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 Aerators loosens soil and permits seed, fertilizer, and water to reach roots. Our durable, heavy-duty aerator features 10 3D stars in galvanized steel. Their 3D design doubles the strength and perforates the ground over 2.5” deep, even in hard soil. 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. The more you spike aerate, the better your lawn looks and feels. Brinly aerators offer homeowners durable, high performance and affordable ways to aerate any size lawn, all from the comfort of your riding mower or ZTR.
