Rotary 52" 11495 High Lift Lawnmower Blade Set Exmark 103-6402 Toro 109-6873-03

What It Is

This is a set of three high-lift lawn mower blades designed for 52-inch zero-turn mowers. They are aftermarket replacements for Exmark (103-6402) and Toro (109-6873-03) OEM blades, intended for heavy-duty cutting and improved grass discharge in high-volume or wet conditions.

Fitment & Compatibility

• Deck size: Only for 52-inch cutting decks. Measure your deck width to confirm.
• Model/brand fit: Direct fit for Exmark Lazer Z, Turf Tracer, and Toro TimeCutter, Titan, Z Master, and Groundsmaster models using the OEM numbers listed. Check your owner’s manual for exact OEM part number.
• OEM vs aftermarket: Aftermarket replacement—not OEM Toro/Exmark. Confirm blade length, width, and center hole size are identical to your originals (typically 0.625-inch center hole, 18.5-inch length).
• Measurements: Each blade is approximately 18.5" long, 2.5" wide, 0.203" thick with a 0.625" center hole. Verify these against your current blade before ordering.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and blade removal tool. Torque bolts to 70-80 ft-lbs. Use thread locker if not factory-lubed.
• Quality: High-lift design increases airflow for better bagging and side discharge, but creates more drag. May reduce engine RPM in thick grass; ensure your mower has adequate horsepower.
• Common gotchas: High-lift blades wear faster than standard or mulching blades, especially in sandy soil. Check and sharpen every 10-15 hours of use. Not suitable for mulching—they are designed for discharge or bagging only.
• Balance: Aftermarket blades can vary in balance. Spin-check on a blade balancer after installation to avoid vibration and spindle damage.

Should You Buy It

Buy this set if you need an affordable, direct-fit replacement for high-lift blades on a 52-inch Exmark or Toro zero-turn used for bagging or side-discharge mowing. It’s a solid value versus OEM, but skip it if you need mulching blades or your deck requires a different blade length/center hole size.
