Brinly Tow-Behind Spike Aerator 40" — Hammered Black, 2" Tine Depth & 110 lb Weight Tray

The Brinly SA2-40BH-P is a 40-inch tow-behind spike aerator that uses ten 8" galvanized 3‑D tine stars and a 110 lb weight tray to penetrate up to 2" into compacted lawn soil.

If your turf is showing signs of thatch buildup, poor drainage, or reduced vigor from foot traffic or heavy clay, this tow-behind aerator helps open the soil so water, seed, and nutrients reach grassroots. Built with an all-steel frame, galvanized rotating stars, and a double tow bar, the unit mounts behind most garden tractors to aerate larger yards quickly and with greater consistency than handheld tools.

How deep and how effectively does it penetrate compacted soil?

The SA2-40BH-P drives each of its 10 stars up to two inches into the ground, creating channels that improve air and moisture movement. The 8" diameter stars have 12 spikes each, designed to deliver repeated, evenly spaced perforations across a 40" working width.

• 2" maximum tine depth for improved water and nutrient access
• 10 rotating stars with 12 spikes per star for consistent coverage
• 8" star diameter spaces holes evenly across a 40" swath

What makes the 3-D tines and galvanized stars better than flat tines?

Brinly's patent-pending 3‑D tines are formed for increased rigidity and fatigue resistance compared with traditional flat spikes. Galvanized steel resists rusting, which extends tine life in wet or acidic soils and reduces bending in tough conditions.

• 3‑D tine geometry for roughly twice the strength vs. flat tines
• Galvanized finish to slow corrosion and reduce maintenance
• Individual star rotation keeps tines turning during turns for fewer missed spots

Can I adjust traction or penetration for hard soil?

The aerator includes a heavy-duty 14-gauge steel weight tray that accepts up to 110 pounds of ballast so you can increase downward force as soil conditions demand. A reinforced frame, 5/8" solid steel axle, and nylon spacers between stars provide long-term durability under added load.

• 110 lb capacity weight tray for added penetration in firm soil
• Double tow bar and reinforced side plates for towing stability
• Nylon spacers and solid axle reduce wear and keep stars aligned

How does this save time compared with push aerators or manual tools?

Towing the aerator behind a lawn tractor covers wide swaths quickly, and each star rotates independently so they keep working during turns and reduce missed areas. The 40" working width means fewer passes for medium to large lawns compared with narrow manual units.

• 40" working width reduces the number of passes needed
• Independently rotating stars continue spinning through turns
• Tow-behind design lets you aerate while using your tractor’s speed and traction

Who is this for: The Brinly SA2-40BH-P suits homeowners with medium to large lawns who own a garden tractor and need a durable, efficient way to relieve compaction, improve drainage, and help overseeding or fertilizing take root. It's a practical choice for yards with moderate foot traffic, clay soils, or thatch layers needing regular maintenance without renting commercial equipment.
