2PK Oregon 594-601 Gator Blades for Exmark 30" Commercial 30 S-Series ECS180CKA30000

What It Is

This is a two-pack of Oregon Gator G5 mulching blades (model 594-601) designed specifically for the Exmark 30-inch Commercial 30 S-Series (ECS180CKA30000). They use a multi-step cutting edge to shred clippings finer than standard blades, ideal for heavy mulching or bagging on commercial zero-turn mowers.

Fitment & Compatibility

Check before buying:

• Deck size: 30 inches (Exmark S-Series only – not for 36" or 48" decks).
• OEM number: Replaces Exmark 112-0299-00 or 112-0299-01. Verify your current blade part number.
• Measurements: Length 16.5", width 2.25", center hole 0.5", offset 0.5". Measure your old blade to confirm.
• Model specificity: Fits Exmark 30" Commercial 30 S-Series with ECS180CKA30000 serial prefix. Does not fit older Lazer Z or turf models.
• Aftermarket note: Oregon is a reputable aftermarket brand – not OEM, but often matches or exceeds OEM quality. Confirm your spindle/hub accepts standard 0.5" center hole.

Key Things to Know

• Quality: Oregon Gator blades are heat-treated and coated for durability. Expect 2–3 seasons of commercial use before dulling.
• Installation: Medium difficulty. You’ll need a socket wrench and torque to 55–65 ft-lbs. Always re-torque after 1 hour of use.
• Common gotchas: The Gator serrated edge can be aggressive on thick grass – may require slower ground speed. Not for fine finish mowing (leaves a slightly ragged cut on delicate turf).
• Balance: New blades come pre-balanced, but always check with a balancer before installing to avoid vibration.

Should You Buy It

If you own the Exmark 30" Commercial 30 S-Series and need reliable, long-lasting mulching blades for daily commercial use, this is a solid value at $36.99 for a two-pack. It’s not for homeowners or for pristine lawn finish – but for heavy-duty mulching and bagging, it’s a proven upgrade over OEM. Skip if you need a fine cut or if your deck has a different spindle hole size.
