About This Product

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 1/2 in. or if you have heavy clay soil, you may need to aerate. Aerating your lawn with Brinly's 40 in. Tow-Behind Spike Aerators loosens soil and permits seed, fertilize and water to reach roots. Our durable, heavy-duty aerator features 10 galvanized steel stars that perforate the soil up to 2 in. D. Each 8 in. Dia star rotates independently and continues revolving during tractor turns, resulting in fewer passes due to missed areas. The 14-Gauge steel, 110 lbs. 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 lawn tractor.


  • Aerate and relieve compacted soil: 10 aerating stars with 8 in. Dia feature 12 spike tips to penetrate soil up to 2 in. D, allowing water, seed and nutrients to reach the roots
  • NEW 3-D tines for 2X the strength: Brinly's patent-pending 3-D tines in galvanized steel inhibit rust and resist bending, even in compacted soil
  • Durable construction: features an all-steel design with reinforced side plates and 5/8 in. solid steel axle for extra strength, nylon spacers between each star deliver increased durability
  • Includes weight tray: rigid weight tray holds up to 110 lbs. of extra weight for maximum soil penetration and depth
  • Save time on the job: each 8 in. Dia star rotates independently and continues revolving during tractor turns, resulting in fewer passes due to missed areas

        great behind mower
        Had to add lots of weight and strap down. If you dont strap the pavers, they will bounce off. Did the trick for 5 acres.

          Straight lines only
          This was easy to assemble. If there is a rock under the grass the tines bend. It worked great when you go in a straight line, but as soon as you turn to go the other direction the end panels collapsed.

          Good concept needs minor modification
          Purchased a month ago, easy to assemble, easy to attach to ZTR mower. Used it for our almost 2 acre yard, and found the end caps had bent. Made the pictured modification, and works great!

          Good product
          I decided that it was time to start aeration on my lawn. I always use a de thacher in the spring but a landscaper came to look at doing some work and recommend aeration as well. This unit was fairly simple to assemble. Instructions were clear. I found the hardware fine. Once assembled, its very easy to move around prior to adding weight. Definitely wear protective gloves while assembling tines,they are sharp. I added2 standard concrete building blocks and hitched up to my tractor. Drove slowly and let it do its job.

          It works!
          Aerator works as advertised. I live near the coast so my soil is somewhat sandy. I fabricated fold up wheels that work really well. I just remove the wing nuts and wells fold back. Tip; wait until after it rains a lot. The spikes didn’t penetrate as I hoped until after it rained.

          Spiked aerator
          [This review was collected as part of a promotion.] This is my first time using a spiked aerator although I know it will get easier in the future I must say it made my lawn preparation this year a breeze compared to the past years. I am looking forward to getting more experienced with my new lawn equipment in the coming years.
