so ive been running an Agras T40 for about 8 months now doing contract spraying for a few farms in my area, mostly corn and soybeans, and honestly the machine is great but the cost per acre when you factor in maintenance and those ridiculous DJI enterprise support fees is starting to eat into margins pretty bad.

been looking at some of the XAG stuff and honestly even some of the cheaper units like the TTA M8A which ive seen come up a few times on here. the specs on paper look fine ? similar tank capacity, supposedly decent radar terrain following ? but i have no idea how the actual field performance compares, especially the nozzle atomization quality because that actually matters a lot for fungicide applications where droplet size is everything.

anyone made a switch like this or running both? curious if the autonomy on those units is as reliable as advertised or if youre babysitting it more than the Agras

ran an XAG P100 for almost a full season last year alongside my T20 and honestly the XAG held up better than i expected. terrain following was a bit twitchy in hilly fields, kept wanting to climb more than necessary which wasnt ideal for application height consistency, but on flat ground it was solid. the nozzle system is different though ? you really need to dial in your flow rate settings manually at first because the defaults are not calibrated for most US label requirements. took me probably 3 field days to get comfortable with it.

the support thing is real, XAG has dealers but its spotty depending on where you are. if youre not near a metro area good luck getting anyone on the phone fast when something breaks mid season.

not sure about the TTA specifically but i looked into them a while back and the main thing that scared me off was parts availability. like the Agras ecosystem has problems but at least i can get a motor or a pump diaphragm in a reasonable timeframe. heard some horror stories about waiting 6 weeks for a replacement part on some of the lesser known brands and thats just not viable if youre doing contract work with clients depending on you for timing-sensitive sprays
