Oregon 93-011 Heavy Duty Blades for 61" Spartan 438-0002-00

What It Is

The Oregon 93-011 is a set of three heavy-duty replacement blades designed for 61-inch zero-turn mower decks, specifically built for the Spartan 438-0002-00 model. These are aftermarket blades intended for commercial or heavy residential use.

Fitment & Compatibility

• Deck size: Only fits 61-inch mower decks. Measure your deck width to confirm.
• Brand/model: Directly replaces Spartan OEM blade part number 438-0002-00. Not compatible with other brands like John Deere, Toro, or Scag unless you verify measurements.
• OEM vs aftermarket: Oregon is a reputable aftermarket manufacturer, but these are not OEM Spartan blades. Check that your deck uses a three-blade spindle system.
• Measurements: Each blade is 0.204 inches thick, 2.25 inches wide, and 22 inches long. Verify these against your current blades—especially the center hole diameter (usually 5/8-inch) and bolt pattern.

Key Things to Know

• Quality: These are heavy-duty (0.204" vs standard 0.170") and last longer in abrasive or rocky conditions. They are not mulching or bagging blades—just standard lift.
• Installation: Requires basic tools (socket wrench, torque wrench). Install with the lift wings pointing up toward the deck. Torque spindle bolts to 70-90 ft-lbs. Use thread locker if not pre-applied.
• Gotchas: The set includes three blades, but some 61-inch decks use two blades—count yours before buying. Also, these are not coated, so they will rust if stored wet.
• Balance: Out of the box, they may need balancing. Use a blade balancer to avoid vibration and spindle wear.

Should You Buy It

Buy these if you own a Spartan 61-inch zero-turn (model 438-0002-00) and need longer-lasting blades for thick grass or debris. Avoid if you need mulching blades or have a different deck size—stick with OEM or verify measurements first.
