40L spray / 50kg spread tank · coaxial twin-rotor · 12ha/hour coverage · omnidirectional radar. Every unit ships with its real flight log, tested battery report and a written warranty — from $10,129 (Good grade) vs $22,000 new.
The T40 is the most proven mid-size agras platform ever built, and fleet-upgrade cycles are pushing well-maintained units onto the used market at 40% off new. For custom applicators, payback measured in weeks isn't marketing — it's arithmetic.
| Grade | Typical price | vs new ($22,000) | Warranty |
|---|---|---|---|
| Like New (<50 flights) | $15,849 | save $6,151 | 12 months |
| Excellent (<150 flights) | $12,999 | save $9,001 | 6 months |
| Good (150+ flights) | $10,129 | save $11,871 | 90 days |
Grades follow the published condition standard; every unit passes the same 27-point inspection.
The Agras series has model-specific wear points that generic "used drone checklists" miss. These are the three we weight hardest:
T40 intelligent flight batteries (30,000mAh class) with published cycle counts. Spray drones work daily in season, so battery pool size matters as much as the airframe — our listings state exactly how many packs and what wear. Full methodology on the battery health page.
A new DJI Agras T40 lists at $22,000. An Excellent-grade used unit at $12,999 saves you $9,001 — enough for two spare batteries and a year of accessories — while delivering identical flight performance. If the drone is for client work, step up to Certified Pre-Owned for the 12-month warranty and zero-downtime cover.

With documentation, yes — spray drones are tools, and working fleets maintain them like aircraft because they are. We verify pump hours, flow rates and radar calibration, and list what's been rebuilt.
The T50 carries more and flies newer avionics; the T40 costs ~$3,000 less and parts are everywhere. For most custom applicators the T40's economics win; large-acreage operations justify the T50.
Batteries (you want 3+), the spreader attachment if needed, and a generator/charging station for field work. We quote complete working kits, not bare airframes, for exactly this reason.
