As winter arrives and agricultural operations slow down, it is the perfect time to focus on maintaining your agricultural drone. Proper maintenance during downtime ensures that your equipment will be ready for maximum performance when spring comes. From cleaning and inspecting structural parts to checking the operating condition, winter maintenance is essential to extend the life of the drone and keep it in optimal condition. Here is a guide to the maintenance of the agricultural drone this winter.

1. Cleaning and maintenance

Clean the outside thoroughly
After a period of active season with spraying and scattering, chemical residues, dirt and debris can accumulate on the drone. Use a soft, damp cloth to wipe the outside, paying attention to the propeller, motors and nozzles. For stubborn dirt, use soapy water, but make sure that no moisture gets into the electrical components.

Inspect and clean the spraying system
If your drone is used to spray pesticides or fertilizers, clean the tanks, nozzles and hoses to remove any chemical residue. The remaining substances can corrode the components or clog the system, causing performance problems. Wash the system with clean water or a cleaning solution recommended by the manufacturer.

Remove debris from the propeller
The propellers are essential for stable drone flight. Check and remove any dust, mud or plant debris. Even minor obstructions can affect balance and efficiency. Replace damaged or worn propellers to maintain optimum performance.

2. Inspection of structural parts

Examine the frame for cracks or damage
The drone frame supports the entire structure and operation. Check it for cracks, bending or other signs of wear. Although aeronautical quality aluminum or carbon fiber frames are durable, it is necessary to periodically inspect them to prevent problems during flights.

Check the landing gear
Landing equipment often withstands considerable stress during operations. Make sure it is intact, resistant and without cracks or loose components. Replace worn parts to avoid landing accidents.

Inspect the fixes and connections
Collect any loose bolts, washers or connectors. Weakened components can lead to in-flight instability and cause accidents.

3. Operation status inspection

Check the health of the battery
Batteries are one of the most important components of a drone. Check them for swelling, leaking or corrosion. Store the batteries in a cool, dry place and keep them charged at about 50% if you do not use them for a long time. Charge and download them periodically to maintain their service life.

Test the engines
Run your engines to check for unusual sounds, vibrations or any inconsistencies in performance.

Calibrate sensors and flight control system
Winter is an excellent time to recalibrate sensors, including GPS, IMU and altimeter, to ensure precise operation. Firmware updates for the drone and flight control system should also be made to keep up with the latest improvements and bug fixes.

4. Storage and protection

Choose a safe storage environment
Store the drone in a dry, temperature-controlled place. Extreme cold can damage batteries and other sensitive components.

Protect electronic components
Make sure that the electronic parts of the drone are free of moisture before storing it.
