3 Pack 942-05052A Mower Blades Replaces 742-05052A CMXGZAM110155 Medium Lift Mulching Blades for Cub Cadet XT1 LT50, XT2 LX50, XT1 GT50, RZT L50, RZT S50, Craftsman Z550, T260, 50" Deck Mower

What It Is

This is a 3-pack of medium-lift mulching blades designed for 50-inch deck Cub Cadet XT1, XT2, RZT, and GT series mowers, plus compatible Craftsman Z550 and T260 models. The medium-lift profile balances grass clipping lift for bagging with finer cutting for mulching.

Fitment & Compatibility

Check deck size first – only fits 50-inch decks. Measure your blade length (should be 20.5 inches center-to-center) and center hole (5/8-inch diameter). These replace OEM part numbers 942-05052A, 742-05052A, and CMXGZAM110155. Compatible models include Cub Cadet XT1 LT50, XT2 LX50, XT1 GT50, RZT L50, RZT S50, Craftsman Z550, and T260. Verify your mower’s deck model by looking for a sticker under the deck or on the frame; some 50-inch decks use different blade offsets or star patterns.

Key Things to Know

• Medium lift – not high-lift (better for bagging) or low-lift (better for dry grass). Ideal for mixed mulching and bagging.
• Installation – standard single-bolt center mount. Torque to 70-90 ft-lbs. Use a blade removal tool or block wood to prevent spinning.
• Sharpness – some users report needing to sharpen before first use for best performance. Inspect for burrs along the cutting edge.
• Balance check – always balance new blades after installation. An unbalanced blade causes vibration and wears spindle bearings.

Should You Buy It

If you own a Cub Cadet or Craftsman 50-inch deck mower listed above and want a cost-effective mulching blade set for regular lawn maintenance, this 3-pack delivers decent value. Skip it if you need high-lift blades for wet grass or prefer OEM-only parts – some aftermarket blades may require balancing or sharpening out of the box.
