CRAFTSMAN (CMXGZBF7124336), 36-Inch Tow Spike Tow Behind Spike Aerator for Aerating Lawns; 9 Galvanized Steel Disks, 90lbs Capacity Weight Tray for Better Aeration, Universal Hitch, Red

What It Is

The Craftsman CMXGZBF7124336 is a tow-behind spike aerator designed for use with lawn tractors, zero-turn mowers, or garden tractors. It uses 9 galvanized steel disks to punch holes in soil, reducing compaction and improving water/nutrient absorption for mid-to-large lawns (½ acre+).

Fitment & Compatibility

• Hitch type: Universal 3/4-inch hitch pin fits most lawn tractors and zero-turns with a standard 1-inch receiver tube. Check your mower’s hitch clearance—low-slung decks (e.g., riding mowers under 42 inches) may drag the frame on uneven ground.
• Weight capacity: The 90-lb weight tray is removable; adding weights (sandbags, bricks) increases penetration. Do not exceed 150 lbs total to avoid bending the frame.
• Deck size: Works best with tractors 38 inches and wider. Narrower decks may struggle to pull evenly, especially on slopes.
• OEM vs aftermarket: Direct from Craftsman; no aftermarket adapters needed unless your hitch is non-standard (e.g., some John Deere models with proprietary receivers).

Key Things to Know

• Quality: Galvanized steel disks resist rust but may bend if hitting large rocks or roots. Weight tray is painted steel—check for chipping after first season.
• Installation: Tool-free assembly (bolts and cotter pins) in about 20 minutes. No drilling required.
• Gotchas: Spike aerators don’t remove soil cores—they just punch holes. On heavy clay, the 90-lb tray may not be enough; add 40–50 lbs for deeper penetration. Not effective on hard-packed or extremely dry soil—water the lawn 1–2 days before.
• Maintenance: Lubricate the axle bearings annually; disks will need occasional straightening if hitting obstacles.

Should You Buy It

Buy this if you have a ½+ acre lawn with mild to moderate soil compaction, want a quick, no-fuss aeration method, and don’t mind adding extra weight for clay soils. Skip it if you need core aeration (plug removal) for heavy clay or have a small lawn where a walk-behind aerator is more practical.
