About as tight as I'd set a bike chain.  So, loose enough that there was 
noticeable play when reversing the drive sprocket by hand.

Ummm ... quite possible.  Now that I think about it, I swapped out the 
rear 
axle for a used one in the spring of 2021.  I may have just left the 
bearings on the used axle rather than bothering to swap them. Who knows 
what kind of shape they were in?  

I did grease them, though, and again this spring.

Yep, I'd think that the force of pulling me up the moderate slope in my 
pasture would be the main source of bearing stress.

It's almost certainly factory original.

Thanks for the reply!

If y'all think that "bike chain tight" is an OK choice, I'll tension it to 
that and button it up.  

It does make me a bit uneasy that getting to that tension requires that 
the 
pillow blocks be all the way forward, though.  Might back it off a bit.
