Setting Up the Drill Head and Tracking
System
The drill head consists of two parts, the drill bit and the sonde
housing (Figure 37).

Drill bits vary in size and type to meet the various soil
conditions you may need to drill through. Some of the
possibilities are as follows:
•
Straight blade—Used in a wide range of medium density
soils.
•
Bent blade—Used in medium to soft soils. This bit has
an added 20° bend to increase steering performance in
soft soils.
•
Triangle point blade—Use in hard and rocky soils. This
bit has carbide edges to reduce wear.
All of the above bits come in varying widths. A wider blade
increases your ability to steer in soft soils. A narrower blade
moves through hard soils better. Contact your Authorized
Toro Dealer for a complete list of available blades.
The sondes and receivers are essential to track the position
of the drill head throughout the drilling operation. The
sonde housing on the drill head opens up to accept the sonde
beacon which works with the receiver to track the location,
pitch, direction, head orientation, and more of the drill head.
Refer to the Tracking System Operator's Manual for instructions
on using the system.
To install the sonde beacon into the sonde housing on the
drill head, complete the following:
1. Replace the batteries in the sonde beacon as described
in the Tracking System Operator's Manual.
2. Loosen the screws securing the housing cover to the
housing and remove the cover

Setting up the Machine for Drilling
1. Using the drive pendant, drive the machine to the
location that you have prepared for it, ensuring that
the front of the machine is the proper distance back
from entry point and the drill frame is in line with the
bore path.
2. Drive up to the location and make sure that all utilities
are located and marked prior to drilling.
3. Loosen the 4 screws that secure the covers over the
operator consoles and remove the covers
Note: Store them someplace safe for the day.
