All deere tractors with 8R 230,250,280,310,340,370,410 has a vistronic fan clutch drive which would have started around 2020 or 2021 anything with the number like 8400R and before back to the 8030 series has varicool fan drive which is not the best idea in the world the the 8020 back to years ago used viscous fan drives other than the 8520 it used for he vistronic fan drive.
