This is an interesting project. It looks worse than it really is, mostly just deep surface rust.
Some of the guards were missing. Photos from the internet were used as reference to making the new panels.
The rotten wood floor was removed and will be replaced with new wood. Everything else is sandblasted.
A light amount of filler was needed to finish the surfaces, then primer.
The wheels are painted and will get new tires mounted.
The spreader is painted and ready for re-assembly.
Finished Project.
