8TEN LawnRAZOR Blade Set for Exmark Toro Lazer Z Turf Tracer Pioneer 52" 103-6402-S 109-6873 (Notched High Lift) 3 Pack

What It Is

This is a 3-pack of notched high-lift blades for 52-inch Exmark and Toro zero-turn mowers (Lazer Z, Turf Tracer, Pioneer). They’re designed for maximum grass lift and bagging performance in high-volume mowing.

Fitment & Compatibility

• Deck size: Fits 52-inch cutting decks only. Measure your deck width before buying.
• Models: Exmark Lazer Z, Turf Tracer, Pioneer; Toro TimeCutter, Z Master, Groundsmaster (52" decks). Check your owner’s manual for OEM part numbers 103-6402-S or 109-6873.
• Aftermarket: 8TEN replacement for OEM blades—same dimensions and notch pattern. Not a direct OEM part, but fits as a drop-in.
• Measurements: Blade length ~17.75 inches, center hole 7/8-inch, thickness ~0.25 inches. Confirm these match your current blades.

Key Things to Know

• Installation: Easy swap with a socket wrench and torque to ~70–90 ft-lbs. Center bolt is standard 5/8-inch.
• Lift: High-lift design creates strong suction—great for bagging but may throw debris in dusty/dry conditions.
• Durability: 8TEN blades are heat-treated steel, but may dull faster than OEM on rocky terrain. Check sharpness every 10 hours.
• Not for mulching: Notched high-lift blades are for side-discharge or bagging, not mulching decks. Using them for mulching will leave clumps.

Should You Buy It

If you have a 52-inch Exmark or Toro zero-turn and need reliable, affordable replacement blades for bagging or side-discharge, this 3-pack delivers solid performance at a lower price than OEM. Avoid if you mulch or mow over debris-heavy areas.
