UT had a study years ago that did not support aerators. The only difference in an aerator and a sheeps foot roller is that the roller has a bulb on the end of the shank. Use plant roots.
Hard to dispute your post Ebenezer. Because I've read numerous studies that say the same thing. So let me be clear. I'm asking not disputing. Why is it when you dig a trench for a water line, electrical wire, etc that the grass will be much greener and more productive for years to come?
Bonus question: I have a neighbor with an aerator that's a big drum (holds 1000 gallons of water) with 'teeth' on it. Teeth penetrate the ground about 6". He bought it to aerate pastures. One year while planting cotton the tractor was struggling bad with the strip till planters. We hooked to the aerator and pulled it in front of the planters. It was night and day. Why did this help? How does pulling a 8000 pound drum over a field loosen rather than compact?
