Powered by a 63-horsepower Kubota diesel engine, Vermeer™s D16x20 Series II Navigator horizontal directional drill provides 16,000 pounds of thrust pullback force and 2,000 foot-pounds of torque. For added control in varying soil conditions, the standard AutoDrill function allows the operator to set rotation, thrust and pullback pressure. The drill then adjusts bore and pullback speeds as it works through the bore. Sliding tracks adjust outward for improved stability in uneven terrain. When returned to inward position, the drill has a compact footprint.
