The Brinly-Hardy SA2-40BH-S is a 40-inch tow-behind spike aerator that pulls behind a riding mower or zero-turn tractor. It uses 10 independently rotating star-shaped steel tines with over 12 sharp points each, punching more than 2 inches into the soil. A 14-gauge steel tray holds up to 110 lbs of added weight for harder, compacted ground. It suits homeowners with a larger lawn and a riding mower who want to aerate without renting equipment or hiring a service, and it costs far less than a plug aerator or a pro aeration visit.

Owners of tow-behind Brinly aerators generally report solid steel construction and tines that hold up in tough soil. Many say adding weight makes a clear difference in penetration. Some note that spike tines leave smaller holes than core aerators and that very hard ground needs several passes.
The Brinly-Hardy 40" Tow-Behind Spike Aerator loosens soil so seed, fertilizer and water can reach the roots. It tows behind a riding mower or ZTR and has a gunmetal-tone finish.
The all-steel design has 10 galvanized steel 3D tines that perforate the ground more than 2" deep. Each 8" diameter star has over 12 sharp tips. The 3D shape is tested to be two times stronger than flat tines and resists bending in compacted soil.
Each star rotates independently and keeps turning during tractor turns, so fewer areas are missed. The 14-gauge steel weight tray holds up to 110 lbs. of additional weight for more penetration in harder soils.
