What these figures mean in practice

Our reading of the specifications above. These are not manufacturer claims — every number below is derived from the table, and the trade-offs are ours.

The fastest-emptying tank in the range

At the optional four-nozzle rate of 50 L/min the 50 L tank is gone in sixty seconds flat, and even the standard two-nozzle 40 L/min empties it in a minute fifteen. Nothing else in the Agras line moves liquid that fast relative to its capacity — the T100 carries twice as much but takes two and a half minutes to put it out. This is a machine built for high application rates over short passes, and it will expose a slow ground crew faster than any other model here.

The only one specified to work below freezing on the ground

The airframe is rated 0–40 °C like its siblings, but the D8000iE generator and C7000 charger are both specified from -20 °C, where the T70P and T100 equivalents start at 0 °C. For anyone doing early-season work in cold country, the ground equipment is the part that usually fails first, and here it is rated for it.

Lighter ground kit than the bigger models

The D8000iE is 46 kg against the D14000iE's 87 kg, and the C7000 is 8.5 kg against the C12000's 13.13 kg. The trade is charge power — 7000 W three-phase against 12000 W — but with the smaller DB1050 pack at 20 Ah the charge time still comes out at eight to nine minutes. Half the weight to move between paddocks for the same turnaround is a real operational difference.

Two batteries, two aircraft

The DB1050 is 8.3 kg and 20 Ah; the DB1580 is 11.7 kg and 30 Ah. Fitting the larger one adds 3.4 kg to the airframe but raises spraying maximum takeoff weight by 4 kg and spreading by 4 kg — so the heavier pack very nearly pays for itself in payload while adding half again as much energy.
