JD 400 buying option

Unfortunately my grandfather has just passed away. I have the option to buy his JD 400 from my grandmother, which I am sure i can get for a great price. My grandfather completely restored this tractor to perfect condition, and added a new motor. The tractor is setup with a plow and a hard top cab. I want the tractor to be setup with a snowblower. I am pretty handy, but I want to make sure I can get a snowblower for this model before I purchase it. I would like to setup the snowblower with electric switches to avoid having to turn a crank to switch the chute direction. Does anyone know what my options are?
