103-6402 Blades Fit for 52" Exmark Lazer Z HP Turf Tracer Metro HP Toro 42 Mower Deck Replaces 103-6382 103-6402-S 109-6873 Notched High Lift (6 Pack)

What It Is

This 6-pack of notched high-lift blades is designed for 52-inch Exmark Lazer Z HP, Turf Tracer, and Metro HP mowers, plus Toro 42-inch decks. They replace OEM part numbers 103-6382, 103-6402-S, and 109-6873, and are intended for heavy-duty commercial cutting where superior grass lift and discharge are needed.

Fitment & Compatibility

Before buying, measure your deck width—this set fits 52" Exmark decks and 42" Toro decks, not all models. Verify your mower’s model number against Exmark Lazer Z HP, Turf Tracer, or Metro HP (e.g., LZHP52, TT52, MHP52). For Toro, confirm it’s a 42" deck (e.g., TimeCutter 4225, but check deck code). Measure blade length: these are 16.5 inches long, with a 5/8-inch center hole and 1-inch notch diameter. Do not assume fitment for older Exmark or Toro models—cross-check your OEM blade part number (103-6382, 103-6402-S, 109-6873) before purchase.

Key Things to Know

• High-lift blades increase airflow for better bagging or side discharge but can strain the engine on wet grass or low-horsepower decks.
• Installation is straightforward: remove the old blade, note the notch orientation (facing up toward the deck), and torque to 70-90 ft-lbs. Use a blade removal tool to avoid pinching fingers.
• Balance check is critical—unbalanced blades cause vibration and uneven cuts. Use a blade balancer after installation.
• 6-pack value saves money vs. buying singles, but only if you need all six (e.g., for a commercial fleet or multiple machines). If you only need one or two, look for smaller packs.

Should You Buy It

Buy this if you own a compatible 52" Exmark or 42" Toro mower and need a reliable, high-lift blade for dense or tall grass, especially with bagging or discharge setups. The 6-pack is cost-effective for commercial operators or those with multiple machines, but confirm your deck model and blade measurements first to avoid returns.
