DJI Agras T25P vs XAG V40: Compact Drones That Are Changing How the World Grows Wine

Somewhere between the ancient art of winemaking and the bleeding edge of autonomous flight, a quiet revolution is underway. Across vineyards in Bordeaux, Napa Valley, Hawke's Bay, Chianti, and the steep hillsides of Baden-Württemberg, compact agricultural drones are replacing tractors on slopes too dangerous to drive, spraying fungicide on vines too dense to reach, and generating crop health maps so detailed that winemakers can now harvest different sections of the same block at different times to optimize flavor profiles.

The precision viticulture market is projected to reach USD 9.51 billion by 2032, growing at a CAGR of 14.4%, according to DataM Intelligence. Europe leads with a 36% market share, driven by rising labor costs, climate variability, and the premium wine industry's relentless pursuit of quality. Meanwhile, the broader agricultural drone market continues its explosive trajectory — MarketsandMarkets projects growth from USD 2.63 billion in 2025 to USD 10.76 billion by 2030.

Why Vineyards Need Drones More Than Almost Any Other Crop

Vineyards present a unique set of challenges that make drone technology not just useful but often essential. Unlike flat broadacre crops where tractors operate efficiently, vineyards are frequently planted on steep hillsides where the best sun exposure and drainage produce the finest grapes — and where heavy ground equipment is either dangerous to operate or physically impossible to use.

In Germany's VDP estates, winemakers reported losing 60% of their grape harvest in 2021 because wet conditions prevented tractors from entering vineyards to spray fungicide in time. The vines needed protection from powdery mildew, but the soil was too saturated for ground equipment. Drones could have been above those vines within minutes, regardless of soil conditions.

Precision spraying in vineyards also delivers significant environmental benefits. Drones reduce chemical usage by 30–40% compared to traditional ground sprayers by targeting only the areas that need treatment. They eliminate soil compaction caused by tractor passes — protecting the soil biology that European winemakers increasingly view as critical to terroir expression. And they reduce worker exposure to pesticides, a meaningful safety improvement in an industry that still relies heavily on manual labor.

Beyond spraying, drones equipped with multispectral cameras generate NDVI (Normalized Difference Vegetation Index) maps that reveal vine vigor differences invisible to the naked eye. Winemakers at operations like Kendall-Jackson have used drone imagery since 2015 to identify stressed vines, optimize irrigation, and even select specific vineyard sections for premium wine production. In Italy's Bolgheri region, drone-generated vigor maps enabled selective harvesting — picking grapes from low-vigor zones (which concentrate more sugar) separately from high-vigor zones — to produce wines of measurably higher quality.

DJI Agras T25P: The Refined Solo Operator

The DJI Agras T25P, launched globally in July 2025, is the latest evolution of DJI's compact agricultural drone line. It retains the foldable, lightweight design that made the T25 popular with solo operators while adding meaningful upgrades through the new Safety System 3.0 and an improved spreading mechanism.

The T25P carries a 20-liter spray tank with a maximum payload of 20 kg for liquids and 25 kg for granular materials using the upgraded screw feeder spreading system 4.0. The Dual Atomizing Spraying System delivers a flow rate of 16 L/min with two sprinklers, expandable to 24 L/min with the optional four-sprinkler kit. Droplet size is adjustable from 50 to 500 micrometers — a wide range that allows operators to fine-tune application for everything from dense vine canopies to open field crops.

For vineyard work specifically, the T25P's Orchard Mode is a standout feature. This specialized flight mode uses the drone's high-resolution FPV gimbal camera combined with RTK positioning to automatically identify fruit trees and obstacles, then generate precise 3D flight routes that follow tree rows. On slopes up to 20 degrees, the drone performs automated surveying with obstacle bypassing and terrain following, creating the mapping foundation for subsequent spray operations — all at the push of a button.

Safety System 3.0 is a significant upgrade from the T25 predecessor. Millimeter-wave radar and a binocular vision system provide multidirectional obstacle sensing, with terrain following capability on slopes up to 50 degrees. For the steep hillside vineyards common in Mosel, Douro, and Côtes du Rhône, this slope tolerance is critical.

