Bobcat 428

Parts Compatible with the Bobcat 428 Mini Excavator

The 428 topped Bobcat's early 400-series excavator range before the E-series naming took over, and its listings reference letter-prefixed serial ranges such as A1HW11001 and above and A9K411001 and above. Excavator serials carry those alpha prefixes by build series, so match the full prefix, not just the numeric tail, when checking a listing.

As an excavator, the 428's fitment world differs from Bobcat's loaders: boom and X-Change attachment hardware, filtration, and cab parts are the categories that matter, and several of them carry over into the early E-series machines that replaced the 400s.

The window wiper blade replacing OEM 7188372 keeps the cab glass workable.
