8TEN LawnRAZOR Mower Blade for John Deere 60 inch Deck 1025R 1026R 1550 TCU15881 M128485 M131958 (High-Lift) 9 Pack

What It Is

The 8TEN LawnRAZOR Mower Blade (High-Lift) is a set of nine aftermarket blades designed for John Deere 60-inch cutting decks, specifically models like the 1025R, 1026R, and 1550. The high-lift profile creates stronger airflow to lift grass for a cleaner, more uniform cut, ideal for thick or tall grass conditions.

Fitment & Compatibility

Before buying, confirm your deck is a 60-inch model (not 54" or 72"). This blade replaces OEM part numbers TCU15881, M128485, and M131958. It fits John Deere 1025R, 1026R, and 1550 tractors with 60" decks, plus many other Deere models using those OEM numbers. Measure your existing blade: center hole diameter should be 1 inch, overall length 20.5 inches, and thickness 0.1875 inches. Verify the blade mount pattern—these use a standard 5-point star center hole. Not compatible with non-Deere decks or older Deere 60" decks with different spindle designs (e.g., 60" 7-Iron deck). If you have a different deck model, cross-reference your OEM part number with the listed replacements.

Key Things to Know

• Quality: Made from heat-treated boron steel for durability. Edge stays sharp longer than budget blades, but high-lift design increases wear on blade tips in sandy or rocky soil.
• Installation: Straightforward—remove old blade, install new one with the high-lift wing pointing up toward deck. Use a torque wrench; tighten to 70–90 ft-lbs. No special tools needed beyond a socket and breaker bar.
• Gotcha: High-lift blades require more engine power and may throw grass clumps if mulch kit is installed. Best for side-discharge use only. Also, the 9-pack is a bulk buy—unless you have multiple machines or expect heavy wear, consider a 3-pack first.
• Balance: Each blade is individually balanced, but always check balance after sharpening. Unbalanced blades cause vibration and spindle damage.

Should You Buy It

If you own a John Deere 1025R, 1026R, or 1550 with a 60-inch deck and need a reliable, sharp-cutting high-lift blade for thick grass or frequent mowing, this is a solid value. The 9-pack is overkill for most homeowners unless you plan to replace blades multiple times per season or share with a neighbor. For casual mowing, a standard-lift blade might be easier on your engine.
