Cub Cadet 1170 Mower, Lawn and Garden Tractor

If you have an electric clutch, you will have to use the alternator and regulator off of your old engine or buy one that already has it on there. If you have a fuel pump mounted to your engine, you will also have to use it off of your old engine. If you buy the newer AVS style engine, the air breather is wider making the engine 2" wider. If you have a fuel pump and buy this style engine, you will have to buy one with a fuel pump or buy a new dip stick tube for the fuel pump to get its vacuum from.
