MowerPartsGroup (3) Reaper 52" HD Toothed Mulching Blades for Scag Gravely Toro Made in USA

What It Is

This is a set of three heavy-duty toothed mulching blades designed for 52-inch zero-turn mowers from Scag, Gravely, and Toro. They are built for commercial-grade grass cutting and fine mulching, with a focus on durability and lift.

Fitment & Compatibility

Before buying, verify three things: deck size (must be 52"), blade length (measure your current blade from center hole to tip—typically 18-19 inches on these models), and center hole diameter (usually 5/8" or 7/8"). These are aftermarket blades, not OEM Toro/Scag/Gravely parts, so check that your deck uses a three-blade spindle pattern. Common compatible models include Toro Z-Master 7000/8000, Scag Turf Tiger, and Gravely Pro-Turn 52. If your deck uses a different bolt pattern or blade offset, they won’t fit. Measure your existing blade’s thickness too—these are 0.25" thick, so thinner OEM blades may require different hardware.

Key Things to Know

• Made in USA – high-quality steel with heat-treated cutting edges; last longer than standard stamped blades.
• Installation is straightforward – remove old blades, clean spindles, torque bolts to spec (usually 70-90 ft-lbs). No special tools needed.
• Mulching performance is excellent – the toothed design chops clippings fine, but they won’t bag or side-discharge as well. Best for mulching-only use.
• Balance check recommended – aftermarket blades can sometimes be slightly off-balance; use a blade balancer before installing to avoid vibration.

Should You Buy It

If you own a 52" zero-turn from Toro, Scag, or Gravely and want a tough, long-lasting mulching blade that handles heavy grass without clogging, this is a solid buy. It’s not for bagging or side-discharge use, and fitment is narrow—double-check your deck model before ordering. For commercial operators or homeowners who cut frequently and want less cleanup, it’s a great value.
