Claim 0:
1. A pit launch horizontal drilling device comprising:
b) a chassis component comprising a back plate, a front plate configured to allow passage of a drill bore therethrough, and a centrally located chassis joining said back plate to said front plate, said chassis including a top surface and lateral opposing sides, each said chassis side comprising a toothed rack having a continuous substantially straight tooth profile extending along the chassis longitudinal axis and, coupled thereto,
c) a carriage component comprising
a pair of laterally opposed toothed gears dimensioned and positioned to engage said chassis toothed racks as pinions,
a hydraulic drive motor for rotating said toothed gears such that said carriage component can travel forward and back along said chassis toothed racks,
a hydraulic rotary drive for releasably coupling to a drill stem end to form a drill stem joint and rotating said coupled drill stem in opposing directions,
a straddle seat casing associated with said carriage component toothed gears such that said straddle seat casing can travel forward and back along said chassis toothed rack, said straddle seat dimensioned and configured to allow an operator to sit on said seat and operate said device, and
hydraulic controls engaged with said hydraulic rotary drive and said hydraulic drive motor for directing rotation of said coupled drill stem and traversal of said carriage component along said chassis toothed racks, said controls being manipulatable by said operator when seated on said straddle seat such that said seated operator can travel forward and back at will on said carriage component in said chassis component.
