The snap-ring design allows you to replace the bearing only, rather than swapping the entire pulley, saving time and money during routine service. It's engineered to fit a broad range of Bad Boy models and deck sizes from recent model years.\u003c\/p\u003e\n\n\u003ch3\u003eWill this pulley fit my Bad Boy model and deck size?\u003c\/h3\u003e\n\u003cp\u003eCompatibility covers many Bad Boy models and deck widths from 2017 through 2025.
