Agri-Fab 45-0544 40 inch Tow Behind Spike Aerator for Aerating Lawns; 10 Galvanized Steel Spike Disks, Universal Hitch, Black

What It Is

The Agri-Fab 45-0544 is a tow-behind spike aerator designed for medium-to-large lawns (up to 1 acre). It uses 10 galvanized steel spike disks to punch holes in soil, improving water and air flow. It works with most riding lawn mowers, garden tractors, and ATVs/UTVs that have a standard hitch.

Fitment & Compatibility

• Hitch type: Requires a standard 1-7/8-inch or 2-inch hitch ball (not included). No special adapter needed for most lawn tractors.
• Deck clearance: Ensure your mower’s deck or rear tire doesn’t interfere with the aerator frame. Measure 40 inches wide and about 18 inches from hitch to first spike disk.
• Towing capacity: Your vehicle must handle ~60 lbs empty (adds weight when filled with water or sand). Check your owner’s manual for max tow weight.
• Universal fit: Works with John Deere, Cub Cadet, Husqvarna, Craftsman, Troy-Bilt, and similar brands with a rear hitch. Not for zero-turn mowers without a hitch kit.

Key Things to Know

• Assembly required: You’ll need basic tools (wrenches, socket set). Expect 30–60 minutes. Instructions are clear but small parts can be easy to lose.
• Weight matters: The aerator works best with added weight (fill the hopper with water or sand). Without it, spikes may not penetrate hard or dry soil.
• Spike vs. core aeration: Spikes can compact soil edges around holes, so it’s less effective than plug aerators on heavy clay. Best for routine maintenance, not fixing severe compaction.
• Rust risk: Galvanized steel resists corrosion, but if you leave it outside in rain, the hitch pin and bolts may rust. Store indoors or oil moving parts.

Should You Buy It

Buy this if you have a 1/2–1 acre lawn with loamy or sandy soil and want a budget-friendly way to aerate annually. It’s easy to tow, stores upright, and does the job for light-to-moderate aeration. Skip it if you have heavy clay, compacted lawns, or need deep core aeration—you’ll get better results from a plug aerator.
