Structures:
●
Leveraging a chassis design that has accumulated
more than 40,000 hours in demanding felling appli-
cations, the SATCO Directional Felling Heads have
a strong reputation of being one of the most reliable
and efficient directional felling heads on the market.
Hydraulics:
●
The directional felling heads are 100% hydraulic and
do not have any electronics on the head. SATCO’s
“HOSE THROUGH CENTER” connection to the
carrier allows the hoses to travel through the center
line of the attaching pins. This prevents the hoses
from over bending and causing premature failure. It
also protects the hoses from damage when falling
trees in dense forests. In addition, the 360 degree con-
tinuous rotation rotator allows felling in any possible
direction in relation to the carrier without being lim-
ited by a rotation stop and without the possibility to
damage hoses from over rotation of the head.
Saw Systems:
●
The saw units are supported by a large 30 cm (12 in)
diameter slew bearing making them a very robust
saw unit especially designed for falling large diameter
trees. The saw tensioning adjuster is a heavy duty
manual adjuster with ¾" pitch chain. The heads also
use a unique locking system for the saw sprocket to
prevent broken drive shaft keys and damaged saw
motor shafts.
Applications:
●
The SAT420 is ideally matched with a Cat 320D FM
harvester for efficient felling. The head is most effec-
tive when single felling trees between 305–508 mm
(12–20 in). The shorter tilt frame and chassis and the
smaller jaw opening provide quick motion to reset
the felling head for the next cut compared to a SAT630.
●
The SAT630 is ideally matched with a Cat 324D FM
Harvester or Cat 522B leveling track harvester. The
head provides the most benefit when single felling
trees between 457–762 mm (18–30 in). However the
SAT630 becomes more effective than the SAT420
when the majority of the trees being felled exceed
500 mm (20 in).
Owning & Operating Costs:
●
Both directional felling heads provide low owning
and operating costs when compared to traditional
high speed disc felling heads. Not only do the direc-
tional felling heads require less horsepower, consume
less fuel, the heads also provide less stress on carrier
components such as pins, bushings, stick, and boom
joints due to the floating motion of the head once
the trees are felled.
