It sounds like there are a lot of things just a little bit wrong (It started hard but did start before the trip tells me that)

Getting an engine running and running right is just troubleshooting. one thing at a time until it runs.

4 requirements

Fuel
Compression
Timing
spark

The good news is each one can be checked separately. It ran not long ago so it has fuel (but as others have said, it could be dirty or have a dirty filter. The 5 min run points to a dirty filter) I would use fresh gas and a new filter before going any further.

Compression, It ran so it has it. might be low, That makes it hard to start but once you get it running you can check that.

Timing you can put the tractor in high or use the crank to turn it over and watch the points open, look at the timing mark and see what the timing is.

This will get you close, then once it is running you can tweek it.

Spark. Others have told you how to check for it. Problems are wiring and cleanliness. The dist cap, inside of the dis, and the coil and wires need to be clean and dry.

The low voltage side sounds suspect. I would disconnect all the wiring and hot wire it.
Battery to ground good heavy clean connection
Battery to starter same
Battery to coil (disconnect the tractor wiring to the coil and replace it with a temporary one of your own. now you know you have volts to the coil. no wiring, no switches, no charger, nothing else to worry about until it is running right.

(Remove this wire to stop engine)

There should be a wire (low voltage, not spark plug) from the coil to the distributor. Leave that wire, or if it is messed up, replace it also there should be a condenser connected to the points. is that there? is it clean?

As some one else said, you need a charger, A 10 amp will do. but you have to have one to trouble shoot and to bring the battery back up after the tractor has been sitting a long time.
