Caterpillar recently introduced the D6K track-type tractor, which is the first in a new line of crawler dozers designed to deliver best-in-class productivity and performance from first cut to finish grade. The D6K (Circle 900) comes standard with a new hydrostatic drivetrain, durable SystemOne undercarriage and seat-mounted electrohydraulic controls ready for easy installation of the AccuGrade grade-control system.
The Cat engine with ACERT technology delivers 125-hp flywheel power while meeting stringent worldwide emissions standards. Constant net horsepower ensures peak engine power is available for the drivetrain and implements even in high ambient temperatures. The D6K weighs 28,409 lb with the extended-length undercarriage and 29,690 lb with the low-ground-pressure undercarriage.
The D6K features a new hydrostatic drive system for excellent maneuverability, enhanced power-turn capability and variable speed control. The hydrostatic drivetrain provides independent power and control of each track for precise maneuvering, quick acceleration and fast on-the-go direction changes. The operator can command smooth power turns or even counter-rotation of the tracks by simply using the hydrostatic control located on the left armrest. Hydrostatic drive provides infinite speed selection from 0 to 6.2 mph in forward and reverse.
The D6K undercarriage features an oscillating track roller frame, which keeps more of the track on the ground in uneven terrain. The result is increased machine stability, decreased ground shock to the machine and a smoother, more comfortable ride.
