Once attached to the tractor I tried it out on heavy clay soil. The cores didn't ********* the soil very well, so I added a wooden crate to the top and added concrete paving slabs until it reached the desired ***********. It's best to do it when the soil is wet, but not soggy. I have aerated about 10 acres of pasture and it stood up very well. I would recommend this aerator
