Does anyone else get irritated when a manufacturer says a mower will mow 5 acres/Hr. or even 7? I realize that they are just taking top speed and multiplying it by deck width. Has anyone tried to mow this fast? I mowed 3 acres/Hr once and cut a baseball in half. Never saw it. Imagine the skidmarks there would be at the end of each row. I wonder sometimes if people are mowing the grass or just laying it down. God forbid somebody would quote a job at these rates. What your fastest? What is your norm?
