759-3813 742P3003 High Lift Blades for 50" Deck, Compatible with MTD Troy-Bilt Cub Cad-et 359 Super GT Lawn Mower, 3 Pack

What It Is

This is a 3-pack of high-lift replacement blades (part numbers 759-3813 and 742P3003) designed for 50-inch cutting decks on MTD, Troy-Bilt, Cub Cadet, and 359 Super GT lawn tractors. High-lift blades create stronger airflow under the deck for improved grass discharge and bagging performance, especially in thick or tall grass.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Your mower must have a 50-inch deck (measure cutting swath, not overall deck width).
• Model series: Fits MTD, Troy-Bilt, Cub Cadet, and 359 Super GT tractors using OEM blades 759-3813 or 742P3003. Common compatible models include Cub Cadet LTX 1050, Troy-Bilt Super Bronco 50, and MTD 13A-325-401.
• Measurements: Each blade is 20.5 inches long, 2.75 inches wide, with a 1-inch center hole and a 0.75-inch offset. Compare to your current blade’s length, hole size, and offset before ordering. Not compatible with 42-inch, 46-inch, or 54-inch decks.

Key Things to Know

• Quality: These are aftermarket blades, not OEM. Build and steel thickness are generally fine for residential use, but may wear faster than factory blades in heavy commercial mowing.
• Installation: Moderate difficulty. You’ll need a socket wrench, blade removal tool (or block of wood), and torque wrench (target 70-90 ft-lbs). Always disconnect the spark plug first.
• Gotchas: High-lift blades increase engine load and may cause vibration if not balanced after installation. Test spin the blades by hand before running—any wobble means re-check balance. Also, they can throw debris farther, so keep bystanders clear.
• Lift vs. mulching: These are high-lift, not mulching blades. If you want finer clippings left on the lawn, look for low-lift or mulching blades instead.

Should You Buy It

If you own a 50-inch MTD, Troy-Bilt, or Cub Cadet tractor and frequently bag grass or mow tall, thick lawns, this 3-pack offers solid value at $30. It’s a good budget-friendly upgrade from standard blades, but skip it if you need OEM precision, mulching performance, or a longer-lasting blade for commercial use.
