What It Is

This is a 3-pack of mulching blades designed to fit 60-inch cutting decks on select Toro, Bad Boy, and Exmark zero-turn mowers. They replace OEM part numbers 105-7718, 105-7777, 105-8777, 115-9649, 038-6050-00, and 038-6060-00. Use them if you want finer clippings that decompose quickly and don’t require bagging.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Only for 60-inch decks. Measure your deck width or check your model’s spec sheet.
• Model compatibility: Fits Toro TimeCutter SS/Z Master/Grand Stand, Titan HD 1500, and Exmark Lazer Z. Also fits Bad Boy mowers with a 60-inch deck using the listed OEM numbers. Not for 48-inch or 54-inch decks.
• OEM vs aftermarket: These are direct replacements for the OEM part numbers listed. Confirm your current blade’s part number matches one of the six listed—they are not universal.
• Blade dimensions: Each blade is approximately 20.5 inches long with a 1-inch center hole and a 1/4-inch offset. Measure your existing blade if unsure.

Key Things to Know

• Mulching vs standard: These have a higher lift and more curved surface than standard blades. They chop clippings finer but can bog down in tall, wet grass. Mow when grass is dry.
• Installation: Swap one at a time. Use a torque wrench—tighten to 70–90 ft-lbs. Always wear gloves; the edges are sharp.
• Quality check: Made from hardened steel with a coated finish. They hold an edge well but will dull faster than standard blades if you mow over rocks or gravel. Sharpen or replace every 25 hours of use.
• Common gotcha: The center hole is 1 inch, but some older Toro spindles use a 5/8-inch hole. Measure your spindle before buying—these won’t fit without an adapter.

Should You Buy It

Buy this if you have a 60-inch Toro, Bad Boy, or Exmark zero-turn and want a cleaner, more finished look without bagging. It’s a solid value for a 3-pack at this price, but only if your deck spindle matches the 1-inch center hole. Skip it if you mow wet or overgrown grass frequently—standard blades will handle that better.
