You have to get the blower right inline with the pipe on the silo for blow to work otherwise you will end up with a pile of chafe under blower on the ground....take a little fussing to get it to line up don't worry about hight of blower as long as you get it lined up it should blow it into silo.....at fist when i tried it i was like that blower is way to tall to fit under filler pipe...but it will work it it just blends together the magic of pc lol no sledge hammer needed....hope this helps anybody messing around with it...you also got just a spec to line up for discharge but once you figure that all out its worth the time and hassle adds alot of reality to the game and be prepared its not a fast off load it takes some time to empty!!! Good Luck have Fun!!!
