ThermoTraxx makes an aftermarket track-frame heating system for bulldozers, skid-steers, and other tracked heavy machinery, melting away ice and mud before frozen buildup damages the undercarriage. Conceived by excavating-industry veteran Dana Hennessy and engineered and built in the USA, the patented system is designed to reduce end-of-shift cleanup, repairs, and winter downtime. The company operates as ThermoTraxx under Prefer Traxx, LLC, with manufacturing support from Johnstown-based JWF Industries.
