Oregon 6PK 596-322 Gator Blades for Exmark 52" Radius X-Series RAX691GKA524A3

What It Is

The Oregon 6PK 596-322 Gator Blades are a set of six aftermarket mulching blades designed for Exmark 52" Radius X-Series mowers (model RAX691GKA524A3). They use Oregon’s patented “Gator” wave-style cutting edge to improve mulching and bagging performance compared to standard flat blades.

Fitment & Compatibility

• Deck size: Only fits 52" Exmark decks. Measure your deck width before ordering—this is a 6-blade set, so each blade is roughly 18.5" long.
• Model check: Confirmed fit for Exmark Radius X-Series RAX691GKA524A3. Not compatible with older Exmark Lazer Z or other deck sizes.
• OEM vs aftermarket: These replace OEM Exmark blades (part numbers 116-2608, 116-2609, or 116-2610). Check your current blade part number or measure center hole diameter (must be 5/8") and overall length.
• Blade pattern: Set includes three straight and three curved blades (alternating positions). Verify your deck requires this pattern—some Exmark decks use identical blades on all spindles.

Key Things to Know

• Installation: Moderate difficulty. You’ll need a torque wrench (set to 70-80 ft-lbs) and a blade removal tool. Mark blade positions before removal—mixing up straight vs curved blades will cause vibration.
• Mulching quality: The Gator wave design creates finer clippings than OEM flat blades, but may reduce lift in wet or tall grass. Expect better mulching, slightly worse vacuum.
• Durability: Oregon uses heat-treated steel. These last 2-3 seasons on residential use with regular sharpening, but dull faster than OEM if you hit rocks or roots.
• Balance: Each blade is individually balanced from the factory, but check with a blade balancer after sharpening to avoid deck vibration.

Should You Buy It

Buy these if you want improved mulching on your Exmark 52" Radius X-Series and are comfortable with a 6-blade installation. They’re a solid aftermarket upgrade over OEM flat blades, especially for homeowners who prioritize fine clippings over raw power in tall grass. Skip them if you need maximum bagging performance or have a different deck size.
