I dont think half of these guys know how big an acre is. There seems to be a lot of res. lawns in the 1.5 to 2 acres getting mowed here. And they can mow 4 acres an hour with a 60 Z.

out of every measurement that I know, I never forget what an acre is.

I've never measured a lawn when giving an estimate, and I am horrible at estimating sq footage by sight. I've never based an estimate solely on the size of the lawn, there's lots of other factors included in an estimate besides size. I've been trying to do square footage estimates lately and I just suck at it.

1 square mile 5,280 x 5,280 = 27,878,400 sq ft now divide that by 640 acres per sq mile and thats where the 43,560 sq ft comes from.

Now for easy calculating you can use the builders acre, which is 40,000 sq ft or an area 200 x 200 feet.

So yes I know what an acre is and yes 4 acres an hour is possible with a 60 Z
