I met Karey at an expo show and he was showcasing the new Challenger Quickchange™ brush system. I think it’s important to know that the best competitors on the market usually require three or four hours to change a brush by removing the bearings and the core. With the Quickchange™ brush system, my staff was able to replace a brush in literally 90 seconds without a single tool. The time savings in itself is paying for the sweeper and is making me more money. Thanks Smith Equipment and Supply Company! I love your sweepers, you have a customer for life. I’ll see you in a few months or years for my replacement brushes.
