Aerators are quite heavy on their own, and with the added weights, they can weigh more than 200 pounds. Aerators need to be heavy to dig into the soil. However, towing a heavy lawn aerator can be difficult work. To reduce the effort used when aerating your lawn, make sure to properly water your lawns so that the soil is well moisturized. Moisturized soil is easier to dig than dry soil; thus, you won’t need as many weights, making your work easier.
