LawnRAZOR Blade for Cub Cadet MTD XT1-LT46 ZT1-46 46-Inch Deck 742-05510-L 742P05510-L 490-110-C199 Low Lift 2 Pack

What It Is

The LawnRAZOR blade is a low-lift replacement blade designed for 46-inch cutting decks on Cub Cadet and MTD lawn tractors and zero-turn mowers. It’s intended for standard residential mowing—especially in dry or light grass conditions—where minimal airflow and reduced suction help avoid scalping.

Fitment & Compatibility

Before buying, confirm your deck is exactly 46 inches (measured blade tip to tip). This blade replaces OEM part numbers 742-05510-L, 742P05510-L, and 490-110-C199. It fits Cub Cadet XT1-LT46 and ZT1-46 models, plus many MTD, Troy-Bilt, and Yard Machines tractors with a 46-inch deck. Check your blade’s center hole size (should be 1 inch) and overall length (approximately 20.5 inches). This is a low-lift blade—not compatible with high-lift or mulching-only decks. If your mower uses a different blade pattern (e.g., 3-in-1 with separate mulching plug), verify before purchase.

Key Things to Know

• Quality & durability: LawnRAZOR blades are heat-treated and hardened, typically lasting 2–3 seasons under normal use. They’re a solid aftermarket alternative to OEM, though some users report slightly thinner steel than factory Cub Cadet blades.
• Installation difficulty: Easy—requires a socket wrench and a blade removal tool (or a block of wood to prevent spinning). Torque bolts to 40–50 ft-lbs. No special adapters needed.
• Common gotchas: Low-lift blades produce less bagging suction and may leave clumps in wet or tall grass. They’re best for dry, flat lawns. Also, these are sold as a 2-pack, so you’ll need to buy two packs (4 blades total) for a 46-inch deck that uses 3 blades—check your deck’s blade count.
• Balance check: Always balance new blades after installation; LawnRAZOR blades are pre-balanced, but field reports note occasional slight imbalances. Use a simple blade balancer.

Should You Buy It

If you have a 46-inch Cub Cadet or MTD tractor/zero-turn and want a durable, affordable low-lift blade for routine dry-weather mowing, this is a strong buy. Skip it if you need high-lift performance for bagging or mulching in heavy grass—look for a dedicated high-lift or mulching blade instead.
