Short answer: For large farms the Agras T50 is the stronger choice, with a wider spray swath, higher flow rate and faster flight than the T40; the T40 suits smaller farms on a tighter budget. Neither model is in HobiTech's current range: for new purchases we supply DJI's current Agras T70P and Agras T100, priced on request for your configuration.
Key takeaways
- Both carry a 40 L spray tank and can also spread granular material.
- The T50 sprays a wider swath at a higher flow rate than the T40, so it covers more ground per flight.
- The T50 adds a binocular vision system to its active phased-array radar for terrain and obstacle detection.
- T50 for large-scale farms; T40 for smaller farms that want a lower-cost machine.
- HobiTech's current Agras models are the T70P (70 L tank) and T100 (100 L tank), both priced on request.
