(6) Toothed Mulching Mower Blades for Scag Zero Turn 61" Deck Replaces 483318

What It Is

This is a set of six toothed mulching blades designed for Scag zero-turn mowers with a 61-inch cutting deck. They replace OEM part number 483318 and are intended for operators who want finer grass clipping mulching rather than side discharge or bagging.

Fitment & Compatibility

• Deck size: Only fits Scag 61-inch decks. Do not use on 48-, 52-, or 72-inch decks.
• Model fit: Fits Scag Turf Tiger, Cheetah, Wildcat, and Patriot models with the 61" deck. Check your mower’s serial number against Scag’s compatibility list.
• OEM cross-reference: Replaces Scag part 483318. Aftermarket blades may vary slightly in thickness or balance—measure your OEM blade’s center hole diameter (typically 1-inch) and overall length (approximately 20.5 inches) to confirm.
• What to verify before purchase: Measure your current blade length, center hole size, and the number of blades required (6). Also check that your deck has the mulching baffle kit installed—these blades will not mulch effectively without it.

Key Things to Know

• Quality: Aftermarket toothed blades can dull faster than OEM equivalents, especially in sandy or rocky soil. Expect to sharpen or replace more frequently.
• Installation difficulty: Moderate. You’ll need a torque wrench and blade removal tool. Torque to manufacturer specs (typically 70-90 ft-lbs). Always replace blades in sets of six to maintain balance.
• Common gotchas: The toothed design can clog in wet, thick grass—only use in dry conditions. These blades may also produce more vibration if not balanced after installation. Check balance with a blade balancer before mounting.
• Fitment note: Some users report the toothed blades sit slightly differently in the spindle hub. Test spin by hand after installation to ensure no contact with deck housing.

Should You Buy It

If you own a Scag 61-inch zero-turn and want a budget-friendly mulching upgrade for dry, well-maintained lawns, this set is a solid value. But if you mow wet grass, need OEM durability, or don’t have the mulching baffle kit, stick with standard Scag blades.