The DJI RC Plus controller features a 7-inch high-brightness screen with an 8-core processor, now 16% brighter than the previous generation and equipped with backlit buttons for low-light operations. The DB800 Intelligent Flight Battery charges in approximately 9 minutes using the C8000 charger, enabling continuous operations with a three-battery rotation. The T25P covers approximately 30 acres per hour during spray operations.

The entire system integrates with DJI SmartFarm, providing cloud-based flight logging, as-applied maps, and prescription map support for variable-rate application. For vineyard managers who want a complete, vertically integrated ecosystem from mapping to spraying to data analysis, the T25P within DJI's platform is difficult to beat.

"The T25P is like a Swiss army knife that happens to fly. Map, spray, spread — and it folds up small enough to fit in the back seat." — DJI Agriculture Operator

XAG V40: The Twin-Rotor Rebel

The XAG V40 takes a fundamentally different engineering approach. Where DJI builds on the traditional quadcopter architecture, XAG designed the V40 as the world's first tilting twin-rotor agricultural drone — essentially a bicopter that uses two electronically tilting rotor assemblies instead of four or more fixed rotors. This is not just an engineering curiosity. It has real-world consequences for vineyard operations.

The twin-rotor design generates a more concentrated, focused downdraft compared to multicopter drones. In vineyard spraying, downdraft pattern matters enormously — it determines how well spray droplets penetrate the vine canopy to reach leaves and grape clusters hidden within dense foliage. XAG claims that because each spray nozzle sits directly below its rotor, the resulting airflow pushes spray directly into the canopy rather than scattering it outward. For fungicide applications targeting powdery mildew and downy mildew — diseases that thrive on the undersides of leaves and within dense canopy interiors — this focused penetration can be the difference between effective treatment and wasted product.

The V40 carries a 16-liter liquid tank with a maximum flow rate of 10 L/min and adjustable droplet size from 60 to 400 micrometers. For spreading, a 25-liter granular container handles seeds and fertilizer at up to 40 kg per minute. The effective spray width reaches 10 meters, generated by the concentrated downdraft of the dual rotors.

Structurally, the V40 weighs 29.8 kg ready to fly (including battery and empty tank) and features a carbon-reinforced polymer body with IP67 waterproof rating — meaning it can be submerged in water for 30 minutes and survive. For vineyard operations where drones inevitably get soaked with fungicide residue, this full waterproofing is more than a spec sheet number. Operators can simply hose the entire aircraft down after each session, a practical advantage over drones with lower protection ratings.

The SuperX 4 Intelligent Control System is XAG's answer to DJI SmartFarm. It combines AI-driven flight algorithms, high-performance propulsion management, and interchangeable task systems — RevoSpray for liquids, RevoCast for granulars, and RealTerra for mapping. The RealTerra system is particularly relevant for vineyards: it uses an HD camera with AI image processing to perform autonomous aerial photography, field boundary recognition, fruit tree identification, map stitching, and 3D modeling. The resulting digital field maps can then drive variable-rate spray prescriptions, so the drone applies more fungicide to areas showing stress and less to healthy sections.

Navigation uses dual-engine RTK centimeter-level positioning with a multi-directional radar matrix including front dynamic radar and terrain radar. The obstacle sensing range reaches 1.5 to 40 meters with a wide field of view (horizontal ±40°, vertical ±45°). The V40 operates with XAG's RC Networking Mode under internet-denied conditions — useful for remote vineyards with poor cellular coverage.

Battery charging uses XAG's SuperCharge system with a water-cooling tank, reaching 30% to 95% charge in approximately 11 minutes. The 962 Wh lithium polymer battery provides approximately 16 minutes of hovering with no load and about 7 minutes with a full payload.

The V40's arms and propellers fold doubly, reducing handling volume by one-third — a meaningful advantage when transporting equipment up narrow vineyard access roads.

