HA HA, but really this is the best! I welded a concrete chisel to a pipe and use it to scrape the back and inside of the hopper. It works great. My hopper went from built up, to clean in one day.

I made a 4 ft air chisel bit to attach to my air chisel similar to that. worked good until another operator took it off my rig

I cut a chisel bit from our air chisel in half and welded the ends on a 5ft piece of #4rebar, it works awesome in the air chisel and reaches every nook and cranny of my hopper!

Use a tarp and u wont need any of that crap. Js

yeah good idea I heard a tarp INSIDE the hopper works pretty good

rookies.    LOL

will the hardened steel air tool chisel hold to mild rebar if welded properly?

i'm not that particular to tarp my pump off three times a day.. Plus i like to walk up on deck to pump sometimes or check the water box. Putz who are you calling a Rooky? If your too smart to try new ideas, you must have known it all in the sixth grade..Terry this Home depot 8 dollar chistle welded fine so far it hasn't fallen off:) What also works nice especially on my line pump is a six inch putty knife for scraping the back board and hopper. My boom is too hard to reach plus my grate is bolted down.

I used bar stock and welded a collar at the end using a washer that slid over the bar stock tight. then I notched and welded a flat piece at the end of the bar stock
