8TEN LawnRAZOR Mower Blade for Ferris Bobcat 5102227 574481401 112111-04 72 inch Deck (Medium Lift Notched) 3 Pack

What It Is

The 8TEN LawnRAZOR Mower Blade is a medium-lift, notched replacement blade for 72-inch Ferris Bobcat zero-turn mowers. It’s designed for high-production commercial mowing where bagging or side-discharge performance with heavy grass is needed.

Fitment & Compatibility

This 3-pack fits Ferris Bobcat models with a 72-inch deck, specifically replacing OEM part numbers 5102227, 574481401, and 112111-04. Before buying, measure your existing blade’s length (this blade is 20.5 inches end-to-end), center hole diameter (typically 1 inch), and thickness (0.25 inches). Verify the notched shape matches your spindle’s drive pin pattern—this blade uses a single notched center hole for a pin-drive system. It will not fit standard 5/8-inch round hole spindles. Check your deck’s blade rotation direction (usually clockwise when viewed from above) and confirm the blade’s medium lift matches your grass type and discharge system.

Key Things to Buy

• Quality vs OEM: At $56.95 per 3-pack, these are a budget-friendly alternative. Expect slightly less edge retention than OEM Ferris blades, but adequate for most commercial use.
• Installation: Straightforward bolt-on replacement. Use a torque wrench to 70-90 ft-lbs. The notched design ensures correct orientation—align the notch with the drive pin.
• Common gotchas: These blades are not for mulching or standard 72-inch decks without pin-drive spindles. The medium lift may produce less vacuum than high-lift OEM blades, so test bagging performance on wet grass. Balance each blade after installation (use a blade balancer) to avoid vibration.
• Durability: Heat-treated steel with a painted finish. They’ll dull faster on sandy or rocky terrain—expect replacement every 25-50 hours under heavy use.

Should You Buy It

Buy this if you own a Ferris/Bobcat zero-turn with a 72-inch pin-drive deck and want a solid, affordable 3-pack for regular mowing. It’s a good value for operators who don’t need top-tier OEM edge life and prefer replacing blades in batches. Skip it if you require OEM-spec durability for daily commercial cutting or if your deck uses a round-hole spindle.
