The IST Sno Pusher is the first steel trip edge designed for Sno Pushers to incorporate the longevity and limited moving parts of rubber-edge pushers. This urethane-based technology does not require springs or hinges. The design incorporates extended-wear shoes for a balanced, even push — along with a modified angle in the moldboard. According to the manufacturer, these two features, combined with the urethane tripping mechanism, provide a loaded torque on the steel edge that ensures effective ice scraping ability and a safe, consistent tripping mechanism.
