The Terex RS446D Reclaimer/Stabilizer features a powerful 415 hp (309 kW) diesel engine that meets stringent Tier 4i and Stage IIIB emissions standards. The new engine configuration improves fuel efficiency over previous RS446 models and reduces noise levels to the operator’s ear by 5 dBA for improved operator comfort. With the machine’s two-stage engine drive and three-speed cutter transmission that increases break-out force, the RS446D rivals the performance of 500-hp-class machines, while saving up to 30 percent on fuel costs.
Incorporated into the new design, a shorter engine cowling improves the operator’s line of sight to the front of the machine. The new hydraulically tilting hood offers easy access to engine components for quick servicing. The engine configuration in the RS446D positions all engine components, including the oil filter, air filter, fuel filter and battery, in a single service center accessed from ground level, reducing maintenance time for the service technician.
