Yesterday, I got my first taste of aeration and I must say...It kicked my azz. I've been in the lawn care business for over 20 yrs and never aerated a lawn. I guess it just happened that way I just bought a Turfco XT5 and used it to complete 3 - 12klawns that were side by side. The front yards had circle drives and were on 30 degree slopes. The back lawns were a little more level but had invisible pet fences and there was irrigation systems I had to manuever around throughout. It took me 3.25 hrs to complete and I made $350 using a gallon of gas I slept like a baby last night...after 2 beers, 4 Ibuprofen and a hot shower I'm thinking I may have to hire a kid.
