8TEN LawnRAZOR 18" High-Lift Mower Blades for Toro 27-0990 3-Pack — OEM Fit, Heavy-Duty

The 8TEN LawnRAZOR high-lift replacement blade is a direct-fit, heavy-duty 18" mower blade made to restore lift and cutting performance on Toro and compatible decks (sold as a 3-pack).

When your mower's discharge and bagging performance drops, worn or damaged blades are a common cause. This 8TEN LawnRAZOR set replaces the OEM-style high-lift blades used on many Toro Z Master, TimeCutter and other commercial-style 52" decks. Each blade is manufactured to the same key dimensions as the original parts so you can reinstall with minimal fuss and regain consistent cutting height, improved clippings uplift, and better bag fill.

Which machines and part numbers will these blades fit?

These LawnRAZOR blades are engineered to match several OEM part numbers and popular 52" mower decks. Confirm fit by checking your mower's blade length, center hole, and thickness before ordering.

• Fits OEM references like Toro 27-0990, 56-2390 and variants
• Compatible with Lesco 050575 and Grasshopper 27-0990
• Designed for Toro Z Master and TimeCutter 52" decks (Z100, Z17-52, Z18-52, 17-52ZX, 18-52ZX)
• Verify center hole 1/2" and blade dimensions prior to installation

How do these blades affect cutting and bagging performance?

Because they are high-lift blades with the same shape and centers as the originals, these replacements restore the airflow pattern under the deck. Expect more consistent grass lift into the cutting plane, better bagging efficiency, and fewer clumps left behind when mowing dense turf.

• High-lift profile improves suction for clippings
• Sharper, uniform cutting edge reduces tearing and fraying
• Consistent deck balance minimizes vibration
• Blade thickness and length match OEM specs for reliable performance

What are the physical specifications and installation notes?

Each 8TEN LawnRAZOR blade measures 18" long and 2.5" wide, with a center hole of 1/2" and a thickness of 0.197". Installation follows the same steps as OEM blades—remove the spindle nut, note blade orientation, replace with the new blade, torque to the manufacturer's spec, and check blade clearance before use.

• Blade length: 18", width: 2.5"
• Center hole diameter: 1/2"; thickness: 0.197"
• Sold as a pack of three identical high-lift blades
• Always use proper torque and safety gear during replacement

How long will these blades last and how should I care for them?

Longevity depends on terrain and use: clean, sharpen, and inspect blades regularly. Replacing a full set when you notice uneven cuts, excessive vibration, or bent edges will keep your deck functioning at peak capacity.

• Sharpen as needed for crisp cuts—avoid aggressive metal removal
• Check for bends or nicks after striking debris; replace if damaged
• Keep blades balanced to prevent spindle wear and vibration
• Store spare blades in a dry place to prevent rust

Who is this for: This 3-pack of 8TEN LawnRAZOR high-lift replacement blades is ideal for homeowners and lawn-care professionals who maintain Toro Z Master or TimeCutter 52" decks and want a reliable, OEM-dimension replacement. It's a practical choice for anyone needing to restore bagging efficiency and uniform cutting without modifying their mower.
