Comparing the Agras T55 with the Agras T70P: What Farmers Should Know

Key Takeaways

• The T55 carries a 50L spray tank while the T70P carries 70L, meaning fewer refills per mission on the larger model
• Counterintuitively, the T55’s standard flow rate (up to 40 L/min) is higher than the T70P’s (up to 30 L/min)
• The T70P’s DS system supports a 100L spreading tank against the T55’s 80L, with a higher maximum lifting payload
• Both aircraft share the same RTK hovering accuracy, operating temperature range, and wind resistance rating
• Afri Air supplies and configures both models, helping farmers match the aircraft to their actual operation

Two Capable Aircraft, Different Jobs

Farmers weighing up the DJI Agras T55 against the DJI Agras T70P are often comparing two aircraft that look similar on paper but are built for different operational scales. Both spray, spread, and lift. Both use RTK positioning for accurate flight. Where they differ is in tank size, flow rate, and payload capacity, and those differences matter more than they might first appear.

This comparison sets out what each model actually offers, based on their official specifications, so the decision comes down to what your fields and mission length actually require.

Spray Tank and Payload Capacity

The most visible difference is tank size. The T55 carries a 50L HDPE tank with a 50kg operating payload, while the T70P steps up to a 70L tank with a 70kg operating payload. On paper, this looks like a straightforward case of “bigger is better” for larger fields, since a bigger tank means fewer landings to refill during a single mission.

That said, a larger tank also means a heavier aircraft. The T55 weighs 45kg with its standard DB1050 battery, while the T70P weighs 52kg with its DB1580 battery. Farms with tighter access points, more manual handling during turnaround, or smaller support teams may find the lighter T55 easier to work with day to day.

Flow Rate: Where It Gets Interesting

This is where the comparison surprises most farmers. The T55’s standard two-nozzle configuration delivers a maximum flow rate of 40 L/min, rising to 50 L/min with the optional four-nozzle mist setup. The T70P’s standard configuration delivers a maximum flow rate of 30 L/min, rising to 40 L/min with its optional four-nozzle setup.

In other words, the T55 actually sprays faster per minute than the T70P. What the T70P offers instead is a larger tank to sustain a mission for longer before needing to land and refill. Both aircraft share the same droplet size range (50 to 500 micrometres) and the same effective spray width (4 to 11 metres), so precision and coverage width are comparable. The real trade-off is between a faster application rate on a smaller tank versus a longer run time on a larger one.

Spreading and Lifting Capability

Both models support optional spreading and lifting systems, but capacity scales with the aircraft. The T55’s DS80L spreading system holds 80 litres with a 55kg operating payload, delivering up to 400kg/min for compound fertiliser and an effective spreading width of 3 to 10 metres. The T70P’s Spreading System 4.0 increases this to a 100 litre tank with a 70kg maximum load, at the same 400kg/min discharge rate and spreading width.

For lifting, the difference is more pronounced. The T55’s DL100 system supports up to 40kg, while the T70P supports up to 65kg. Farms using their aircraft for occasional equipment or supply transport around the property may find this gap relevant, particularly for heavier loads.

Positioning, Safety, and Operating Conditions

Here the two aircraft are essentially matched. Both hold RTK-enabled hovering accuracy of within 10cm horizontally and vertically, both are rated for operation between 0°C and 40°C, and both maintain stable flight in wind speeds up to six metres per second. Maximum configurable flight radius is 2km on both models.

Both aircraft also use millimetre-wave radar with a sensing range of up to 60 metres for obstacle awareness. The T70P’s safety system is explicitly branded Safety System 3.0 with a Tri-Vision setup, while the T55 uses a comparable radar and vision configuration. In practical terms, farmers should not expect a meaningful difference in flight safety or precision between the two.

Choosing Between the T55 and T70P

For farms running shorter missions across moderately sized fields, or where a lighter, more manoeuvrable aircraft suits the operation, the T55’s higher flow rate and lower weight are worth considering. For farms covering larger areas where minimising the number of tank refills per mission matters more than per-minute application speed, the T70P’s larger tank and higher lifting capacity offer a practical advantage.

Neither aircraft is simply an upgrade of the other. They are built for different balances of speed, capacity, and mission length, and the right choice depends on how your fields, crops, and working patterns actually shape a typical day of operation.

Frequently Asked Questions

Does the T70P spray faster than the T55?

No. The T55’s maximum flow rate (up to 40 L/min standard, 50 L/min optional) is actually higher than the T70P’s (up to 30 L/min standard, 40 L/min optional). The T70P’s advantage is tank size, not application speed.

Which aircraft is lighter to handle on the field?

The T55 is lighter, weighing 45kg with its standard battery compared to the T70P’s 52kg. This can matter for farms with more manual handling during battery changes and refills.

Is positioning accuracy different between the two models?

No. Both aircraft achieve the same RTK-enabled hovering accuracy of within 10cm horizontally and vertically.

Can both aircraft handle spreading and lifting tasks?

Yes. Both support optional spreading and lifting systems, though the T70P offers a larger spreading tank (100L versus 80L) and a higher lifting payload (65kg versus 40kg).

What operating conditions are both aircraft rated for?

Both the T55 and T70P are rated for operation between 0°C and 40°C and can maintain stable flight in wind speeds up to six metres per second.

Choosing between the Agras T55 and Agras T70P comes down to matching the aircraft to your actual fields, mission lengths, and typical workload rather than picking the larger model by default. As an authorised DJI distributor, Afri Air supplies both aircraft along with their spraying, spreading, and lifting attachments, and can talk through which configuration suits your farm.
