Oversize Flighting Boosts Auger Capacity
"It gives my 8-in. dia. auger about one third more capacity," says David Morgan, Col-fax, Wash., who removed the bottom 1 ft. of his 60-ft. long bin filling auger and replaced it with 10-in. dia auger flighting that's tapered down to 8 in. dia. where the two augers meet.
Morgan welded a stub shaft between the two auger shafts, then Used a cutting torch to cut the 10-in. dia flighting down gradually to 8-in. He also attached a large 36-in. wide, 20-in. high hopper to the end of the auger to virtually eliminate grain spillage.
"The limiting factor on inclined augers is that they can't load themselves fast enough. Using oversize flighting force feeds grain into the auger," says Morgan. "I got the idea when we bought another combine and needed to unload our trucks faster. Some commercial augers have an extra length of flighting on the end to increase capacity, but I think a single length of oversize flighting works better. The same idea could be used on any size auger."
Morgan's add-on hopper has a metal base with sides made out of rubber elevator belting which prevents damage by trucks. "The oversize hopper saves time when moving the auger from one bin to another because there's nothing to clean up," notes Morgan.
He mounted a sealed bearing in the hopper's end plate to support the auger. "Most commercial augers have a bronze bushing that gets buried in dirt and grit, and if the bushing isn't greased it wears out quickly. My sealed bearing should last several years."
