Engine power of the new K-Series crawler dozers from Caterpillar – the D3K, D4K and D5K – has been increased 5 to 7 percent. All three hydrostatic-drive track type tractors are powered by the Tier-3-certified Cat C4.4 ACERT engine, rated at 74 horsepower for the D3K, 84 horsepower for the D4K, and 96 horses in the D5K. The new models feature a larger, quieter cab and seat-mounted electro-hydraulic controls with lever efforts decreased as much as 90 percent compared to conventional mechanical control levers. The machines can be shipped from the factory with SystemOne undercarriage, which Cat says extends track life.
