In short: Agricultural drone maintenance step by step: cleaning after spraying, storing DJI Agras batteries, and a checklist for before and after the season.

Agricultural drone maintenance determines whether your equipment gets through another season without breakdowns. Below is a checklist: cleaning after spraying, DJI Agras batteries, and preparation before and after the season.

After each working day

Personal protective equipment: coveralls, a filter mask, goggles and nitrile gloves – you are cleaning equipment with plant protection product residues. Clean in a ventilated area, away from wells and watercourses.
Flushing the system: fill the tank with clean water and flush the pumps, hoses and nozzles. After using sticky products and powders, remove the centrifugal discs and wash them with clean water, without abrasive tools [5].
Cleaning the body: use a damp cloth or low pressure. Do not use a pressure washer on the motors, connectors or electronics. The battery must not get wet [6].
Battery and drone connectors: clean off dust and residue with a cotton pad soaked in 95% alcohol or a microfibre cloth – ideally every day [3].
Propellers and arms: check for cracks, play and dirt.

Batteries – the rules

Charge only within the temperature range given in the manual, and don't leave batteries in a hot or freezing vehicle [2].
Don't store batteries at 100% – DJI batteries self-discharge after a set period [6].
Longer-term storage: 40–60%, in a dry, ventilated place out of direct sunlight [2][4].
At least once every 3 months, run a full charge and discharge cycle, then leave the battery at 40–60% [1].
At Agrodron we also check the voltage difference between cells – a large difference is a sign of battery wear.
Withdraw any battery that is swollen, leaking or damaged, and contact a service centre [6][7].
Store large stocks of batteries spaced apart and in a fireproof container [4][5].

After the season (October–November)

Empty the tank, flow meter, pumps and hoses completely – liquid left inside can freeze and damage the system [1][5].
Wash and dry thoroughly, and check for corrosion.
Batteries: 40–60%, removed from the drone, stored in a dry place [1][4].
Keep the drone in a cool, dry place; DJI gives a storage range of −20…40°C [1].
Record the number of cycles for each battery and the flight hours.
Post-season service at Agrodron – diagnostics, cleaning of motors and pumps, replacement of worn parts, software updates.

Before the season (February–March)

Update the firmware of the drone, batteries, remote controller and charger – all on matching versions [2].
Test each battery in the drone and test fast charging [3].
Check the connectors for corrosion (green deposits on the pins) [3].
Test the system for leaks and calibrate the flow meter.
Check the radars, cameras, propellers and RTK.
Pre-season service at Agrodron – drones ready for the first job of the season.

Service interval

DJI recommends a service every 100 flights or 20 hours of operation [1]. In peak season, even every few days.

Can I clean the drone with a pressure washer?
No. Do not direct high pressure at the motors, connectors or electronics, and the battery must not get wet.

How often should an agricultural drone be serviced?
DJI recommends a service every 100 flights or 20 hours of operation.
