I mow about 6 acres in about an hour with lots of trees and shrub with my Ferris. It can mow at speeds up to 9.8 MPH when ground conditions allow
I'm still trying to figure out how you are mowing 6 acres in 1 hour.
Most of the mowing charts look about like this one from Exmark.
80% efficiency is about the best you can do with turns and overlap . 80% efficiance at full speed of 9.5 MPH with a 52" deck is still only 3.99 acres. And this does not account for you slowing down to mow around your trees and shrubs.

According to the chart, even with my 72" deck I would need to average over 10 MPH to cut 6 acres in a hour.
