What actually sets this apart is the foldable frame that fits in a standard sedan trunk—we've had buyers pull up with a hatchback and drive away after a demo, no trailer needed, and that single-battery operation cuts weight penalty by about 30% compared to dual-battery rigs from last year.

You're looking at 14.67 hectares per hour with teh spray setup, which is better than most 30L tanks can sustain, thanks to those 12 high-pressrue nozzles delivering 8.1L/min at 8m width across the swath, and the 45L spreader covers 7m with air jet chute (check if your granular size matches the orifice plate—big urea prills can jam on the first load).

KB400 Agricultural Drone Foldable Design

The 40m obstacle detection range is pretty much required if you're flying full autonomous between power lines or treelines, and the dual 720p FPV cams let you see what the front and rear sensors are missing at dusk, though the controller screen is only 5.5 inches so you'll want reading glasses or a tablet mount for mapping overlays.

KB400 Drone Spraying Operation

Lead time is typically one week for standard orders, but we usually have stock on the 30L tank version; the 45L spreader adds 20 days or so because the auger motor comes from a different supplier, and the IP67 rating means you can hose it down after a calcium spray without worrying about corrosion on the controller board.

KB400 Drone Control System

80% of our agronomist clients go with the 2-battery plus 10-minute charger bundle rather than the single-battery base pack, since downtime between flights is basically zero that way—just swap and go, and the frame one year on the poly composites but not the prop tips if you clip a branch.

One thing nobody mentions: the folding hinges develop play after about 400 flight hours, so order a spare hinge kit when you buy—it's a $60 part that saves you shiping later, and it's not suited for vineyard row work under 3m spacing because the 8m spray swath overhangs by too much on tight turns.

Frequently Asked Questions

What are the MOQ and lead time for the KB400 drone?

Standard MOQ is 1 unit with a lead time of 1 week. Larger orders can be discussed, but that's the baseline.

Does the KB400 come with certifications or quality documentation?

Yes, it comes with CE and FCC certifications, plus a one-year warranty on the frame and software. We can provide test reports and compliance docs upon request.

Can the 30L spray tank and 45L spreader be swapped easily in the field?

Absolutely. The tank and spreader are modular and designed for quick swap without tools. Just clip them on depending on whether you're spraying or spreading.

How does the obstacle detection work, and does it cover all directions?

The front-facing obstacle detection covers up to 40m range. Combined with dual 720p FPV cameras front and rear, you get good situational awareness, but it's not full 360-degree coverage.

What's the best way to store the KB400 when not in use, given its IP67 rating?

The IP67 rating means it's dust-tight and can handle temporary submersion, but for long-term storage, keep it folded and in a dry, shaded place. The lithium battery should be stored at around 50% charge in a cool environment.
