Grasscool 42" High-Lift Mulching Blade for 42-inch Decks — 6-Star 942-0616A, Mulch/Bag/Side-Discharge

Grasscool 942-0616A is a 42-inch high-lift mulching blade engineered as an exact OEM-style replacement to mulch, bag, or side-discharge grass clippings on Cub Cadet, Troy-Bilt, Craftsman and other 42" deck riding mowers.

If your mower deck needs a durable, precision-fit blade that restores cutting performance and airflow, the Grasscool 942-0616A is sized and shaped to match the factory 6-star mount pattern and lift profile. It’s made for homeowners who run 42" cutting decks and want a single blade that handles mulching, bagging, and side discharge without changing hardware. The blade’s dimensions, lift height and center hole geometry mirror common OEM part numbers so installation is straightforward and alignment is precise.

How does this blade change mulch, bag, and side-discharge performance?

The Grasscool 942-0616A is a three-in-one high-lift design that creates a strong, controlled airflow inside the deck. With the mulch plug installed the airflow circulates clippings for repeated cutting into finer pieces; with a bagger attached it funnels clippings up and into the collection bag; and with the chute open it directs clippings out across the lawn. Each mode relies on the blade’s curved profile and 1-1/2" lift to generate the appropriate vacuum and trajectory.

• High-lift profile increases suction for bagging and fine mulching.
• Curved cutting edge promotes repeated recutting for smaller clippings.
• Balanced airflow reduces clumping when deck and chute configurations are correct.

Which mower models and brands will this blade fit?

How does this blade handle tough mowing conditions?

The blade’s high-lift design and durable steel construction help manage weedy lawns, damp or dewy grass, overgrown turf and light debris. Strong airflow and repeated cutting action help reduce visible clumps and improve distribution whether mulching or discharging. As with any replacement blade, keep the blade sharp and replace if bent or excessively worn for safest, most effective results.

• Works well on tall, overgrown, or dew-covered grass when used correctly.
• Handles light twigs and leaf debris while improving clip distribution.
• Balanced shape reduces vibration and improves deck airflow consistency.

It’s aimed at users of Cub Cadet, Troy-Bilt, Craftsman, MTD and similar 42" deck tractors who need a reliable high-lift blade sized and punched to match factory spindles.
