Improved hydrostatic drive
From first cut to finish grade, Caterpillar’s D3K (74 hp/55kW), D4K (84 hp/63 kW) and D5K (96 hp/72kW) crawler dozers deliver productivity and performance. Power has been increased by five to seven percent for higher productivity.
These features and enhancements to the hydrostatic drive system give the K-Family a performance and cost advantage in general construction, site prep, forestry and other applications. The new models feature a larger, quieter cab and intuitive, seat-mounted controls to improve operator comfort and productivity. The machines can be shipped from the factory ready to accommodate the AccuGrade system, an exclusive Cat blade control solution that allows fast, precise grading. They can also be equipped with SystemOne undercarriage, a Cat innovation that offers long life and greatly reduced maintenance time and costs.
