Large open field? 8 acres of turf grass is different in my mind than field grass. I have a customer with 9 acres that I maintain, 4 acres is turf and the rest is pastures. What is the frequency of cutting the area? Wouldnt think it would be weekly service on a 8 acre "field". If they are thinking about you cutting it once month it's not worth the wear and tear on you 54" ztr and will take you twice as long as it should.
