Description
Power Boss lists this as MBH66024PW056: the broom-main 56 inch 8 d.r. proex/wire. The same part is sold under other brand names as Minuteman MBH66024PW056, so a parts list naming any of those numbers points here.
Confirm the part number against your machine's model and serial number before ordering — these manufacturers share components across several machine lines, and fitment is model specific.
