SA-40BH - 40" Spike Aerator

Compacted soil results in thatch buildup and reduces the amount of water and nutrients your grass receives. If your lawn experiences moderate foot traffic, suffers from a thatch layer of more than ½ inch, or if you have heavy clay soil, you may need to aerate. Aerating your lawn with Brinly’s 40” Tow-Behind Spike Aerator loosens soil and permits seed, fertilizer and water to reach roots.

Our durable, heavy-duty aerator features 10 galvanized steel stars that perforate the soil up to 2” deep. Each 8” diameter star rotates independently and continues revolving during tractor turns, resulting in fewer passes due to missed areas. The 14 gauge steel, 110 lb. capacity weight tray allows for additional weight to be added for maximum penetration in hard soil.
