STRAIGHTFORWARD CONTROLS.
Controls
with minimal electrical components,
bringing you
back to the basics with modern
technology.
NARROW FOOTPRINT. This drill is 8.5"
(21.6 cm) narrower in width
than the next sized
drill in the lineup and
can get through a 36"
(91.4 cm) gate or fit
on a narrow trailer with other
jobsite
essentials.
LOW SOUND LEVELS. Low noise emission
levels at the operator’s
ear of 85 dBa and a
guaranteed sound
power of 104 dBa make this
drill perfect
for installing small utilities in an urban
environment with minimal disruption.
MORE POWER. Equipped with a 48 hp
(35.8 kW) Kohler
engine, this drill offers
1200 ft-lb (1627 Nm)
of spindle torque and
7850 lb (3563.9 kg)
of thrust/pullback.
TRACKS. Tracks offer ideal traction for operation
while providing minimal ground disturbance.
This
track system design allows a forward
ground drive
speed of 2.8 mph (4.5 km/h),
which is 45% faster
than the leading
competitor.
MULTIPLE ROD OPTIONS. Equip your drill with
either a 6' (1.8 m), 1.66"
or 1.31" (4.2 cm or
3.3 cm) Firestick® drill
rod and save time on
the job with
180’ (54.9 m) of on-machine rod
carrying
capacity.
