Plan Bore Path
Plan the bore path, from entry to end, before drilling begins. The Ditch Witch Subsite Trac Management
System Plus is available for planning your bore path. This special software can be run in the field using a
laptop computer equipped with Windows
®
95 or higher operating system. See your Ditch Witch dealer for
details.
If not using Trac Management System Plus, mark the bore path on the ground with spray paint or flags, or
record it on paper for operator reference.
For complicated bores, consult an engineer. Have the jobsite surveyed and bore path calculated. Be sure
the engineer knows minimum entry pitch, bend limits of drill pipe, bend and tension limits of pullback
material, pipe lengths, and location of all underground utilities.
For less complicated bores, plan the bore based on four measurements:
• recommended bend limit
• entry pitch
• minimum setback
• minimum depth
IMPORTANT: See the following pages for more information about these measurements. If not using
Trac Management System Plus, see “Bore Path Calculator” on page 70 and use these measurements to
help plan your bore.
