so ive been running an Agras T40 for about two seasons now on a mix of corn and soy fields, mostly flat ground, nothing too crazy. the T40 has been solid honestly but the maintenance costs are starting to eat into margins pretty bad and a buddy of mine who does rice paddies over in the central valley keeps telling me to look at XAG or even some of the less-known brands coming out of Guangdong.

the main thing im worried about is the terrain following on uneven ground - we have some rolling sections that the T40 handles really well with the radar and lidar combo and i genuinely dont know if the cheaper options have figured that out yet. also the nozzle atomization matters a lot for the fungicide applications we do, getting droplet size wrong is basically throwing money in the dirt.

anyone actually made this switch or run them side by side? not looking for a sales pitch, just want to know if the field performance holds up.

ran an XAG P100 Pro for a full season last year alongside a neighbors T40 on adjacent fields. honestly the terrain following is pretty close - not identical but close enough that i stopped worrying about it after the first week. the lidar on the XAG is a bit more conservative, like it'll back off the speed on slopes that the Agras would just push through, which some guys see as a problem but i kind of appreciate it for the application consistency angle.

the nozzle situation is where you need to pay attention though. stock nozzles from XAG are fine for herbicide but if you're doing systemic fungicides you really want to swap in the hollow cone tips and dial the pressure settings manually, the auto modes tend to push droplet size bigger than i'd like for penetration into the canopy. it's fixable but it's extra work the Agras just doesnt require out of the box. maintenance costs are definitely lower, parts are cheaper and more available, but you're trading some of that savings for more hands-on tuning time.

not gonna lie i dont know the specific models you're talking about but just chiming in to say droplet size calibration stuff is way more important than people give it credit for. my uncle farms about 800 acres and switched spraying contractors last year and the new guy had slightly wrong settings for a late blight application and it was just... not great. so whatever platform you go with make sure whoever is operating actually understands the agronomy side and not just the drone side, those two things dont always come together in the same person lol
