942-04308 42 inch 6 Point Star Lawn Mower Blades for Troy Bilt Bronco Pony Mustang Cub Cadet XT1-42 ZT1-42 42" Zero Turn Lawn Tractor Craftsman T110 LT42 LTX1040 942-04308A 942-04312 High Lift/2 Pack

What It Is

These are 42-inch, 6-point star high-lift mower blades designed for residential lawn tractors and zero-turn mowers. They replace OEM part numbers 942-04308, 942-04308A, and 942-04312. The high-lift design increases airflow under the deck for better bagging and discharge, making them ideal for tall or damp grass.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 42 inches (not 46 or 50). These blades fit Troy-Bilt Bronco, Pony, Mustang, Cub Cadet XT1-42 and ZT1-42, Craftsman T110, LT42, and LTX1040 models with a 42" stamped deck. Also fits select Husqvarna, Poulan Pro, and MTD models using the same star pattern. Measure your existing blade length (center hole to tip) – it must be 21 inches. Check that your blade mounting hole is a 6-point star (not a 5-point or round hole) with a 1-inch center hole diameter. Verify the blade thickness (approx. 0.25 inches) matches your spindle. If your deck uses a different spindle or offset, these won’t work.

Key Things to Know

• High-lift trade-off: Better bagging and cutting, but more strain on the engine and deck. Not ideal for dry, dusty conditions or if you frequently hit thick weeds.
• Installation note: The 6-point star pattern is specific to MTD/Cub Cadet spindles. Use a torque wrench – tighten to 70-90 ft-lbs. Over-tightening can strip the star pattern.
• Quality check: Aftermarket blades – inspect for sharpness and balance before mounting. Some users report slight wobble if the center hole is not perfectly machined. Balance them if needed.
• Common gotcha: These blades are not compatible with 42" decks that use a single oval or round hole (e.g., older Craftsman or John Deere models). Always compare your old blade side-by-side.

Should You Buy It

Buy these if you have a 42" Troy-Bilt, Cub Cadet, or Craftsman tractor/zero-turn with a 6-point star spindle and need improved bagging performance in heavy grass. Skip them if your deck uses a different blade mount, you cut dry/light grass, or you prefer standard-lift blades for less engine load. At $25.98 for a 2-pack, they’re a solid value for the right machine.
