There is no way to calculate real-time numbers because of not knowing how much difference the extra hp will make in the different grass sizes. The thickness of grass may slow the speed of the mower powered by the 28 Kohler much more than the mower powered by 8 more hp, and I feel assured this is where some of the difference came into play.
I will admit, I was pushing the new mower for all she had, and what I mean by that is, when taking 50 min. with the 66" deck, I would slow down a fraction in areas I did not with the new mower. I was trying to see just how fast I could cut a known acreage, I can promise the next time I cut the same area with the 72 it will not be as fast.
