Ditch Witch JT921

another to pullback and thrust, and a third to drilling fluid-which adds up to optimal hydraulic flow at all times. The JT921 does it all: powers itself and carries its own drill pipe and drilling fluid. The JT921 is a Fiber-to-the-Home contractor's dream. KEY FEATURES: -Outstanding horsepower (50 hp/77 kW) and hydraulic power provide the fastest cycle times of any units in their class, resulting in a greater number of FTTH, gas, water, or phone service installations per day. -Designed to make short- to medium-length service line installations with pilot bores up to 4 inches (102 mm) and backream diameters up to 12 inches (305 mm), depending on soil conditions. -A single lever operates both thrust and rotation functions, reducing operator fatigue. -Pipe lubrication system is controlled by a foot pedal at the operator's station, simplifying drill pipe maintenance. -Electronic system with tracker control enables the tracker operator to disable power to the drilling unit's thrust and rotation. -Fluid Miser drill pipe uses less drilling fluid overall, which means less jobsite mess and cleanup. -One-step anchoring system provides quick setup. -Choice of a wide variety of drilling bits, backreamers and service line pulling tools.
