2PK Oregon 594-601 G5 Gator Blades for 30" Exmark 116-6358-03, 116-6358-S

What It Is

This is a 2-pack of Oregon G5 Gator mulching blades (model 594-601) designed for 30-inch Exmark mower decks, specifically replacing OEM parts 116-6358-03 and 116-6358-S. These blades are for heavy mulching and fine grass clipping shredding.

Fitment & Compatibility

• Deck size: Fits 30-inch Exmark decks only (e.g., Exmark Quest, Lazer Z models with 30" cutting width). Not for 36" or larger decks.
• OEM cross: Replaces Exmark 116-6358-03 and 116-6358-S. Confirm your mower uses these part numbers.
• Measurements: Blade length is 15 inches (center hole to tip), center hole diameter is 1 inch (standard for most Exmark spindles). Check your current blade length and hole size before ordering.
• Aftermarket fit: Oregon G5 is a direct replacement—no adapter or modification needed. Double-check your mower’s spindle bolt size (usually 5/16" or 3/8") to ensure bolt fits through blade hole.

Key Things to Know

• Mulching performance: G5 Gator blades have serrated edges and curved fins for fine shredding, but they are not lift blades—they don’t discharge well. Use only for mulching, not bagging or side-discharge.
• Installation: Easy swap with a socket wrench and torque to 70-80 ft-lbs. Ensure blades are oriented with fins pointing upward (toward deck). Sharp edges—wear gloves.
• Durability: Oregon blades are heat-treated and last 25-50 hours of normal use. Check for bending if hitting rocks or roots; replace immediately if damaged.
• Common gotcha: These blades are heavier than OEM—may slightly increase vibration if your deck is unbalanced. Re-balance spindle if needed.

Should You Buy It

Buy this if you own a 30-inch Exmark mower and primarily mulch leaves or thick grass. It’s a solid upgrade over standard blades for finer clippings, but skip if you need bagging or side-discharge. The price is fair for a 2-pack, though reviews are sparse—reliable for residential use.
