This will bring back lots of tractor driving memories for your dad. Nicely done.
Alas we have one JD green among the four Case IH's here. I didn't learn to drive on my dad's JD's, but my DH taught me on a MM Jetstar. I've written several poems regarding my adventures on my steel horse. Working in the field is not all work. I feel closest to my dad when I'm discing in the field. Those are the kind of memories I hope you have given back to your dad.
