Agri-Fab 40 In Tow Behind Lawn Plug Aerator with 24 Galvanized Coring Knives and Universal Hitch

What It Is

The Agri-Fab 40-inch tow-behind plug aerator uses 24 galvanized steel coring knives to pull soil plugs from lawns, reducing compaction and improving water/air flow. It’s designed for use with riding lawn tractors, garden tractors, or ATVs on medium to large residential lawns (½ acre or more).

Fitment & Compatibility

• Hitch: Universal clevis-style hitch fits most standard 3/4-inch or 1-inch hitch pins. Works with Category 0 or 1 sleeves. Not compatible with zero-turn mowers or quick-attach hitches without an adapter.
• Towing Vehicle: Requires a minimum 12–15 HP riding tractor or ATV with a 2-inch receiver or clevis hitch. Lighter lawn tractors (under 10 HP) may struggle on slopes or dense soil.
• Deck Clearance: The aerator is 40 inches wide. Ensure your towing vehicle’s rear deck doesn’t block the hitch or drag on turns. Measure from hitch point to rear tire edge—allow at least 6 inches of clearance.
• Weight: 95 lbs empty; add up to 40 lbs of weight (sand/water in included tray) for better penetration in hard soil. Verify your vehicle’s towing capacity exceeds 150 lbs.

Key Things to Know

• Assembly required: Takes 30–60 minutes with basic tools (wrenches, pliers). Instructions are clear, but check bolt tightness after first use.
• Depth adjustment: Manual pin adjusts knife depth from 0 to 3 inches. Set to 2–2.5 inches for most lawns; too deep can scalp uneven ground or damage irrigation heads.
• Common gotcha: The universal hitch may rattle or shift on non-standard receivers. Adding a hitch stabilizer or using a locking pin reduces noise and wear.
• Knife durability: Galvanized steel knives hold up well in loamy soil but may bend on rocky or root-heavy ground. Keep a spare set on hand for tough conditions.

Should You Buy It

Best for DIY homeowners with a riding tractor and a large, compacted lawn who want a budget-friendly plug aerator without renting equipment. Skip it if you have a zero-turn mower, a very small yard, or rocky soil where steel knives will dull quickly.
