DJI Agras T100 150 L Spreading System
W-9 and vendor pack with every quote
Shipped direct from the manufacturer
150 L tank, 400 kg/min max flow with compound fertilizer, and an effective spreading width of 3 to 10 m at DJI's tested condition of a 3 m working height and 1,100 rpm disc speed. Its own part number, ordered separately from the T100 aircraft.
01
This spreading system is ordered separately from the T100 aircraft, and DJI's own sources disagree on T70P fit
This 150 L spreading system is its own part number, sold on its own listing and not something the T100 aircraft ships with. DJI's own installation manual is explicit. This system fits the T100 only, and the aircraft's firmware must support it before use. DJI's own FAQ, a separate page, answers a related question differently. It states the spreader mechanism also fits the DJI Agras T70P, though the tank does not. The two DJI sources disagree, and we have not resolved it for you. We follow the manual, the more specific document, and sell this system for the T100. Flying a T70P? Call first and we will confirm your fit before you order.
02
DJI's own tested effective spreading width is 3 to 10 m, at a 3 m working height and 1,100 rpm disc speed
DJI measures the 3 to 10 m range under one stated condition. A working height of 3 m, a disc rotation speed of 1,100 rpm, and a uniformity requirement DJI calls CV under 30 percent. CV is coefficient of variation, DJI's own measure of how evenly material lands across the swath. At that condition, DJI's own measured broadcast width is 10 m. DJI states a faster disc speed widens the spread. So does a higher flight altitude. The figure moves with how you fly it, not only with what you load. Read this width as DJI's own tested ceiling, not a guarantee for your field, your material or your flight plan.
03
The 150 L tank feeds a centrifugal disc through a screw feeder, and DJI's own maximum flow rate is 400 kg per minute
The tank holds 150 L. DJI's own FAQ says the larger tank suits low density material such as grass seed. More work gets done per flight before you land to refill or swap batteries. The spreader structure is a centrifugal disc. The discharge structure is a screw feeder, DJI's own name for the auger that pushes material to the disc. DJI's own maximum flow rate is 400 kg per minute, measured with compound fertilizer specifically. DJI notes the true rate varies with the granule size, the density and the surface smoothness of whatever you actually load.
04
Four screw feeders cover materials from 0.5 to 10 mm, and only two of them ship standard
DJI ships two screw feeders standard. An extra-large feeder, already installed before delivery, rated 0.5 to 10 mm for fertilizer, wheat, feed and similar granules. A medium feeder, shipped loose, rated 4 to 6 mm for rice. Two more are optional purchases. A large feeder, 4 to 10 mm, for rice and fertilizer. A small feeder, 0.5 to 4 mm, for rapeseed and granular pesticides. DJI's own guidance is to choose the feeder by the material's apply rate, particle type and size. Remove the spinner disc and DJI names the system for plain discharge, suited to aquaculture and to fertilizing lotus fields.
05
DJI caps the load inside the spreading operation box at 100 kg, a limit the aircraft's own takeoff weight budget can lower further
DJI puts the load inside the spreading operation box at 100 kg, measured at sea level. DJI's own app recommends the actual loading weight for the aircraft's status and the surrounding conditions. Different material densities can lower the practical limit well below that ceiling. DJI's own installation manual adds that the true ceiling is bounded by the aircraft's own takeoff weight budget, not a fixed number. DJI's specification page uses the phrase Operating Payload for two other attachments on the same page. A spraying system at 100 kg, and a dual battery spraying system at 90 kg. Neither of those figures belongs to this spreading system. DJI's own name for this one is the load inside the spreading operation box.
06
DJI's own manual warns against caked fertilizer, straw and gravel, and names the screw feeder as the only part you should remove
DJI's own installation manual warns against large clumps of caked fertilizer, woven bags, straw and gravel. Foreign objects in the material can cause uneven discharge or blockage. The housing carries an IP67 ingress protection rating, tested under stable laboratory conditions to the IEC 60529 standard. DJI states plainly that the rating is not permanent. It can decline with age and wear, with a collision that deforms the seal, with a cracked shell seal, or with a waterproof cover left unsecured. The product warranty does not cover water damage. DJI names the screw feeder as the only part of the mounted system you should ever remove. Every other factory-mounted part carries its own do-not-disassemble warning.
07 FOR UNIVERSITIES, COLLEGES AND GOVERNMENT AGENCIES
DJI documents the feeders that ship, and we will confirm the exact build for your order before you buy
DJI's own manual documents what ships. An extra-large screw feeder already fitted, a medium screw feeder loose in the box, and a spare spinner disc. DJI's diagrams do not caption the spreader assembly itself with its own quantity marker. A complete, itemized packing list for the full unit is not confirmed, and we will not print one we have not verified. Tell us your aircraft and your material and we will confirm exactly what ships with your order before you buy.

