|---|---|---|
| Tank Capacity | Medium | Large |
| Flexibility | High | Medium |
| Transportation | Easier | Requires more planning |
| Refilling Frequency | More frequent | Less frequent |
| Large Farm Efficiency | Good | Higher potential |
| Initial Investment | Generally lower | Generally higher |
| Suitable Users | Small and medium operations | Large farms and professional services |
The correct option depends on your specific operating conditions.
5. Which Drone Is Better for Small Farms?
For small farms, a 20L agricultural drone may be more practical.
A smaller operation may not need the additional capacity of a 30L model.
The 20L option can provide:
- Flexible operation
- Easier transportation
- Lower initial investment
- Suitable spraying capacity
If the farm area is limited, a larger tank may not provide enough additional value to justify the higher investment.
6. Which Drone Is Better for Large Farms?
For large farms, a 30L agricultural drone may offer advantages.
The larger capacity can help reduce the number of refilling operations during long working days.
This may be particularly useful when:
- The farm area is large
- Water refill locations are far away
- Daily spraying volume is high
- Professional services are provided to multiple farms
A 30L model may help improve overall workflow efficiency.
7. Consider Battery Requirements
A larger payload generally requires a suitable power system.
When comparing a 20L and 30L agricultural drone, buyers should evaluate:
- Battery capacity
- Flight time under load
- Charging speed
- Number of batteries
- Battery replacement time
A 30L drone may require more energy to operate with a full load.
Therefore, the battery system should be evaluated together with the tank capacity.
A larger drone with insufficient battery support may not provide the expected productivity.
8. Consider Transportation and Field Conditions
The size and weight of the drone can affect transportation.
A 20L drone may be easier to transport using smaller vehicles.
A 30L drone may require more space and better transportation planning.
Buyers should consider:
- Distance between fields
- Road conditions
- Vehicle capacity
- Storage space
- Number of operators
For farms located in mountainous or difficult terrain, transportation flexibility can be especially important.
9. Consider the Type of Crops
Different crops may require different drone configurations.
A 20L drone may be suitable for:
- Small fields

- Large open fields
- Commercial farms
- High-volume spraying operations
However, the best choice also depends on spraying volume and operating methods.
10. Which Option Is Better for Agricultural Service Providers?
Agricultural service providers should consider their daily workload.
If the business provides spraying services to multiple farms every day, a 30L drone may help reduce refilling downtime.
If the service provider frequently works in different locations and difficult terrain, a 20L drone may provide greater flexibility.
Some professional businesses may choose to operate both configurations.
This allows them to select the appropriate drone for different customer requirements.
11. Which Option Is Better for Distributors?
Distributors should evaluate their target market.
A 20L agricultural drone may be suitable for customers who want:
