Ariens 24 inch cast iron gearbox and housing. Gearbox has been upgraded from the original aluminum gearbox to the newer style cast iron gearbox at some point, paint is in decent shape and not peeling off in sheets like most Ariens buckets, includes the chute. Should fit all 924 series Ariens that use a worm gear drive chute controller provided you have the right belt, calling or texting is best otherwise pm me here.
