"Our Kelly Conveyor runs 24 hours, seven days a week. If you've been looking for a reliable, low-maintenance conveyor, look no more."

Paul Schmidt,
Schmidt's Ponderosa

"We purchased a Kelly bottom unload conveyor from Kelly Manufacturing several years ago. We struggled for years to find a conveyor that had a steep incline that could take the feed up in large quantities without spilling. This conveyor does just that. It's a minimal maintenance conveyor and we are able to use it for all feed stuffs from ground corn to silage. We also love the fact that if you have any questions and you call Kelly Manufacturing and actually talk to people who understand and build the conveyors."
