This 2004 Caterpillar D6R XL Series II is a heavy-duty, high-drive production dozer engineered for aggressive bulk earthmoving, deep ripping, and high-tractive utility work. With 13,590 original hours, this highly reliable, purely mechanical pre-DEF and pre-emissions asset is completely free of complex electronics, computer modules, or exhaust fluid overhead.

Featuring the extended XL track footprint for maximum fore-and-aft stability, this unit comes factory-equipped with an enclosed climate-controlled cab and a multi-shank rear hydraulic ripper. This is a clean, turn-key machine built during Cat’s peak era of structural durability, designed to go directly to the job site and generate immediate revenue.

• Factory Multi-Shank Ripper: Outfitted with a heavy-duty, parallelogram-style rear hydraulic ripper configured to tear through compacted soil, shale, and rocky terrain.
• Extended XL Track Layout: Extended roller frames provide a longer track-on-ground footprint, maximizing traction and ensuring smooth grading stability on uneven rights-of-way.
• Enclosed climate-controlled Cab: Fully sealed, structured cabin equipped with ergonomic pilot-operated controls.
• Elevated Sprocket Design: Legendary Cat high-drive chassis isolates the final drives and steering clutches from severe ground impact and structural shock loads.

Additional Information

• Ideal Core for Conversions: Because this machine is already equipped with a multi-shank ripper, it features the factory auxiliary hydraulic valve sections and structural mounting ears required to easily and cheaply plumb the tractor for heavy attachments like vibratory plows or winches.
• Lower Maintenance Overhead: Built before the introduction of complex computer networks and tier-emissions components, making it highly desirable for its straightforward serviceability and low operating cost per hour.
• High Resale and Demand: The D6R Series II remains an industry workhorse due to its bulletproof powertrain, making it a highly liquid asset that holds its value exceptionally well across the commercial market.
