Foldable 40L Pesticide Spraying Drone for Farms | Autonomous Flight & Obstacle Avoidance

We’d been looking for a solid mid-range unit for our regional spraying contracts, and this one from reliable overseas partner checked the boxes without a lot of back-and-forth on specs—the 40-liter tank and 40kg payload capasity are pretty much our sweet spot for the 15-20 hectare per hour coverage we need during peak season.

It’s built with aviation aluminum alloy, and the foldable arms are actually a nice touch for getting it in and out of the truck bed without scratching everything up, though the 10-15 minute flight time means you’re swapping batteries more often than you’d like—but the intelligent lithium pack with quick-detach does make that less painful.

You get a decent FPV camera at 720p for basic monitoring, and the front and rear radar for obstacle detection is better than most in this price range, but honestly most buyers go with the 10m/s wind resistance as a baseline for relaible field work, not the maximum spray width of 10 meters.

What it does is combine GPS, GLONASS, GALILEO, and BDS navigation, which gives you solid coverage even in slightly wooded areas, though we usually have stock on these but confirm lead time if you need them fast—the operating temperature range from -10°C to 70°C is fine for most climates (check your local conditions).

One concrete detail from handling these: the waterproof brushless motors hold up well in humid conditions, but the spray flow rate at ≤10L/min is pretty aggressive for spot treatments—better for broad-acre broadcast than precision work on small plots.

Anyway, when you order you’ll get teh drone with one battery, a charger, the spraying system with nozzles, and a one-year warranty, though packaging includes a quick-start guide that’s basically useless—we always rewrite our own SOPs for the field teams.
