Spray drones

The right spray drone is the one your field crew can keep moving.

Tank capacity is only the visible number. Real output comes from swath, application rate, refill cadence, batteries, label limits, crop canopy, and whether the drone is solving a wet-field or access problem.

Sortie productivity

The refill loop is the production line.

Spray output rises when every station is ready before the drone lands: mix, fill, battery, launch, pass, record, repeat. The weak station sets the day's ceiling.

The calculators below attach to the slowest stations in this loop. A large tank cannot fix a slow refill lane; a fast aircraft cannot outrun weak battery logistics.

  1. 01

    Mix

    Carrier volume, product label, agitation, and tender setup decide the batch rhythm.

  2. 02

    Fill

    Tank coverage shows how many acres fit before the next landing.

  3. 03

    Fly

    Swath, speed, overlap, and turns set the practical acres/hour ceiling.

  4. 04

    Refill

    Landing-zone layout and crew roles decide whether the aircraft waits.

  5. 05

    Swap battery

    Charging lanes and spare packs decide whether sorties stack or stall.

  6. 06

    Log

    Weather, field, product, rate, and as-applied records close the job.

Plan before you buy

The three operator calculators below sit at different points in the same field-day chain: time ceiling, refill cadence, and end-to-end productivity. Run them with conservative numbers before comparing aircraft or quoting custom work.

Start with the refill loop

The aircraft is visible, but the landing zone decides output. Before comparing models, estimate gallons per acre, acres per fill, battery cycle time, crew roles, and the support plan for parts during a narrow spray window.

Own vs hire

Own

Repeatable acres, trained crew, local support, stocked parts, and a clear compliance path.

Hire

Occasional rescue work, first-season testing, specialty crop access, or no appetite for batteries and spares.

Wait

No recurring job, unclear label fit, weak dealer support, or uncertain state pesticide rules.

Spray drone field guides

Read in this order: start with the mechanics guide to understand refill loops and crew workflows, then use the decision-path guide to identify your job (scout, map, spray, or service), then move to the model comparison to evaluate DJI, XAG, Hylio, and ABZ side by side.
