King Kutter Rotary Cutter Blades for 5', Code 501124, Set of 2

What It Is

This is a set of two replacement rotary cutter blades for 5-foot (60-inch) King Kutter or compatible brush hogs and finish mowers. Designed for heavy-duty cutting of grass, weeds, and light brush, these blades are intended for tractors or dedicated rotary cutters in agricultural or property maintenance use.

Fitment & Compatibility

Before buying, confirm your deck’s blade hole pattern and dimensions. These blades are a direct OEM replacement for King Kutter models with a 60-inch cutting width (code 501124). Measure your existing blades: center hole diameter (commonly 1 inch), bolt hole size (often 5/8 inch), and overall length (typically 29-1/2 inches). Verify the blade offset (flat vs. dished) matches your deck’s spindle orientation. They fit most 5-foot King Kutter rotary cutters from the 1990s onward, but non-King Kutter brands (e.g., Bush Hog, Land Pride) require checking hole spacing and thickness (these are 0.25-inch thick). Always compare to your old blade’s part number or physical specs—don’t rely solely on deck size.

Key Things to Know

• Material & durability: Made from heat-treated, high-carbon steel for impact resistance; sharpening is possible but limited due to hardening.
• Installation difficulty: Moderate—requires a breaker bar or impact wrench for stuck bolts; use anti-seize on hardware to prevent future corrosion.
• Common gotcha: These blades are sold as a matched set, but some decks use two different blade types (e.g., one suction, one lift). Check if your original blades are identical; if not, you may need a different set.
• Safety: Always disconnect the spark plug and block the blade before removal; wear gloves to avoid cuts.

Should You Buy It

This is a solid, budget-friendly choice for King Kutter owners needing a direct OEM replacement with proven durability (4.6 stars). Avoid if your cutter requires non-standard hole patterns or if you need blades for lighter-duty finish mowing—these are built for medium brush, not manicured lawns.
