O.K. this is one of my customer yards .(sod) It's 90' x45" thats the complete yard in the picture. No back yard. All landscaped in stone. He wants it cut with 21" mowers.I bag it every week . Very picky old man too, 89 years old...Anyway i charge 45 for the job , it takes me 30 minutes. We use a 48'' mower every were else except him! so since he will not let me use a 48'' mower on his lawn , I want more money! With a 48'', It would take me 20 minutes or less, and you know, time is money.I want to raise him to 55. Do you think it would be to much???
