Brinly Tow Behind Spike Aerator with Double Tow Bar and 3D Steel Tines, 40" - Textured Black

What It Is

This is a 40-inch wide, tow-behind spike aerator designed for use with lawn tractors and zero-turn mowers. It pokes holes into compacted soil to improve air, water, and nutrient flow, making it ideal for medium to large lawns (½ acre and up).

Fitment & Compatibility

• Hitch type: Requires a standard 2-inch (Class II) receiver hitch on your tractor or mower. Does not work with sleeve hitches or smaller lawn tractor pin-style hitches.
• Tractor size: Best for machines with at least 15 HP and a 42-inch or larger deck. Underpowered tractors may struggle on slopes or thick turf.
• Weight limit: The unit weighs about 60 lbs; ensure your tow vehicle can handle the tongue weight and pulling load.
• Deck clearance: The double tow bar extends 18 inches behind the hitch. Measure that your mower deck won’t contact the aerator frame when turning.
• Brand compatibility: Works with most major brands (John Deere, Husqvarna, Cub Cadet, etc.) as long as they have a Class II receiver. No OEM-specific adapters needed.

Key Things to Know

• Assembly required: Takes about 30–45 minutes with basic hand tools (wrenches, socket set). Instructions are clear but check that all bolts are tight before first use.
• Spike vs. core aeration: Spikes poke holes but can compact soil around the holes. For clay-heavy lawns, a core aerator is more effective. This is best for sandy loam or already aerated lawns.
• Weight plates: The unit has no built-in weight tray. On dry/hard soil, you may need to add cinder blocks or sandbags (not included) for deeper penetration.
• Tine durability: The 3D steel tines are strong but can bend if you hit large rocks or tree roots. Inspect the area before aerating.
• Coverage: At 40 inches wide, it covers a typical 10,000 sq ft lawn in about 15–20 passes. Works best at slow speed (2–3 mph).

Should You Buy It

Buy this if you have a lawn tractor with a Class II hitch, a lawn larger than ½ acre, and occasional soil compaction issues that you want to fix cheaply without renting equipment. Skip it if you have heavy clay soil (needs core aeration) or a small yard where a manual aerator or walk-behind unit makes more sense.
