7 foot mower at 3.5 mph equals 2.673 acres per hour with overlapWell just wondering if there are any folks blessed with better then average math skills? How much more hay(in acres) would I have cut between a 7-8-or 9ft disc mower in a 10 hr day? All things being equal, same tractor, same ground speed/rpm, same field. Need someone to double check my math. So if in my little puddle jumper I cut at 3.5mph. That's 18480 ft in an hour, times a 7 ft mower is 129360 sq ft or ABOUT 3 acres per hour. For a 8 ft it's ABOUT 3.4, and 9 ft is ABOUT 3.8 acres an hour. So is my math on or did I miss a variable?
