Aerating your lawn with Brinly’s 40” Tow-Behind Spike Aerators loosens soil and permits seed, fertilizer, and water to reach roots. Featuring a rugged gunmetal-tone finish, the all-steel design includes 10 3D steel tines in galvanized steel that perforate the ground over 2" in depth. The innovative 3D shape, with over 12 razor-sharp tips per star, is tested to be two times stronger than flat tines and resists bending, even in compacted soil. Each 8” diameter star also rotates independently and continues revolving during tractor turns, resulting in fewer passes due to missed areas. The 14-gauge steel weight tray allows for up to 110 lbs. of additional weight to be added for maximum penetration in harder soils. The more you 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.
