BGD 2 Pack 30" Deck Heavy Duty Mulching Blades, Fits Toro Exmark Walk-Behind Mowers, Replaces 120-9500-03 116-6358-03 120-9500 20120 20120P, Fits Toro 20199 20200 20975

What It Is

This is a 2-pack of heavy-duty mulching blades designed for 30-inch walk-behind mowers from Toro and Exmark. They replace OEM part numbers 120-9500-03, 116-6358-03, 120-9500, 20120, and 20120P, and are intended for users who want finer grass clippings and less bagging.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: These are specifically for 30-inch decks. Will not fit 21-inch, 36-inch, or larger decks.
• Model compatibility: Fits Toro models 20199, 20200, 20975, and Exmark walk-behinds using the same OEM blade pattern. Check your mower’s model number (usually on a sticker under the seat or on the deck).
• OEM cross-reference: The aftermarket blades match the listed OEM numbers exactly. If your mower uses a different blade pattern (e.g., 108-6148 or 131-1060), these will not work.
• Measurements: Each blade is approximately 15 inches long (for a 30-inch total), with a 1-inch center hole and a 7/16-inch offset. Verify your current blade matches these dimensions.

Key Things to Know

• Quality: Heavy-duty steel, but as an aftermarket product, edge retention may be slightly less than OEM Toro/Exmark blades. Expect moderate durability under normal residential use.
• Installation: Straightforward—remove the old blade, install with the air lift facing up, and torque the center bolt to 50-60 ft-lbs. Use thread locker if recommended by your mower manual.
• Common gotcha: These are mulching blades, not standard lift blades. They have a smaller air lift and more curved surface to recut clippings. If you need high-vacuum bagging or side discharge, these will not perform well.
• Balance: Aftermarket blades may require balancing before install. Use a blade balancer to avoid vibration and spindle wear.

Should You Buy It

If you own a 30-inch Toro or Exmark walk-behind and want a budget-friendly mulching blade upgrade for finer clippings, this pack offers solid value. But if you need OEM-level longevity or high-volume bagging, stick with genuine Toro/Exmark blades.
