DJI Agras T20 vs T30 vs T40: Crop spraying drone price comparison

Overview of the DJI Agras spraying drone series

Introduction to DJI Agras technology and applications

The DJI Agras series is a line of unmanned aerial vehicles designed for automated pesticide spraying. These drones feature AI systems, multi-directional radar, and RTK positioning, enabling precision spraying while saving up to 30% pesticide and 40% water compared to manual methods.

Among current models, the DJI Agras T20, T30, and T40 represent three productivity tiers. The T20 is considered the most balanced between cost and performance—ideal for medium-scale farms and cooperatives.

Key differences between T20, T30, and T40 in agricultural use

These three DJI Agras drones are sequentially upgraded in tank capacity, payload, and technology:

• T20: 20-liter tank, sprays up to 12 ha/hour — suitable for small fields.
• T30: 30-liter capacity, 30% higher performance, equipped with front-rear radar.
• T40: flagship model with dual-centrifugal spraying and AI crop recognition camera, up to 16 ha/hour.

Due to these differences, the T20 price is 20–40% lower than the T30 and T40, making it a popular choice among small and mid-sized farmers.

Why DJI spraying drone prices vary by model

Price variations come from four main factors:

1. Tank size and spraying power – larger tanks require stronger motors and components.
2. Sensors and processors – higher models like the T40 use 360° radar and AI target recognition.
3. Frame and battery design – carbon fiber and high-capacity batteries increase production cost.
4. Smart features – such as automated mapping, obstacle avoidance, and mission management.

Thanks to a good balance of technology and affordability, the DJI Agras T20 price remains the most competitive in the mid-range segment.

Technical specifications and performance comparison

Spray capacity and real-world efficiency

Model	Tank capacity	Max spray rate	Spraying efficiency (ha/hour)
T20	20 L	6.0 L/min	10–12
T30	30 L	8.0 L/min	12–14
T40	40 L	10.0 L/min	14–16

From the table above, the T20 delivers stable performance of 10–12 ha/hour, sufficient for farms of 10–30 ha. The T30 and T40 serve larger-scale operations but require significantly higher investment and maintenance costs.

Operational stability and handling

• T20: foldable frame, easy transport, short charging time, stable in winds ≤5 m/s.
• T30: dual-pump system with stronger output, suitable for complex terrain.
• T40: full-surround sensors for stable operation even on uneven fields.

Cooperatives often note that the T20 is more energy-efficient and easier to maintain—an advantage for reducing total operating costs.

Impact of radar and GPS RTK technology on spraying performance

Radar and GPS RTK allow positioning accuracy within ±1 cm, preventing over-spray or missed areas.

The T40 and T30 include omnidirectional radar, while the T20 uses basic front-rear sensors yet still maintains consistent performance on flat terrain.

Thanks to these features, the T20’s spraying accuracy reaches 90–95% of higher models, while costing only 60–70% as much.

Updated DJI Agras price comparison

Model	Reference price (VND)	Ideal user
DJI Agras T20	190–240 million	Small farms, cooperatives
DJI Agras T30	270–320 million	Mid-sized farms
DJI Agras T40	380–450 million	Agribusiness enterprises

Thus, the T20 remains the most economical option especially for those seeking high efficiency at a lower initial cost.

Price difference analysis

• The T20 is roughly 30% cheaper than the T30 due to smaller capacity and fewer sensors.
• The T40 costs about 25% more than the T30 due to AI and crop-mapping camera systems.

For small-scale production, the T20 offers the best cost-to-performance ratio.

Additional factors affecting agricultural drone prices:

1. Replacement part and battery costs
2. Import rates and tax policies
3. Official DJI distribution availability
4. Warranty and after-sales support

Overall, the T20 maintains a stable price due to common spare parts and lower maintenance costs.

Investment efficiency of the DJI Agras T20

Annual operation and maintenance cost

Operating expenses—including batteries, spraying liquids, labor, and maintenance—average 20–25 million VND/year for the T20, compared to 30 million for the T30 and 40 million for the T40.

Payback period comparison

• T20: 1.5–2 years
• T30: around 2.5 years
• T40: 3 years or more

Thanks to its reasonable price, the T20 allows small investors to recover capital quickly through rental spraying services and stable productivity.

Economic benefits of the T20 for farmers

• Reduces labor costs by 60–70%
• Saves 25% on pesticide use
• Increases spraying efficiency 5–10× over manual methods
• Easy to operate and suitable for most crop types

With an investment under 250 million VND, the T20 is the most efficient option for small to medium farms.

Choosing the right drone for your farm size

Recommended models by farm scale

• Farms under 30 ha: T20 for best cost efficiency
• 30–60 ha cooperatives: T30 for higher productivity
• Large farms over 80 ha: T40 for superior performance

Due to its affordability, the T20 remains the top-selling drone in Vietnam’s agricultural market.

Model recommendations by crop type

• Rice, corn, vegetables: T20
• Industrial crops (coffee, pepper): T30
• Fruit trees and tall crops: T40 with wide spray range and AI vision

Choosing the right model requires balancing performance, terrain, and the current T20 drone price to maximize return on investment.

Where to buy genuine DJI spraying drones in Vietnam

Buy only from authorized DJI distributors offering 12–24-month warranties and UAV training. Some dealers also provide maintenance and RTK software updates to ensure stable long-term operation.
