Know before you buy
These blades are designed as a direct replacement for specific MTD and Cub Cadet models that require an 18.5-inch blade with a 6-point star center hole. Always verify your mower's original part number against the Oregon 598-672 specifications to ensure compatibility before purchasing.
The tungsten carbide edge is significantly harder than standard steel, which allows the blade to maintain its sharpness for a much longer period. This reduces the frequency of sharpening and ensures a cleaner cut throughout the mowing season.
The aggressive blade angle increases airflow under the mower deck, which creates better lift. This improved suction helps stand grass blades upright for a more uniform cut and enhances the efficiency of both bagging and mulching clippings.
Yes, these blades are built with greater width and thickness compared to standard OEM options. This extra material increases the overall durability of the blade and helps it withstand debris and wear better over time.
While these are classified as mulching blades, their high-lift design makes them versatile enough to perform well with side discharge and bagging systems. The increased airflow helps move clippings out of the deck efficiently regardless of your discharge preference.
