That's the same way I use mine on the M59 which is the machine we use 99% of the time. Toe to the top of the pedal and then toe to the bottom. No heel on the pedal.
I almost didn't get the M59 because I liked the JD two-pedal set up. And I still prefer the JD set-up..oh well...
Since most of the time is on the M59 I do make mistakes when I get on one of the other machines. But all that happens is that nothing happens. Toe is Toe. So it doesn't make a difference. It might if I was going in the other direction.

The M59 is pretty good on the pedal controls but the JD 4720 CUT was the bees knees for hydrostatic control and smoothness. I wish the M59 had cruise control like the Deere.
