Hey man, Thanks on Dad's behalf. Yeah they are really cool machines no doubt! The technology has come a long, long way. I grew up on tractors but Dad worked a dairy farm and tobacco farm up in Tennessee for Grandad (R.I.P.). Dad is the one with stories! Plowing with the ole mule...wow! And now balancing out the treble and bass on the stereo inside the air conditioned cab! Haha...crazy! Dang nice machines for sure! People talked and John Deere listened! I think maybe one of my favorite options on Dad's M is the electrohydraulic 3pt hitch. Now that is sweet! Push 1 button at the end of the field to raise implement...make your turn...push 1 button to lower implement back to exact position. Love It! I know it's just a button but it's a dang cool button! Anyone else want to chime in about your favorite options on these new type machines...doesn't have to be an M model. Just curious...
