Dressta NA has introduced the TD-25M Extra and TD-25M LA (Landfill Application) Extra series crawler dozers. These dozers feature a more powerful Tier III Cummins engine to meet lower emission requirements. Net power has increased to 330 hp (246 kW), up from 320 hp (238 kW) for the previous models. Maximum torque also has increased 11 percent to 1,346 ft-lbs. Maximum power is now attained at 1,800 rpm, 300 rpm lower than previously, reducing overall noise levels.
To absorb the higher power and torque at lower engine speeds, Dressta has revised the torque converter, hydraulic pump drives, and final drives.
Also released with the TD-25M Extra series is 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. A continuously variable speed, hydraulically driven fan, designed to match the varying heat loads on the dozer is included. On the landfill version, the fan also is hydraulically reversible.
The TD-25M Extra has an operating weight of 79,873 lbs. (36,230 kg) and blade capacity, in soil, up to 15 cu. yd. (11.5 cu m), while the landfill version weighs approximately 86,000 lbs. (39,009 kg) with blade capacities to 27.9 cu. yds. (21.33 cu m).
