107-3192-03 107-3192 Mower Blade, Compatible with to-ro Commercial Walk Behinds Z Master G3 Grandstand Mowers, High Flow Toothed Blade Replace 110-0414 110-0418 3-Pack

What It Is

This is a high-flow toothed replacement blade designed for heavy-duty commercial Toro mowers, including walk-behinds, Z Master, and Grandstand models. It’s built for mulching or bagging in thick, wet, or tall grass where standard blades struggle.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: This blade fits 48-inch, 52-inch, and 60-inch Toro decks—but measure your blade length. The 107-3192 is approximately 20.5 inches long with a 1-inch center hole and 5/8-inch offset.
• Model series: Confirmed compatible with Toro Commercial Walk Behinds (e.g., 3000/4000 series), Z Master (e.g., Z4200, Z4500, Z4800), and Grandstand (e.g., 48″/52″ deck models). Check your model number against the OEM cross-references: 110-0414, 110-0418.
• OEM vs aftermarket: This is a non-OEM blade. It should fit, but tolerances may vary slightly. If you’ve had fitment issues with other aftermarket blades, measure the center hole and blade thickness (0.1875 inch) to be safe.

Key Things to Know

• Quality: Users report good durability and cutting performance in heavy grass, but with only one review, long-term wear data is thin. Expect similar life to OEM blades under normal use.
• Installation: Straightforward—remove the old blade, align the center hole, and torque the bolt to 65-75 ft-lbs. Use a blade removal tool to avoid stripping the bolt. No special adapters needed.
• Common gotcha: The toothed design creates more lift than standard blades. If your deck is prone to clogging in dry, light grass, this may make it worse. Best for wet or heavy conditions.
• Pack: You get three blades in one pack—good value vs buying OEM singles, but confirm you need three (most Toro decks use three blades).

Should You Buy It

If you run a Toro commercial mower and regularly cut thick, damp, or overgrown grass, this blade is a solid, cost-effective upgrade. It’s not ideal for light-duty residential use or dry, fine grass. Buy it if you want better mulching and lift in tough conditions and don’t mind an aftermarket part.
