Well, yes and no....
Meaning you have no external voltage regulator, but your engine has an alternator under the flywheel that,
when the engine is running, puts out a fixed voltage solely designed to keep the battery charged.
And you only need the battery to start the engine. So that's your regulation.
The alternator also has separate windings that put out a separate voltage strictly for your headlights.
The spark for your spark plug is magneto generated, so you don't need any battery voltage for that.

ok thank you for this explanation.
Alternators put our A/C so I should have been asking if my cub has a regulator/rectifier. I'm looking at the wiring diagram and I see the magneto output and two alternator outputs. Don't really understand where it is being rectified.

Yes it has a voltage regulator.
On your engine it's usually mounted right by the starter, on the engine block. Held on with 2 bolts and has a 3 wire plug.

Apologies, guyina4x4 is correct. I had model numbers confused.

Well you are forgiven for being confused given the mish mash of parts they threw on these things. In fact mine I believe has been re-powered. It has a Briggs Intek 17hp engine instead of the Kohlers they are listed as coming with.

I see the wiring changes color about 6" from the engine and the connectors have electrical tape on them so its almost definitely not original.

Will look for that regulator again today. Although I looked earlier where you described.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
