What It Is

This is a 3-pack of toothed (mulching) replacement blades designed for 52-inch zero-turn mower decks. They fit popular commercial and residential brands including Ariens, Gravely, Husqvarna, Exmark, Scag, and Turf Tracer models.

Fitment & Compatibility

Before buying, confirm three things:

1. Deck size – Must be exactly 52 inches. Measure your deck width, not the blade length.
2. Blade dimensions – These blades are roughly 21 inches long with a 1-inch center hole and 7-gauge thickness. Measure your current blade’s length, center hole diameter, and thickness to verify.
3. Model compatibility – Direct replacements for OEM part numbers 00273100, 1-633482, 481707, 48108, and 481711. Fits popular models like Exmark Lazer Z, Scag Turf Tracer, Husqvarna Z5221, Gravely Pro-Master 152Z, and Ariens Zoom 52. Check your mower’s manual or existing blade part number to confirm.

Key Things to Know

• Mulching vs. bagging – The toothed design is optimized for mulching (fine clippings left on lawn). Not ideal for bagging or side-discharge use.
• Installation – Standard blade installation: lift deck, block securely, remove center bolt. Torque to 70-90 ft-lbs. No special tools needed.
• Balance – Aftermarket blades may need balancing. If you feel vibration after install, use a blade balancer ($10) to avoid deck damage.
• Sharpness out of box – Some users report they’re not razor-sharp; a quick file touch-up improves cut quality.

Should You Buy It

If you own a 52-inch zero-turn mower from the listed brands and mulch regularly, this is a solid, budget-friendly 3-pack. It’s a good value for the price, but verify your blade measurements and part number first to guarantee fit. Not for baggers or side-discharge setups.
