ACEBRI Mower Blades 42" for Cub Cadet Zero Turn Mower XT1 XT2, ZT1,RZT-L42, 942-04308, 942-0616A, 742-0616, 942-04126-X for Troy Bilt Pony Bronco 42 blades for Cub Cadet 42'' mulching blade, 2Pack

What It Is

This is a 2-pack of 42-inch mulching blades designed for select Cub Cadet and Troy Bilt zero-turn and lawn tractors. They replace OEM part numbers 942-04308, 942-0616A, 742-0616, and 942-04126-X, and are intended for cutting grass with a finer, mulch-style discharge.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch cutting deck—this is non-negotiable. The blades fit specific Cub Cadet XT1, XT2, ZT1, and RZT-L42 models, plus Troy Bilt Pony and Bronco 42-inch decks. Measure your existing blade’s center hole diameter (typically 5/8” or 7/8” on these models) and overall length (should be exactly 21 inches from tip to tip). Also verify the blade’s sail height and offset matches your OEM blade—mulching blades often have more lift than standard blades. If your mower uses a different hole pattern or airfoil shape, these won’t fit.

Key Things to Know

• OEM cross-reference: These are aftermarket replacements for OEM numbers 942-04308, 942-0616A, 742-0616, and 942-04126-X. If your mower uses a different OEM number, double-check length and hole size.
• Installation difficulty: Easy if you have a socket wrench and a block of wood to jam the blade. Torque the center bolt to 70-90 ft-lbs (check your manual). Left-hand threads are common on some models—verify direction before tightening.
• Mulching vs. side-discharge: These are mulching blades (curved with a higher lift). They won’t work well for bagging or side-discharge unless your deck has a mulching plug installed.
• Quality check: At $21.59 for a 2-pack, these are budget-friendly. Expect them to dull faster than OEM or premium aftermarket blades (e.g., Oregon G5). Inspect for burrs on the cutting edge before installing.

Should You Buy It

Buy these if you need a quick, low-cost replacement for a 42-inch Cub Cadet or Troy Bilt mower and primarily mulch grass clippings. They’re a decent value for light-to-medium use, but if you mow frequently or cut tough, tall grass, invest in a premium set for longer edge life and better cut quality.
