here's a test.
Hook a 12v bulb or test light to the battery terminals,check the brightness,start the motor and see if the bulb gets brighter or burns out,if not something is up with your meter.

Found some interesting details.

The Starter/Generator can be tested the following way:
Resistance testing I have the following values
F Terminal to Case ~8 ohms
Gen Terminal to Case ~ 0.5 ohms
F Terminal to Gen Terminal ~ 8 ohms

From what I was able to find these are within allowable values. I then cleaned everything lubed and put it back together. Got it on the tractor and hooked up the gen terminal only and left the F terminal disconnected. Started the tractor and again the multimeter went to a high voltage. Looking at the amp gauge it showed discharge. I then hooked up the F terminal while it was running and it sparked a little and the rpm dropped. The amp gauge went positive.

So at this point I think the starting and the charging system is functioning properly. I think the multimeter is giving bad readings. I am going to get another multimeter and do some further testing. At this point if the voltage was indeed around 100 volts like the meter is saying I would think the light bulbs would blow but they are functioning just fine.

Dark, I agree I think the meter is a fluke and not in the brand name meaing lol. I think its giving bad readings for what ever reason. A friend gave it to me for free so who knows its story.

Thanks everyone for the help.

Your meter is TOAST...

If you were getting 100 VDC, it would burn your Ignition Coil up and then you would have nothing. The fact that the tractor starts indicates the voltage is in the "ball park:".

Totaly agree, kind of annoying that a meter would send me in a wild goose chase, but atleast I learned a little, and got the starter/generator cleaned out. The other meter I have is one of the cheepies from Harbor Freight. I think i need to invest in a better one with the electrical I am constantly doing around the house. Would be nice to have one that does inductive amperage. I guess thats nother topic altogether.

An alternator will run voltage up in the range you measured if it is unregulated and without diodes to produce DC current, but you do not have a modified alternator.
A generator by nature produces DC current and will not produce voltage in that range.
you would be lucky to see 18 DC volts.
A battery should if fully charged, read about 12.6 volts after 12-24 hours resting period.
Actually, a inexpensive throw away harbor freight type tester works pretty good in most applications.
You are not building a electronic circuit, just checking ball park readings.
I agree it sounds like you have a malfunctioning multimeter

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.
