Plug Aerator Knife Compatible with Agri-Fab's 40-52 inch Tow Behind Lawn Plug Aerator Lawn Spike Aerator eavy Rolling Lawn (24924)

What It Is

This is a replacement plug aerator knife designed for Agri-Fab tow-behind aerators, specifically models with 40–52 inch working widths. It cuts soil cores (plugs) to relieve compaction in lawns, making it a wear-and-tear replacement part for heavy-use aerators.

Fitment & Compatibility

Before buying, confirm your aerator is an Agri-Fab model with a 40–52 inch deck (e.g., 45-0463, 45-0464, or similar). Measure the existing knife’s mounting hole spacing and blade thickness—this knife is for standard Agri-Fab plugger assemblies, not spike aerators or compact models. It is an aftermarket part, not OEM, so check that your machine uses the common 2-bolt pattern (approx. 3.5 inches center-to-center). If your aerator is a different brand (e.g., Yard Tuff, CountyLine), verify compatibility via manufacturer specs; Agri-Fab’s 40–52 inch series is the primary match.

Key Things to Know

• Quality vs. OEM: At $18.58, this is a budget-friendly alternative to Agri-Fab’s OEM knives (often $25+). Some users report slightly thinner steel, so it may wear faster on rocky or clay-heavy soil.
• Installation Difficulty: Easy—requires a wrench to remove two bolts, swap the knife, and retighten. No special tools needed.
• Common Gotcha: Ensure you replace all knives at the same time for even coring depth. Mixing old and new blades can cause uneven plugging.
• Heavy-Duty Use Warning: For large lawns (over 2 acres) or frequent aerating, consider spending more on a thicker, heat-treated blade to avoid bending.

Should You Buy It

This is a solid, low-cost choice for homeowners or light commercial users who need a quick replacement for a worn Agri-Fab aerator knife. It’s not ideal for rocky terrain or heavy-duty rental-style use—opt for OEM or a thicker aftermarket blade if durability is a top concern.
