The standard snowblower for the 400 is a Model 50. It plugs into the onboard hydraulic system front ports for raising/lowering and directing the chute. No switches needed-easy control levers to move-no cranking. The 50 is a single stage snowblower but works pretty darn well. There are snowblowers to be found.
Sorry about your grandfather. Hope you get his pristine 400 and keep his legacy going! Jay
