in the middle of the busy season. Here are daily care routines and storage rules that apply to any model. For a detailed pre-season inspection, see our Agras T40 Pre-Season Maintenance Guide.

At the End of Every Working Day

Spraying system

• Fill the tank with clean water and run the pumps and nozzles to flush the system.
• Remove and clean the strainers; most blockages start there.
• Repeat the rinse after herbicide use.

Body, motors and propellers

• Wipe the body, arms and radar surfaces. Models with a high IP rating can be washed with low-pressure water; avoid spraying connectors directly.
• Check propellers for cracks or looseness and replace damaged ones with genuine parts.
• Turn the motors by hand; contact service if you feel friction or hear unusual noise.

Battery Care

• Let batteries cool after a hot flight before charging, or use the charger's cooling system.
• Avoid deep discharge; land before the battery drops below 20%.
• Keep connectors clean and dry; do not use a battery with signs of corrosion.
• For long-term storage, keep batteries at 40-60% charge in a cool, dry place. DJI smart batteries self-discharge to this level while idle. Storing them full or empty shortens cell life.
• Check the charge level every few months during long storage.

Electronics and Software

• Inspect cables and connectors for looseness or damage.
• Keep drone, controller and battery firmware up to date via the official app.
• Make a short test flight after updates.

End-of-Season Storage

• Clean and dry the spraying system thoroughly; leave no water in the tank.
• Remove batteries and store them separately at 40-60% charge.
• Store the drone in a cool, dry place out of direct sunlight, ideally in its case.
• Plan a service check before the next season.
