---------------------------------------

Enclosed fluid pump system is easy to winterize and helps keep pump warm during winter operation.

Integrated electronic system with guidance control enables the tracker operator to disable power to drilling unit's thrust and rotation.

Minimal drill maintenance; with no zerks to grease each day, you'll spend more time drilling and less time servicing the unit.

Tethered ground drive controller allows the operator to maneuver the drilling unit from a position that provides increased visibility, easier loading/unloading, and easier positioning.

Rack-and-pinion thrust system provides outstanding power transfer and performance for a wide range of directional drilling jobs.

Large-capacity pipe lubrication system minimizes maintenance time by keeping contamination out.

Efficient pipe loading system allows column selection from the operator's station; Mach 1 pipeloader automation is available to further simplify operation.

Two-speed carriage significantly decreases cycle time; assisted-makeup feature increases the life of drill pipe joints by automatically matching carriage movement speed with rotation during pipe makeup and breakout.
