I'm sure we've all seen the charts on manufaturer's websites and the formula for calculating acres per hour for a certain size deck at a certain speed... I feel for the most part that these charts and tables are unrealistic. I thought it would be helpful for everyone to share some real world numbers. Please include machine, type of area you're cutting (football field, or a condo), and any other info that may be helpful. I see about 1.5-2 acres per hour out of my 60" Z830A Deere on the 1/2-1 acre residential and commercial acounts I do. One lot I mow every other week is about .8 acre, and takes about 35 minutes. I think if I got it out in the open on weekely cut grass I could see close to 4 out of it.
