Oregon 6PK 595-605 G5 Gator Mulching Blades for Husqvarna Craftsman Poulan 187254 187256 21546235 532187254

What It Is

This Oregon 6PK 595-605 G5 Gator mulching blade set (6 blades total) is designed for 54-inch and 60-inch zero-turn mowers from Husqvarna, Craftsman, and Poulan Pro. The G5 Gator’s patented “gullet” teeth and serrated edge shred clippings finer for superior mulching, making it ideal for lawns where bagging is not preferred.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size and blade length: This set fits 54-inch and 60-inch decks. Each blade is 18.5 inches long, 2.5 inches wide, with a 5-point star center hole and 0.5-inch diameter.
• OEM cross-reference: Replaces Husqvarna/Craftsman/Poulan OEM part numbers 187254, 187256, 21546235, and 532187254. Check your current blade or owner’s manual for these numbers.
• Deck brand list: Confirmed fit on Husqvarna (e.g., Z242F, Z254), Craftsman (ZT 7000 series), and Poulan Pro (PPZ series) zero-turn mowers. Does not fit standard walk-behind or smaller riding mowers.

Key Things to Know

• Quality: Oregon blades are made from hardened boron steel and last 2-3x longer than OEM stamped blades under normal use. The G5 design reduces clumping in wet grass.
• Installation difficulty: Moderate. You’ll need a torque wrench (set to 70-90 ft-lbs). Blades are heavy and sharp—wear gloves. Always disconnect the spark plug and battery before lifting the deck.
• Common gotcha: The set includes six blades, but some 54-inch decks use three blades (left, center, right) and some 60-inch decks use two or three blades. Count your existing blades—this kit covers a six-blade setup (two per spindle on some models).
• Balance: Blades come pre-balanced out of the box, but you should re-check balance after sharpening or if you hit a rock.

Should You Buy It

Buy this if you own a compatible 54” or 60” zero-turn mower from Husqvarna, Craftsman, or Poulan Pro and want premium mulching performance with less bagging. It’s a solid upgrade over OEM blades for heavy-use lawns, but skip it if your deck uses a different mounting pattern or if you primarily bag grass (use high-lift blades instead).
