Used buhler grain vac made by farm king for sale. Has three aluminum 10-12 ft 7-8 inch tubing. One 10-12 ft 5-6 inch black flexible tubing. One large suction spout and one small. Small one has a vaccum type attachment to help sweep floor when bin is low. Also has short 3-4 ft 7-8 inch tube. We bought it new a few years ago and ran 12-15000 bushel through it.
