if the tractor runs well, charges and drives ok, you replaced the starter with a good know unit, it must be bad connection or battery

Sure seems it's restricted current flow somewhere.

A braided ground cable helped my nagging chasings of restrictions that occurred over multiple times.
The last time I had some broken wires in the cable to the starter where it had the insulation cover pinched by the p.o. by the clutch pedal.
It had got corroded out of sight. Didn't look bad. But robbed a little juice. And a 6 volt wants all the juice it can get.

Because your handcranking it easy enough it doesn't seem the flywheel is binding somewhere. (Had a mouse squished in a smaller engine before, Dried hard between a couple teeth. Fun figuring that resistance out...)

As suggested , revisit all terminals for clean , bright , and tight. And the contact surfaces clean and snug where the starter fits around it's bolts to tractor.

I had a friend that found a kids sock in his washing machine pump so a mouse on the flywheel would be a possibility to watch for. Although it sorta sounds like the title of a Disney movie.
Sure sounds like I have a battery issue.
So, when I "load test" the 6 volt battery, how should it read during cranking?
Thank you to all of you for your help!

Don, do your load test, first, directly on the posts of the battery, it should maintain 5 volts, or so while cranking. If the battery falls on it’s face, it’s a battery problem, charge it and try again. If it passes that test, move to the starter and repeat the test. If it fails, blame the cables or connections. Further testing will be needed to determine which cable or connection. If it passes, look at the starter switch or the starter, itself. If you still can’t figure it out, bring it to the Bash and I’ll give you a hand with it.

4.3 to 4.5 volts or higher while starter is cranking over the engine, battery good. Voltage will probably drop close to 4 volts when initially cranking the starter, then immediately rise to the desired voltage.

Full charge the battery before the test.
I have an excuse. CRS.

Update:
The battery did poorly on the load test - not much over 4 volts. Got a new Rural King battery and all seems good.
I struggle with keeping my batteries maintained for long periods of time and they are probably drained too often shortening their life. And I only have 2 Cubs! Geez.
Thank you all again for the help.

Don, Do you have battery maintainers for them?

I have 8 of these, and (knock on wood!!) my batteries have lasted for many years, so far...the oldest (12v) is probably 20 years old.
1 each on my 5 cubs, 1 on my golf cart, and 2 on cars.
I had to replace a couple under warranty that just quit working, but at the time I bought them, they were only about $20 each, so definitely worth it. I did just replace one NOT under warranty, and the price was about $40 from Tractor Supply (online).

With the price of batteries now days, it’s well worth the investment to pick up a couple maintainers, as mentioned above. I have several cheap, no name maintainers that I really like. They have several led’s that show the battery’s status at all times. When connected to battery that is not fully charged, they charge at a rate of 1.5 amps, a nice slow charge. They they maintain at 13.2 volts or about 6.8 for a 6volt battery.
I’m glad you’re back up and running, Don!
