8TEN LawnRAZOR Mower Blade for Exmark Toro P21 Trim 21 inch Deck 108-3762-S 108-3762-03 108-0954-03 (High Lift) 2 Pack

What It Is

This is a high-lift replacement blade set (2-pack) designed for 21-inch walk-behind mowers, specifically engineered to improve grass clipping discharge and bagging performance on Toro and Exmark models with a P21 Trim deck.

Fitment & Compatibility

• Deck size: 21-inch cutting deck only—do not use on larger or smaller decks.
• OEM cross-reference: Replaces Toro/Exmark part numbers 108-3762-S, 108-3762-03, and 108-0954-03.
• Mower models: Fits Toro TimeCutter, Super Recycler, Recycler, and Exmark Lazer Z, Quest, and Turf Tracer models equipped with the P21 Trim deck. Confirm your mower’s deck model before ordering—check the deck sticker or manual.
• Measurements: Blade length is approximately 21 inches, center hole diameter is 1 inch, and the drive pin hole is 7/16 inch. Verify your spindle’s pin pattern matches.
• Aftermarket note: This is an aftermarket blade—performance and balance may vary slightly from OEM, but it’s a direct fit replacement for the listed OEM numbers.

Key Things to Know

• High lift design: Produces strong airflow for superior bagging and side discharge, but creates more drag—expect a slight power draw and more noise compared to standard blades.
• Installation: Straightforward swap with basic hand tools (socket wrench, torque wrench recommended). Torque blade bolt to 55-65 ft-lbs. Use a blade balancer after installation to avoid vibration.
• Common gotcha: Ensure your mower’s spindle is compatible with a high-lift blade—some low-horsepower mowers may struggle with the added load, especially in tall or wet grass.
• Durability: Heat-treated steel holds an edge well for residential use, but may dull faster with frequent contact with gravel or roots. Sharpen or replace annually.

Should You Buy It

Buy this if you have a Toro or Exmark 21-inch P21 deck mower and want improved bagging or discharge performance without paying OEM prices. It’s a solid value for residential users who cut weekly and prioritize clean clippings. Skip it if you need a mulching blade or have a low-power mower that struggles with high-lift blades.
