FWIW:
High amperage draw, or over current is what will cause a fuse to "blow" High voltage has nothing to do with high current draw. Amperage and voltage are apples to oranges comparison. you have too high a current draw for the rating of the fuse. find the short to ground or component that is drawing to much current/amperage.

There is a guy on ebay that maybe can rebuild your old PTO. Yours probably has a 1 1/4" crankshaft so it will be hard to find a replacement.

Thanks for the information on the PTO...very pricey. That's more than 1/2 what I paid for tractor, wheel weights, chains, 60 inch Haban Deck and Power Angle snow blade 4 years ago!
I did check for continuity with the battery unplugged as suggested by Oak. When I turned on the lights, my meter beeped. When I turned it to on, it also beeped constantly, regardless of which of the wires I moved around. As an aside, my started had sounded like it was grinding a bit over the past several months. My son and I had previously taken all of the heat shrouds off to find that the nuts had come off entirely and the starter was just sitting on the studs. We tightened it up as best as I was able, and put a jam nut on to try and keep it tight, but admittedly, the tools I have didn't do a great job of getting into the small space to really crank it tight. I say this, because when I tried to start it today, it really sound like it was grinding a TON and bogging down, and I saw sparks coming out from under the heat shroud. When I reached underneath to the starter, I could wiggle it by hand. Looks like I will need to get in there again. Could it possibly be something with the starter causing it to short? I appreciate your help. I am getting frustrated as electrical isn't my specialty. I am reaching the point I might just take it to someone, but I have a son in college and my free money is going there. My wife wouldn't be too pleased with me paying someone hundreds of dollars to fix this old tractor.

Some say you can service the starter with the in the tractor. I found it is much easier to lift the engine to service it. It takes a less time to pull the engine than you think.

I could be wrong, but I doubt your starter is causing the fuse to blow. When you are out there putting th 2072 to work, the fuse blows during run cycle. That's when your PTO goes out because it loses power after fuse blows. Tractor can still run because it has magneto and does not need power. The starter is inactive since the machine is running and you are not in start cycle.
In summary, IMO,.... the loose starter is a separate and different issue and is probably not connected to blowing the fuse. The starter, by itself, is not directly connected thru the fuse but the solenoid which activates the starter is connected thru this fuse When you get your starter fixed.... since you stated you aren't electrically inclined, I wonder if the fuse blow if you NOT use the PTO and/or the lights? If fuse still blows without the use of PTO and lights, you could could eliminate those two possible culprits if not completely.

To track down a short, wire a head light bulb in place of the fuse. When the short is located, the bulb will light. Fix the short with no blown fuses.

Thank you to everyone who posted with helpful hints and technical support. After going through the wiring for just about the entire tractor, I lifted the seat only to find a 1-in section of insulation rubbed off of the positive battery cable. Fixed that, pulled the motor and tightened up the starter, and now everything works as it should. Again thanks everyone for all of your help, I really do appreciate it

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.
