You want to be careful on dropping and cleaning one from a land fill, {syringes}.
Oh yes, anything imaginable will be in the belly pans if landfill machines..
When I was subcontracting for a local landfill company I told the owner we need to drop all the pans and wash the machines every fall before freeze up.
He never would get it done..
Had a few times at -30 having to drop pans to access a blown hose or WHY, pans would be frozen on, heat with a tiger torch till the pan falls off, then proceed into the archeological chipping of frozen matter. I'd just charge the hell out of him to remind him why I wanted to clean the machines before it froze.
I don't miss working on that junk!!
