What It Is

This is a 3-pack of mulching blades designed for 46-inch cutting decks on select Cub Cadet and Troy-Bilt lawn tractors. They replace OEM part numbers 942-0611A, 942-0612A, 742-0611A, and 942-04124, and are intended for mulching grass clippings into fine particles rather than side-discharging or bagging.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck and is one of these models: Cub Cadet LT1045, LT1046, i1046, or Troy-Bilt equivalents (check your owner’s manual or deck sticker). Measure the blade length—it should be 18.5 inches from tip to tip. The center hole is 1 inch diameter, and the blade thickness is 0.25 inch. These are aftermarket replacements for OEM numbers 942-0611A, 942-0612A, 742-0611A, and 942-04124. If your mower uses a different spindle pattern (e.g., 5-point star), these will not fit.

Key Things to Know

• Mulching vs. standard: These blades have a curved, serrated edge to chop clippings finer. They will not work well for bagging or side-discharge—use them only for mulching.
• Installation: Requires basic tools—socket wrench and torque wrench. Tighten blade bolts to 70–90 ft-lbs. Left-hand threads are common on Cub Cadet spindles; check before forcing.
• Quality: Made from heat-treated steel. Some users report they are slightly thinner than OEM blades, but still durable for residential use. Balance check recommended after installation.
• Gotcha: The black coating is cosmetic and will wear off quickly—does not affect performance. Do not sharpen these; replace when dull (typically after 25 hours of use).

Should You Buy It

If you own a Cub Cadet or Troy-Bilt with a 46-inch deck and primarily mulch your lawn, this kit is a solid, budget-friendly option. It’s not ideal for commercial use or for those who need bagging or side-discharge blades. For the price, it’s a reliable replacement for OEM parts, but double-check your deck size and blade length before ordering.
