"Obstacles" is I guess what I would call them. If I were mowing in a straight line that chart would work. But I'm having to make detours around bad spots so that adds to miles driven but not actual miles mowed because part of the time the mower is lifted up and not mowing, or going over areas already mowed.Well according to the chart if you are using a 6' mower at the speed you claim you are cutting close to an acre and a half per hour whether it's smooth or rough, so I don't understand why the chart is only good for someone cutting smooth ground, help me understand.
Yeah, I don't know that it takes in account for trees , brush piles, rocks, trash piles, etc, I think it's probably just giving an idea that with a certain width mower and you holding a set MPH mowing grass and weeds that you can expect to get X number of acres mowed per hour, I have checked this chart a couple of different times and have found it to be fairly accurate for what I was mowing."Obstacles" is I guess what I would call them.

Okay, you could mow in a circle if you wanted to nothing about the mowing chart says you have to mow in a straight line and there is some compensation in the chart for overlap and other things, it's just a general guide to give someone an idea of how much ground they are covering per hour.Statistical mowing charts are pointless. Nobody is mowing a flat straight line with no turns and a 100% steady speed. Every turn adds time. Every variation in speed adds/decreases time.
My point is the mowing chart is not practical in the real world. It's using static values that do not fit the reality of the majority of environments. Sure, it's a possibility but it's not a probability.Okay, you could mow in a circle if you wanted to nothing about the mowing chart says you have to mow in a straight line and there is some compensation in the chart for overlap and other things, it's just a general guide to give someone an idea of how much ground they are covering per hour.
That's funny, I just did 30 acres today and was within 20 minutes of what the chart said, so it was definitely practical in the real world for me, I do a good bit of mowing and tractor work for others so I use it occasionaliy when someone insist on an hourly rate, but in your situation it probably doesn't apply to you.My point is the mowing chart is not practical in the real world.
