CAT D9R

Description

The Caterpillar D9R is a production-class track-type tractor powered by the Cat 3408C diesel engine producing 405 flywheel horsepower (443 HP gross) from 18 liters of displacement. It carries a 107,550 lb operating weight with an SU blade and single-shank ripper, and moves earth with up to 163,000 lbf of drawbar pull in first gear.

A powershift transmission delivers 3 speeds forward and 3 reverse, reaching 7.4 mph forward and 9.1 mph reverse. Blade options run from the 9SU semi-universal at 17.7 yd³ to the 9U universal at 21.4 yd³, and the single-shank ripper reaches 48.5 in of penetration with 72,025 lbf of pryout force. The elevated sprocket design keeps final drives out of the debris path to extend undercarriage life.

Built for large earthmoving, mining support, and heavy construction, the D9R runs with no power derating up to 7,500 ft, which suits Four Corners jobsites at elevation. It rides on 24 in Extreme Service shoes with an 88.6 in track gauge for stability under heavy load. Inspections are welcome and financing is available through 4 Corners Equipment in Farmington, NM.
