(New) 116-6358-03 (2) OEM Original Toro 30" TIMEMASTER, TURFMASTER Atomic Blades fits 20199, 20200, 22200, ECKA30, ECS180CKA30000

What It Is

This is a set of two OEM Toro Atomic blades (part #116-6358-03) designed specifically for 30-inch TimeMaster and TurfMaster mowers. They use a unique “atomic” profile with angled cutting edges to improve grass lift and mulching performance on larger residential or light commercial lawns.

Fitment & Compatibility

Before buying, confirm your mower has a 30-inch cutting deck and is one of these models: 20199, 20200, 22200, ECKA30, or ECS180CKA30000. These are OEM Toro blades, not aftermarket, so fitment is exact—no adapter or modification needed. Measure your current blade length (should be about 15 inches center-to-center) and check that the center hole diameter matches (typically 1 inch). If your deck uses two separate blades (not a single long blade), this set is correct. Not compatible with 22-inch or 42-inch Toro decks.

Key Things to Know

• Installation is straightforward—just remove the old blade bolt, swap blades, and torque the bolt to 50-60 ft-lbs. No special tools beyond a socket wrench and a block of wood to hold the blade.
• Sharpness out of the box varies; some users report needing to sharpen the edges before first use for best cut quality.
• Atomic design improves vacuum but wears faster than standard flat blades, especially in sandy or rocky soil—expect to replace every 1-2 seasons with regular use.
• Balance is critical—always check blade balance after installation to avoid vibration and spindle damage. A simple blade balancer costs under $10.

Should You Buy It

If you own a 30-inch Toro TimeMaster or TurfMaster and want guaranteed OEM fitment with the factory-recommended atomic cutting geometry, this is the right choice. It’s ideal for mulching and bagging in thick grass, but if you prefer longer blade life or cut in very abrasive conditions, consider aftermarket hardened blades instead.
