NEW DRESSTA TD-40E EXTRA CRAWLER DOZER
Dressta has introduced the largest model in it’s line the TD-40E EXTRA crawler dozer featuring an, environmentally friendly quieter Cummins QSK19 Tier 3 engine.
This new model delivers excellent drawbar pull resulting from a high maximum torque. The new engine delivers 515 net horsepower at 2000 rpm. The massive cooling module is equipped with a hydraulically driven two-speed fan to handle
the cooling characteristics of the new Tier 3 engine.
A number of features released with the TD-40E EXTRA are a gear range preselection system that includes an automatic downshift function that offers the operator a choice of various automatic operating modes, especially useful in repetitive cyclical operations.
Contributing to a productive full day of work is the standard six-sided cab, which offers a comfortable interior with superior all around visibility.
The two doors and sliding side and rear windows provide excellent viewing from within the cab. Along with the large viewing area from the cab, excellent blade and ripper sight lines enable the operator to have precise control of the machine with ergonomically designed controls. The cab is sealed and has a built-in air re-circulation system. Sound suppressed and 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 retractable seat belt. The seat swivels 14 degrees to the right for greater view of the ripper and enhanced controllability designed to reduce operator fatigue.
The combination of a three-speed transmission with Dressta’s exclusive two-speed (Hi/Lo) steering provides six forward and six reverse speeds for unsurpassed load-matching capabilities. Dressta engineers have combined the hydraulic control system on the TD-40E EXTRA with advanced solid - state electronic circuitry in an exclusive electro-hydraulic motion control system. All control functions are activated by movement of the joystick or by selecting control buttons on the face of the joystick. The joystick control provides both 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 back moves the dozer in the desired direction - a Front / Rear detent provides hands-free motion, moving the joystick to the left or right activates clutch-brake or pivot type turns.
A rear platform located below the fuel tank aids in refuelling, air conditioning filter changes and cab rear window cleaning to enhance serviceability. Maintenance on the Dressta TD-40E EXTRA includes a 500-hour oil change interval. The air conditioner condenser has been moved to the rear of the cab roof for easier access.
