From the sound,s of it you haven,t driven a 480 then.Because if you had you would know that your tx 68 would be left in the dust from the big pussy.I had a tx 68 so i know how they run and i have also driven a TF and both of them can,t compete with the 480,The machine is just awsome. Try cutting wheat at 48t_hr with your tx and see how you get on.Been there done that and got the T shirt and the hat.Only joking.There,s one thing i ran my tx for 6 season,s and all i put on it was 1 unloading belt and a water pump and 2 chopper bearing,s i think the TX has a much better build qaulity than the class and was very reliable.So we shall just have to wait and see how good the 480 is!
