Why is my aerator punching holes instead of pulling plugs?
When the soil is extremely compacted or moisture levels are off, aerators tend to punch solid holes without releasing plugs, which actually compacts the ground tighter instead of removing material. This leaves people unable to properly loosen their turf and forces them to guess whether the issue is soil density or equipment failure.
