sprayed my first field (pasture actually) with my t40 yesterday. all i can say is im super impressed with them. very easy to set up fields and operate. If you can run a JD monitor you could operate one of these drones. i will say, i dont think its the best idea to spray pastures with them, too much **** to fly around or at least the pasture i sprayed. finshed the 10 acres in 30 mins instead of hours with a four wheeler. granted the 4 wheeler probably would have been able to get more of it because of the trees. trade offs i guess!
