Hi,\n\nI have a good working fuel motor of a mower and would like to build a vacuum sucker with it for horse manure. I can assemble everything from scratch what i like to do but I just don't understand the principle of how to assemble things to work properly. Ok I need to suck the air with a propellor so that the manure ends up in a bin. My question : when I suck air with a propellor, how can i prevent the manure from getting into the propellor and get it in the bin ... ??
