Troy-Bilt 46in High-Lift Replacement Blade Set for Mustang Decks — S-Shaped Center, Heat-Dipped Milled Edge

Troy-Bilt high-lift replacement blades (OE# 742P05510) are heat-dipped, milled from a single coil, and shaped to restore strong suction and clean cuts on 46" Troy-Bilt Mustang zero-turn and lawn tractor decks with an S-shaped center hole.

These are genuine Troy-Bilt replacement blades engineered to match the original equipment’s dimensions and performance. Heat-dipping increases durability and flexibility, while milling the cutting edge from one coil provides an even, consistent blade profile for smoother mowing. The S-shaped center hole fits specified 46" Troy-Bilt Mustang decks so installation is straightforward for owners who want OEM fit and function.

How do these blades improve cutting and bagging performance?

The high-lift geometry creates stronger airflow under the deck, lifting grass upright for a cleaner, more even cut and directing clippings toward the discharge or bagging system. That improved air movement helps collect seed heads and clippings when using a bagger and reduces the chance of clumps forming.

• Patented ultra high-lift profile increases suction for better grass lift
• Milled single-coil cutting edge for consistent sharpness across the span
• Designed to discharge or feed clippings into a collection system efficiently

Will these blades fit my 46" Troy-Bilt Mustang mower?

Yes — these blades are made to the original Troy-Bilt specifications for 46" Mustang zero-turn and lawn tractor decks that use an S-shaped center hole. Confirm your deck size and center mounting shape before ordering to ensure correct compatibility.

• OEM part number: 742P05510 (also referenced as 742-05510)
• Specifically for 46" decks with an S-shaped center mounting hole
• Sold as the original Troy-Bilt high-lift blade set for direct replacement

How are these blades made to last and maintain performance?

Manufacturing includes heat-dipping to add toughness and flexibility, reducing the chance of cracking or snapping under impact. The edge is milled from a single coil for uniform thickness and balance, which helps keep the cutter true and reduces vibration that wears components faster.

• Heat-treated (heat-dipped) for improved strength and fatigue resistance
• Milled edge from one coil for balanced cutting and longer edge life
• Precision dimensions match OEM tolerances to prevent wobble or imbalance

Should I use these blades for mulching or bagging?

These Troy-Bilt ultra high-lift blades are optimized for lift and discharge, making them excellent for bagging and efficient clipping evacuation. If you primarily mulch, Troy-Bilt recommends a compatible mulch kit and Xtreme mulch blades designed for finer clipping and recirculation inside the deck.

• Best for bagging and clean discharge of clippings and seed heads
• Pair with Troy-Bilt XTREME mulch kit (19A30047066) and XTREME blades for mulching
• Helps reduce clogging when mowing tall or damp grass

Who is this for: This blade set is intended for owners of 46" Troy-Bilt Mustang zero-turn mowers or compatible 46" Troy-Bilt decks that use an S-shaped center hole, who want OEM-fit replacement blades that restore suction, improve bagging performance, and maintain balanced cutting. Choose these if you prefer genuine Troy-Bilt parts for exact fit, reliable durability, and to keep your mower operating as designed.
