Already put plenty of lubricating oil (machine oil) which is supposed
to have water displacing (WD) properties, but it's just not working
itself down the shaft. I guess you're right, back to the curb it goes.

End of last fall season I acquired a used Scotts broadcast spreader
(at the curb on trash day). The rotating mechanism is corroded and
hard to turn. Yesterday I decided it's time to work on it and see if I
can get it to working condition again. I lubed all rotating joints and
the gear. It's at the point where I think the problem is at the hopper
where the driveshaft and the plastic meet and penetrating oil can't
(or hasn't) get in there. I gave it a brief try but didn't want to
force anything. Looks like there is a rolled pin and a collar with a
set screw. I lightly punched the pin and tried to unscrew the set
screw but neither budged. Anyone even taken this thing apart?

Give it a spray of WD-40. If that doesn't work it's not worth fixing
and it's time to take it back to the curb! Spreaders need to be
washed and rinsed after each use else the metal parts will quickly
corrode.
