The budrash GX22151 \/ GY20850 replacement blades are engineered for mulching — they create a vertical cutting angle that improves airflow through the deck and reduces clippings on the surface. Offered as a two-pack, each blade uses a 7-point star center mount and matches common John Deere part numbers so you can swap them in quickly.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these blades change cutting and mulching performance?\u003c\/h3\u003e\n\u003cp\u003eThese blades are designed with a raised mulching profile that lifts grass upward before slicing it finely. That vertical lift increases circulation under the deck, allowing clippings to be recirculated and cut multiple times for a finer finish. Expect more even dispersal and less visible clumping when installed correctly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMulching profile produces vertical suction and enhanced airflow\u003c\/li\u003e\n  \u003cli\u003eFiner clippings help decompose faster into turf without bagging\u003c\/li\u003e\n  \u003cli\u003eTwo blades per pack restore balanced cutting on 42\" decks\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these blades fit my John Deere model and spindle?\u003c\/h3\u003e\n\u003cp\u003eThese budrash blades are compatible with numerous John Deere models that use the GX22151 \/ GY20850 family of parts. They have a 7-point star center hole, so confirm your spindle uses the same 7-point star mount before ordering.
