Well now that really muddies the water,
I did more tests.
I found another amp gauge that was a little more accurate and sensitive.
It showed that when putting the plate on the coil, that it did decrease amp draw but was more of a quick fluctuation and barely showed a difference in draw.
So I did a temp check,
after an hour, it got too hot for my dainty hand to touch @ *130 with plate to coil, using just a dial temp gauge I use for ac work not a calibrated one.

What surprised me was with driven plate removed mimicking a large, out of speck air gap, after another hour passed, no magic smoke and the temp at the same *130 as the previous test.
So have I busted another myth, or just created more questions?

Important thing is op has a working pto with no cost.

here I go again
If your engine is at full throttle you should show a charge, not a discharge on the gauge.
Now I'm going to a quiet corner and take up drinking, fall asleep and dream of something exciting.

The resistance of the coil windings is fixed and never changes, therefore the current going through it has to remain constant. current = voltage divided by resistance. (I=E/R).
So how does changing the air gap of a passive part in the game cause more current to flow thru the coil, whether it is a thousandth of an inch or a thousand miles. I'm probably wrong but I need it explained to me.

My money is on the windings shorting out, thereby lowering the coil resistance, thus sucking more current and heating the fuse and wire.

I agree with this completely. I was wondering the same thing.

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.
