What It Is

This is a set of three aftermarket mulching blades designed to replace OEM blades on commercial zero-turn mowers with a 52-inch cutting deck. They are intended for mulching grass clippings into fine particles to return nutrients to the lawn.

Fitment & Compatibility

Before buying, confirm these three critical points:

• Deck size: This set is for 52-inch decks only. Measure your deck width if unsure.
• Blade measurements: Each blade is approximately 18 inches long, 2.5 inches wide, with a 5-point star center hole. Compare to your current blades.
• Model compatibility: Replaces Scag A48108, 48108, 481707, 481711, 48185; Exmark 103-2508; Husqvarna 539100341. Compatible with Ariens Zoom 2252, Gravely Promaster 152Z, and many other 52-inch commercial zero-turn mowers. Check your owner’s manual for exact OEM part numbers.

Key Things to Know

• Quality: Aftermarket blades – check sharpness and balance out of the box. Some users report they are slightly thinner than OEM blades, which may reduce lifespan on heavy-duty commercial use.
• Installation: Requires basic tools (socket wrench and torque wrench). Always torque to manufacturer specs (typically 70-90 ft-lbs) and use a blade removal tool to prevent spinning.
• Mulching vs. bagging: These are dedicated mulching blades – they will not provide good lift for bagging or side-discharge. If you switch modes, keep a separate set of standard blades.
• Common gotcha: Ensure the star center hole matches your spindle’s drive hub. Some Husqvarna and Exmark models use a different center hole pattern – measure yours before ordering.

Should You Buy It

If you own a 52-inch commercial zero-turn mower from Scag, Exmark, Husqvarna, Ariens, or Gravely and primarily mulch clippings, this set offers solid value at $37.99. It is a good budget alternative to OEM blades for homeowners and light commercial users, but heavy-duty operators may prefer OEM for longer edge life.
