DJI Agras T55: Verified Payload Specs and Deployment Checklist
Verified DJI Agras T55 spraying, spreading, lifting, battery and environment specifications, plus Reboot Hub's six-gate checklist for compliance, configuration, energy, maintenance and staged deployment.
Reboot Hub Industry Analysis
Verified Payload Specs and an Agricultural Deployment Checklist
Quick answer: DJI publishes the Agras T55 with a 50 L spray tank and 50 kg spraying payload, an 80 L spreader with a 55 kg operating payload, and an optional lifting system rated for a 40 kg operating payload. Those figures describe three different configurations. They do not establish field productivity, chemical approval, regulatory permission, battery-cycle economics, or support availability in a buyer's region.
Evidence boundary: Reboot Hub has not independently field-tested a production DJI Agras T55. Product figures below are attributed to DJI's current documentation; they are not Reboot Hub performance measurements. The deployment framework is Reboot Hub's technical and lifecycle analysis and must be validated against the exact aircraft, payload, material, terrain, climate, local law and support network. Reboot Hub is independent and is not affiliated with DJI.

DJI Agras T55 published specifications
What the headline numbers do not prove
No universal hectares-per-hour result
Tank volume and maximum flow do not determine total field throughput. Refill distance, turns, boundaries, terrain, application volume, battery swaps, material handling and weather can dominate the result.
No automatic regulatory approval
Aircraft capability is separate from aviation, chemical, environmental, land-access and operator requirements. In the United States, the FAA states that many dispensing operations fall under 14 CFR Part 137 and may also require an exemption and other approvals.
No universal material compatibility
DJI documents different augers and compatible granule sizes. A buyer still needs to test the actual fertilizer, seed, feed or treatment material for bridging, abrasion, discharge consistency and legal use.
No complete lifecycle-cost figure
The purchase package alone does not reveal battery replacement, charging fuel or electricity, cleaning labor, pump and nozzle wear, corrosion exposure, transport, training, insurance, downtime or local service availability.
Reboot Hub Agricultural Drone Deployment Gate
A T55 procurement decision should pass six gates before a buyer converts manufacturer capacity figures into a business case.
- Define one legal operation. Record the country, airspace, aircraft weight, substance, crop, operator qualification and operating method. Confirm aviation and chemical requirements with the applicable authorities before choosing hardware.
- Model the real application rate. Use the planned liquid volume or material mass per hectare, field geometry, refill location, route speed and safety reserve. Do not start from the maximum pump or spreader figure.
- Match the configuration. Confirm the tank, nozzle count, droplet target, spreader auger, battery, charger, generator, RTK and lifting components required for the job. Verify cross-generation interfaces before assuming existing equipment can be reused.
- Design the energy cycle. Calculate simultaneous battery demand, charge time, cooling, fuel or mains capacity, elevation and temperature effects. The aircraft should not wait for a single battery or charger during the intended work cycle.
- Build the contamination and maintenance plan. Define post-operation rinsing, chemical-safe handling, nozzle and pump inspection, sensor cleaning, corrosion checks, battery logs, firmware control and critical-spares availability.
- Prove the workflow in stages. Run dry setup checks, water-only tests where lawful, material calibration, obstacle review and a limited field trial before committing the full fleet or treatment area.
Compatibility and ownership risks
The T55 should be evaluated as a system, not an isolated airframe. DJI's FAQ says the T55 propellers match the T70P's 6223 model and the RC Plus 2 AG is compatible with the T100 and T70P. It also says the T55 spreader itself is not compatible with T100, T70P or T25P spreaders, although certain screw feeders are shared. Newer column-style battery interfaces may require adapter cables when used with older charging equipment.
These examples show why a fleet owner should maintain a serialised compatibility matrix for aircraft, batteries, chargers, controllers, spreaders, augers, nozzles, RTK equipment and firmware. A shared product-family name is not enough evidence of interchangeability.
Frequently asked questions
What is the DJI Agras T55 payload?
It depends on configuration. DJI lists a 50 kg spraying payload, a 55 kg spreading payload and a 40 kg lifting payload. They are not additive and should not be presented as one interchangeable payload rating.
Does the 400 kg/min spreader figure equal field productivity?
No. DJI identifies it as a maximum discharge rate for compound fertilizer. Field productivity also depends on the material, auger, target application rate, route, refill process, turns, weather and regulatory constraints.
Can a T55 be used for agricultural spraying in the United States?
Hardware availability alone is not authorization. The FAA says 14 CFR Part 137 governs covered agricultural dispensing operations, and operators may need a Part 137 certificate, an exemption, aircraft registration, a remote-pilot certificate and other applicable approvals. State and chemical-label requirements can also apply.
Can existing Agras batteries and chargers be reused?
Do not assume so. DJI documents two T55 battery options and warns that newer and older charging interfaces can require dedicated adapter cables. Confirm every battery, charger and cable combination before purchase or field use.
Is the T55 automatically a better investment than an existing Agras fleet?
Not necessarily. The decision depends on whether its supported configurations reduce total job time or risk after training, transport, charging, maintenance, regulation, parts and downtime are included.
Sources and methodology
Product data is taken from current DJI Agriculture pages, specifications, FAQ, launch material and manuals. Reboot Hub grouped those figures by configuration, identified the claims they cannot establish, and applied a six-gate procurement and deployment framework. FAA guidance is included only as a United States regulatory example; operators elsewhere must use their own national and local authorities. Manufacturer claims are not presented as independent field-test results.