"Two rotors instead of four? That's not a drone, that's a drone on a diet. But somehow it sprays better than the big guys." — AgTech Blogger

The Vineyard Showdown: Where Each Drone Excels

For slope operations, both drones are capable but differ in tolerance. The T25P's terrain following works on slopes up to 50 degrees, while the V40's radar-based system handles complex terrain but without DJI's published slope rating. In the steep hillside vineyards of Germany, Portugal, and the Rhône Valley — where slopes routinely exceed 30 degrees — the T25P's validated 50-degree tolerance provides confidence.

Canopy penetration is where the V40 makes its strongest argument. The concentrated downdraft from the twin-rotor design delivers spray more directly into dense vine canopies. For vineyards battling powdery mildew in tight-canopy varieties like Pinot Noir, this focused airflow pattern can improve fungicide coverage on inner leaves and grape clusters.

Mapping and variable-rate intelligence are strong on both platforms. DJI's SmartFarm ecosystem is more mature and widely supported, with a larger network of dealers, training programs, and third-party integrations. XAG's RealTerra system with its AI-driven fruit tree identification and 3D modeling offers a compelling alternative, particularly for operators who want field mapping and spray execution on a single platform without cloud dependency.

Durability in vineyard conditions gives the V40 an edge. Its IP67 rating means complete waterproofing — the drone can be washed directly with water after fungicide operations. The T25P, while designed for harsh agricultural environments and tested extensively for durability, carries a lower ingress protection rating.

Ecosystem accessibility differs significantly. DJI's dealer network, training programs through DJI Academy (now available in 15 countries), and integration with established precision agriculture tools make the T25P easier to adopt for operators already within the DJI ecosystem. XAG offers strong support through its dealer network and has a particularly well-established presence in Asia-Pacific and Oceania markets — including New Zealand, where XAG drones are already working vineyards in Hawke's Bay.

The T25P's optional four-sprinkler configuration with Reverse Directional Spray during manual flight simplifies operations in narrow vineyard rows, eliminating the need for turnaround maneuvers at row ends. This is a small but meaningful convenience feature for vineyard operators who spend their days flying the same row patterns.

Beyond the Vineyard: Where Drone Software Makes the Wine Better

Here is the insight that drone manufacturers do not sell but that vineyard managers increasingly discover: the most valuable output of a vineyard drone is not the spray it delivers but the data it collects. NDVI maps, thermal imagery, canopy volume measurements, and vigor zone classifications — these datasets, when properly processed and integrated with vineyard management systems, transform winemaking decisions.

In Italy's Chianti Classico region, drone teams have used NDVI and thermal data to design precision irrigation systems, recovering from yield losses by mapping vine water stress at row-level resolution. In Bolgheri, vigor maps enabled two-class selective harvesting that produced demonstrably better wines. In California, Kendall-Jackson uses drone imagery to decide which vineyard sections to source for specific wine blends.

But none of this happens automatically. Raw drone imagery needs processing through photogrammetry software, NDVI calculation, georeferencing, and integration with block management databases. Flight plans need optimization for vineyard-specific geometries — row spacing, trellis height, headland width. Real-time data from drone sensors needs visualization dashboards that vineyard managers can actually use on a tablet while walking between rows.

This is exactly what A-Bots.com builds. Custom precision viticulture software that connects drone data to vineyard decisions — from NDVI visualization overlays to automated spray prescription generation, from flight planning optimized for row-based vineyard patterns to mobile dashboards that put actionable insights in the winemaker's hands. Our QA and testing services ensure that these systems perform reliably when it matters most — during the narrow treatment windows when vines need protection and every hour counts.

Choosing Your Vineyard Drone

Choose the DJI Agras T25P if you value a mature ecosystem with extensive dealer support and training, you need validated terrain following on steep slopes, and you want seamless integration with DJI SmartFarm's cloud-based analytics. It is the safer, more established choice — particularly in Europe and the Americas.

Choose the XAG V40 if canopy penetration is your top priority, you operate in wet conditions where IP67 waterproofing matters, and you prefer a modular, AI-driven platform with strong mapping capabilities. Its twin-rotor design is genuinely differentiated, and its presence in Oceania's vineyard market provides real-world validation.

Either way, the drone is only half the story.
