So you've got a big orchard or maybe a couple of hundred hectares of row crops, and dragging hoses or paying for ground rigs that tear up the soil — what you really need is something that can handle both liquid spraying and dry fertilizer spreading without having to swap machines, and the 50L model with its 80L spreader tank is actually pretty well suited for that dual role, though we usually tell buyers the 20L version is the sweet spot for most medium-sized farms because of that it's still easy to move around and the 2-2.5L/min flow rate covers about 8-10 hectares per hour without making you change batteries constantly.
It's not just about the tank size though — what really matters is that the whole frame is carbon fiber and aviation aluminun alloy, so the 42kg take-off weight on the big models isn't as punishing as it sounds, and the brushless motors are 2000 hours or so which is better than most of cheaper stuff we've seen, plus the IP56 rating means you can hose it down after a day in the field without worrying about the electronics shorting out.
Anyway, the flight time is only 10-15 minutes per battery — and that's with a full load, so you'll want at least two or three intelligent lithium packs (600-1000 cycles each) to keep running through a shift, but the quick-detach design makes swapping them out pretty fast, usually under a minute once you've done it a couple times.
One thing that catches people off guard is that the 40L and 50L models come with four centrifugal nozzles instead of teh two you get on the smaller ones, and the spray width jumps to 6-10 meters which is nice for open fields but not ideal for narrow rows or uneven terrain — we've had a few customers try them on hillsides and the wind resisance is only 10m/s, so basically anything above a light breeze will mess with your coverage pattern.
Lead time is usually 20 days or so for the JT 10L-404 QC and 20L models, but the bigger ones might stretch to 4-6 weeks depending on whether our company have the 70L or 80L spreader tanks in stock, and the 3-year the motors and frame but not the batteries or nozzles (check the fine print on that).
The entire drone, including the intelligent lithium battery and brushless motors, is covered under the 3-year warranty. The battery is rated for 600–1000 cycles, and the motors have a 2000+ hour service life, so you're covered for normal use. Just keep in mind the warranty doesn't cover damage from misuse or modifications.
Sure. The JT10L-404 QC covers 5–7 hectares per hour with its 3.5–5.5m spray width and 1–1.5L/min flow. The JT50L-404 jumps to 18–20 hectares per hour, thanks to its 6–10m spray width and 4 centrifugal nozzles that push up to 10L/min. So if you're doing large fields, the 50L is way more efficient.
We provide CE, FCC, and RoHS certifications for all models, plus a material compliance report for the carbon fiber and aviation aluminum alloy frame. If you need a specific certificate for your country, just let us know—we can usually arrange it within the lead time.
Our MOQ is 1 unit for sample orders, and 5 units for bulk. Lead time for the JT20L-404 is about 15–20 working days after payment, depending on stock. If you need a custom color or logo, add another 5–7 days.
Store it in a dry, ventilated area between -10°C and 40°C, with the battery at 50–60% charge. The drone has an IP56 waterproof rating, so it can handle rain and high humidity up to 90% during operation, but for long-term storage, keep it out of direct moisture to protect the electronics.