Specifications
Tank and discharge
| Spreading tank volume | 150 L |
| Spreader structure type | Centrifugal disc |
| Discharge structure type | Screw feeder feeding |
| Max discharge rate | 400 kg/min, measured with compound fertilizerDJI's own condition: the maximum flow rate may vary with the granule size, density, and surface smoothness of other fertilizers |
| Max load inside the spreading operation box | 100 kg. DJI reserves the label "Operating Payload" for two different figures on its own specification page, 100 kg for the LS100 spraying system and 90 kg for the LS100-DB. The 100 kg figure here is this system's maximum load, not either of those.This is DJI's own label for this figure |
| Max load, sea level and density condition | Measured at sea level. The DJI Agriculture app recommends the actual loading weight for the aircraft's current status and surrounding conditions, and different granular densities change the practical limit below the 100 kg ceiling. DJI reserves the label "Operating Payload" for two different figures on its own specification page, 100 kg for the LS100 spraying system and 90 kg for the LS100-DB. The 100 kg figure here is this system's maximum load, not either of those. |
Effective spreading width
| Effective spreading width | 3 - 10 m, measured at a working height of 3 m with the disc rotating at 1100 rpm and a uniformity requirement of CV under 30 percent, at which the measured broadcast width is 10 m. DJI adds that a faster disc rotation and a higher flight altitude both widen the broadcast. |
| What moves the width within that range | Spreading range varies with the material's granule diameter, the screw feeder model fitted, the spinner disc's rotation speed, and flight altitude, per DJI's own installation manual, which recommends adjusting these variables to reach a 3 - 10 m spread |
Screw feeders and material compatibility
| Extra-large feeder | 0.5 to 10 mm granules: fertilizer, wheat, feed and similar materials. Ships standard, pre-installed in the spreader before deliveryStandard configuration confirmed independently on DJI's specification page, DJI's FAQ, and DJI's own installation manual's bill of materials |
| Medium feeder | 4 to 6 mm granules: rice. Ships standard, included loose in the boxStandard configuration confirmed independently on DJI's specification page, DJI's FAQ, and DJI's own installation manual's bill of materials |
| Large feeder | 4 to 10 mm granules: rice, fertilizer. Optional, purchased separately |
| Small feeder | 0.5 to 4 mm granules: rapeseed, granular herbicides, granular insecticides. Optional, purchased separatelyDocumented on both DJI's specification page and DJI's own installation manual |
| Choosing a feeder | DJI's own guidance is to choose the feeder by the material's apply rate, particle type and size |
| Discharge without the spinner disc | The spreading system can be used for plain discharge with the spinner disc removed, which DJI names as suitable for aquaculture and for fertilizing lotus fields |
| Materials to avoid | DJI's own installation manual warns against large clumps of caked fertilizer, woven bags, straw, gravel, or other foreign objects in the spreading material, which can cause uneven discharge or blockage |
Build and dimensions
| Dimensions | 900 mm x 820 mm x 920 mm |
| Ingress protection | IP67 under stable laboratory conditions (IEC 60529)DJI's own manual states this rating is not permanent and may decline with age and wear, that water damage is not covered by the product warranty, and that the rating can be reduced by a collision that deforms the seal, a cracked or damaged shell seal, or a waterproof cover that is not properly secured |
| Screw feeder replacement | The screw feeder can be swapped by the user for a different model to match the material being spread. DJI's own manual is the only part of the spreading system it names as user-serviceable; every other factory-mounted part is covered by its own do-not-disassemble warning |
Compatibility
| Aircraft fit | The DJI Agras T100. DJI's own installation manual states the 150 L spreading system is only compatible with the T100 and that the aircraft's firmware must support the spreading system, and instructs against using it with other productsDJI's own T100 FAQ states a different answer for one component: the spreader mechanism is compatible with the DJI Agras T70P, though the tank is not. DJI's installation manual and DJI's FAQ disagree on this point |
Compared with the DJI Agras T50 spreading system
| Flow rate | Increased 270 percent to 400 kg/minDJI's own comparison figure. Test results may vary based on different testing conditions, per DJI's own footnote |
| Spreading width | Increased to 10 m |
| Tank size | Enlarged to 150 L |
| Feeder and build | Diverse feeder configurations compatible with a wider range of materials, and the brim is embedded with stainless steel for greater durability |
