MTD 719-0329 Flail Blade 3-Pack

What It Is

The MTD 719-0329 Flail Blade 3-Pack is a set of three replacement blades designed for flail-style mower decks, commonly used on lawn tractors and zero-turn mowers for mulching, leaf shredding, or rough turf maintenance.

Fitment & Compatibility

• Check deck type: These blades fit MTD, Troy-Bilt, Cub Cadet, and Yard-Man mowers with flail or “mulching” decks that accept a 1/4-inch thick blade with a 1-inch center hole and 4-inch overall length.
• Model verification: Confirm your mower’s model number (e.g., 13A-xxx, 17A-xxx) against MTD’s OEM parts lookup—these are factory replacements, not universal aftermarket.
• Measure existing blade: Compare length (4 inches), width (1.5 inches), and bolt hole size (1 inch). A mismatch in thickness (0.25 inch) or mounting hole pattern will cause poor fit or vibration.
• Deck size: Typically used on 42-inch to 54-inch decks, but not all—check your deck’s blade count and spacing.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and a torque wrench (set to 40-50 ft-lbs). No special tools needed, but ensure blades are oriented with the sharp edge facing the direction of rotation.
• Quality: OEM MTD steel, heat-treated for durability. Expect 2-3 seasons of moderate use before replacement, depending on debris and mowing frequency.
• Gotcha: Flail blades are not interchangeable with standard side-discharge or mulching blades—using the wrong type can damage the deck or reduce cutting performance.
• Set size: 3-pack covers most standard decks with 6 blades (2 sets needed) or 9 blades (3 sets). Count your existing blades before ordering.

Should You Buy It

If you own a compatible MTD-family mower with a flail deck and need a reliable, OEM-quality replacement, this 3-pack is a solid choice—especially for mulching leaves or maintaining rough areas. Skip it if your deck uses standard or high-lift blades, or if you’re on a tight budget (aftermarket options are cheaper but may lack fit precision).
