What It Is

This is a set of three mulching blades and six-point star mounting nuts designed for 42-inch cutting decks on Troy-Bilt Bronco/Pony and Cub Cadet ZT1-42, XT1, and LT42 lawn tractors. The blades are aftermarket replacements for OEM part numbers 742-0616A and 942-0616A, optimized for fine mulching rather than side discharge or bagging.

Fitment & Compatibility

Before buying, confirm your deck is exactly 42 inches wide (measure blade tip to tip). These blades fit Troy-Bilt Bronco (model series 13A, 13W, 13B) and Pony (model series 13AN, 13BN) with 42-inch decks, plus Cub Cadet ZT1-42, XT1 LT42, and LT42. They replace OEM blades 742-0616A and 942-0616A. Do not assume all 42-inch Cub Cadet decks are the same – check your current blade’s center hole diameter (should be 1-inch hex) and overall length (should be 21 inches). The included six-point star nut is specific to these models; if your spindle uses a different nut (e.g., 5-point or standard hex), you’ll need to reuse your original hardware.

Key Things to Know

• Mulching only – these blades have a curved, high-lift design that recirculates clippings for fine cutting. They will not perform well for bagging or side discharge; use OEM-style blades for those modes.
• Installation difficulty – moderate. You’ll need a socket wrench, torque wrench (recommended 50-60 ft-lbs), and a blade removal tool or block of wood to prevent spinning. The star nut can be tricky to align; hand-tighten first.
• Quality check – these are aftermarket blades, not OEM. They are stamped steel, typically 0.1875 inches thick. Some users report they are slightly thinner than OEM, which may reduce lifespan in rocky or heavy grass conditions.
• Star nut included – the six-point nut is a plus, but verify your spindle accepts it. Some older Troy-Bilt models use a 5-point star nut; if so, reuse your original.

Should You Buy It

Buy these if you own a Troy-Bilt Bronco/Pony or Cub Cadet ZT1-42/XT1 LT42 with a 42-inch deck, want mulching performance, and are comfortable with basic blade replacement. The price is low, and the included star nut adds value, but lower blade thickness and aftermarket quality mean they’re best for light-to-moderate mowing on well-maintained lawns. Not ideal for heavy-duty use or rocky terrain.
