I bought a used 3pt hitch fertilizer spreader for my tractor this year. The spreader is seized and the broadcasting mechanism will simply not turn. Beside the brute force approach, is there any chemical solution that is available to dissolve the corrosion caused by the leftover fertilizer that's in broadcasting mechanism?
I already tried PB Blaster and soaked it in some oil, but I think its going to take much more than that. I removed one of the roll pins that connects the broadcasting mechanism to the inside of the hopper wheel (see pic). I'm thinking about allying heat to the connection to try to break the hopper away so I can try to work on the broadcasting mechanism. As you can see it is quite corroded.
Any suggestions are appreciated.
