SaidiCo 15.4" Blade for Exmark and Toro 30" Mowers Replaces # 116-6358-03 (2Pack)

What It Is

This is a 15.4-inch replacement blade set (2-pack) designed for 30-inch walk-behind mowers, specifically Exmark and Toro commercial models. It’s intended for side-discharge or mulching use, matching OEM part #116-6358-03.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 30 inches and requires 15.4-inch blades (center-to-center mounting holes). This blade fits Toro 30" mowers like the TurfMaster 30199, 30198, and ProLine 30187, plus Exmark 30" units (e.g., LZ30 series). Check your existing blade’s part number—this replaces Toro #116-6358-03 and Exmark #103-3023. Measure your blade length (not deck size) and verify the center hole diameter (typically 7/8" or 1") and thickness (usually 0.175"). Aftermarket: these are not OEM but match specs.

Key Things to Know

• Quality: Made from heat-treated steel; comparable to OEM in durability, but check edge hardness if you cut heavy grass or debris.
• Installation: Straight swap—remove old blade, clean spindle, torque to 70-90 ft-lbs. Use a blade lock or wedge to hold it.
• Gotcha: The 15.4" length is exact; if your deck needs 15.0" or 16.0", these won’t fit. Verify before ordering.
• Balance: Aftermarket blades may need balancing before install—use a blade balancer to avoid vibration.

Should You Buy It

Buy this if you own a Toro or Exmark 30" walk-behind and need a budget-friendly, functional replacement for OEM #116-6358-03. It’s a solid value for routine cutting, but if you demand premium steel or longest life, stick with OEM.
