Quieter, environmentally-friendly engine on dozer

Dressta NA has introduced the TD-40E EXTRA crawler dozer featuring a quieter, environmentally-friendly, Cummins QSK19 Tier 3 engine. This new model delivers an enhanced drawbar pull resulting from a higher maximum torque of 1,755 lb.-ft., up from the 1,650 lb.-ft. of the previous model. The new engine delivers 515 net horsepower at 2,000 rpm. Engine displacement continues at 1,150 cubic inches The TD-40E EXTRA has an operating weight of 136,509 pounds and a full-U blade capacity of 29.8 cubic yards. The cooling module has a two-speed fan with a 50-inch diameter blade to handle the cooling characteristics of the new Tier 3 engine. The low speed fan conserves power while providing a quieter operation when working with lighter loads or to deliver an extra boost of power for short periods under heavy load conditions. Also released with the TD-40E EXTRA are a gear range preselection system and an automatic downshift function which offers the operator the choice of various automatic operating modes, especially useful in repetitive cyclical operations. Contributing to a comfortable full day of work is the standard six-sided cab, which offers a deluxe interior with superior all-around visibility. The two doors and sliding side and rear windows provide excellent viewing from within the cab. To go along with the large view area out of the cab, excellent blade and ripper sight lines make it easier for the operator to have precise control of the machine. The cab is sealed and has a built-in air re-circulation system. It has a sound suppression system and is separated from the engine compartment for a quieter, more comfortable ride. The air-suspension operator's seat is adjustable and equipped with full arm rests and a three-inch retractable seat belt. The seat swivels 14 degrees to the right for better blade and ripper viewing and enhanced controllability designed to reduce operator fatigue. The joystick control provides up and down shifting of the transmission, Lo or Hi range selection of both left and right track drives, or full power geared turns. Pushing the right or left rocker switch selects the desired Hi or Lo range. Moving the joystick forward or backward moves the dozer in the same direction - a Front/Rear (F/R) detent provides hands-free motion. Moving the joystick left or right activates clutch-brake or pivot type turns.
