It takes three days to clean down each combine, getting the dust and trash out of all the hidden parts on a harvester. Panels off, road compressor to blow the internals down and power washer for exterior panels. If you don’t get it right the mice and rats get into the combines in the winter and eat the electric wires and rubber, which can run into 10’s of thousands of new wiring looms so it’s an important job for the end of season but not the most glamorous.
