Anyone heard anything about the 500 series tractors that will replace the 400? I was told they will be on the MF website around august and would have all the latest upgrades to date like A/C vent location. I was telling the man about the new Kubota M series with tilt hood ,pull out A/C condenser,corner exhaust but they are light weight tractors and thought MF was more tractor for the dollar. thats when he told me about the 500s .
