8TEN LawnRAZOR Mower Blade for Toro Walk Behind Mower Rear Bagger 21 inch Deck 62-7700 62-7700-03 (High Lift)

What It Is

The 8TEN LawnRAZOR is a high-lift replacement blade for Toro walk-behind mowers with a 21-inch rear-bagger deck. Its aggressive lift profile is designed to maximize grass clipping suction into the bag, making it ideal for mulching or bagging applications.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 21 inches (center pin to blade tip). This blade replaces Toro OEM part numbers 62-7700 and 62-7700-03. It fits select Toro models with rear baggers, including Super Recycler, Personal Pace, and TimeCutter walk-behinds—but always cross-reference your mower’s model number with the 62-7700 series. The blade measures 21 inches long, 2.5 inches wide, with a 0.25-inch thickness and a 7-point star center hole. It will not fit standard 5/8-inch or 1-inch round hole spindles.

Key Things to Know

• Quality concerns: With a 3.3/5 rating from only 17 reviews, some users report premature dulling or balance issues out of the box. Inspect and balance the blade before installation.
• Installation difficulty: Moderate. You’ll need a socket wrench to remove the center bolt, and a torque wrench to tighten to 50–60 ft-lbs. Always disconnect the spark plug first.
• Common gotcha: High-lift blades increase engine load and vibration. If your mower struggles or vibrates excessively, the blade may be unbalanced or your deck may need leveling.
• OEM vs aftermarket: This is a budget alternative to genuine Toro blades. Expect slightly shorter lifespan and less consistent sharpness out of the box.

Should You Buy It

This blade is a reasonable choice if you want a high-lift design for bagging on a tight budget and are comfortable checking balance and sharpening after a few uses. Skip it if you need long-term durability, low vibration, or have a standard 5/8-inch spindle—those require a different blade.
