Built to Work Hard
The Model 579 is built to last. We made the new aluminum cab solid and durable, with the highest quality fit and finish. An in-mold process embeds color directly onto the dash for a long-lasting finish that virtually eliminates fading, scratching and peeling. Electrical wiring carriages support wiring and reduce wear and tear, adding to the overall durability of the components.
