Two hydrostatic compact crawler dozers—the 22,000-pound TD-8S and 24,250-pound TD-9S—are available to the North American market. The new dozers use a dual-path hydrostatic drive system that enables full power to both tracks during gradual turns and counter-rotation pivot turns. The new tractors are powered by electronically controlled, Tier 4-Final, QSF 3.8 Cummins engines that use a selective catalytic reduction system and are rated, respectively, at 100 and 120 horsepower (gross). A six-way blade (rated at 2.4 and 2.9 cubic yards, respectively, with the long-track undercarriage) mounts via a C-frame. A low-ground-pressure configuration is available. Both undercarriages use lubricated track chains and a split-link. A multi-shank ripper is available. A new cab features a 7-inch LCD screen and joystick control of steering and implements. S-Series dozers are available, says Dressta, with integrated technology options of Trimble Ready and full Trimble 3D control systems.
