Terre Products, 2 Pack High Lift Lawn Mower Blades, 42 Inch Deck, Compatible with Cub Cadet RZT42, XT1, XT2, 942-04308, 942-04308A, 942-04312, Troy Bilt Pony, Bronco, Mustang, 742-04308, 742-04312,

What It Is

This is a 2-pack of high-lift lawn mower blades designed for 42-inch cutting decks, intended to improve grass clipping suction and discharge in bagging or side-discharge applications. They fit select Cub Cadet and Troy-Bilt models, including the RZT42, XT1, XT2, Pony, Bronco, and Mustang.

Fitment & Compatibility

Before buying, confirm your deck is exactly 42 inches (measured blade tip to tip). These blades replace OEM part numbers 942-04308, 942-04308A, 942-04312, 742-04308, and 742-04312. They are aftermarket, not genuine Cub Cadet or Troy-Bilt. If your mower uses a different blade pattern (e.g., oval center hole, different offset), these will not fit. Measure your existing blade’s length, center hole shape, and thickness—these are typically 3/8-inch thick with a 5-point star center hole.

Key Things to Know

• High lift = better bagging, more power draw. Expect improved grass collection but slightly higher engine load and reduced fuel efficiency compared to medium-lift blades.
• Installation is straightforward if you have a socket set and a torque wrench (recommended torque: 70-90 ft-lbs). Use thread locker on the blade bolts.
• Check deck leveling after installation—uneven blades cause poor cut and vibration. Also inspect blade spindles for wear.
• Sharpening not recommended for high-lift blades; replace when dull (typically after 25 hours of use on heavy grass).

Should You Buy It

If you have a compatible 42-inch Cub Cadet or Troy-Bilt model and need better bagging performance, this is a solid, budget-friendly upgrade over standard blades. Avoid if you prefer OEM parts or have a different deck size/bolt pattern.
