Smart Farming Solution: HF T72 Spray Drone with Obstacle Avoidance and Terrain Following Radar

We've got the HF T72 in stock right now, about 20 units ready to ship form the warehouse — lead time is usually 5-7 business days on a standdard order. It's a big unit, 84kg without teh battery, so it ships on a pallet and you'll need a forklift or a couple of strong guys to move it around.

The 72L tank is the main selling point for most buyers because of that it cuts down on refill trips, especially on larger fields where every minute counts. It'll do 30 hectares an hour at a 16L/min spray rate, give or take depending on your nozzle setup and droplet size (you can dial it from 30 to 400μm). That spray width runs from 8 to 18 meters, so you can adjust for the crop rows.

Obstacle avoidance is front and rear radar with a 2-meter clearance, which works fine for most field edges and treelines — just don't rely on it for tight spaces around power lines. The terrain following handles up to a 45° gradient at 2m/s or less, but it's not a full autopilot for steep hillsides; you'll want to keep an eye on it.

Battery is a pair of 14S lithium-polymer packs at 42000mAh each, 60.9V — they're heavy, about 8kg per pack, and you'll want a spare set if you're running back-to-back jobs. Remote control range is 5km, but in practice with trees or buildings, we've seen it drop to 3km or so. FPV camera is 1920x1080 HD, clear enough for monitoring but not for detailed inspection.

Warranty is one year on the main frame and motors, but core components like the flight controller and radar are only covered for 3 months — that's a common limitation, so factor that into your maintenance budget. We usually include a COA with each unit, and you can request HPLC data on the spray pattern if you need it for compliance.
