Features:
Structures:
●
SATCO processing heads are designed with high
tensile strength materials and utilize large pins for
durability. The roller arm and knife pins on the heads
are retained using SATCO’s “DEAD-LOCK” pin
retention system utilizing the pin for added strength
in the chassis. The “DEAD-LOCK” pin retention
system also prevents the pin from moving in all three
axis improving bushing life and extending service
intervals.
Hydraulics:
●
A Rex Roth main valve is used on all SATCO pro-
cessing heads and is rated at 420 bar (6100 psi) eliminat-
ing the need for carrier pressure reduction. SATCO’s
“HOSE THROUGH CENTER” connection to the
carrier allows the hoses to travel through the center
line of the attaching pins preventing the hoses from
over bending and causing premature failure. It also
protects the hoses from damage when falling trees in
dense forests.
Saw Systems:
●
SATCO processing heads utilize two different main
saw systems depending on the head model. Most
heads come equipped with SATCO’s designed ¾"
manual tension main saw system. The main saw
units are supported by a large 30 cm (12 in) diameter
slew bearing making them a very robust saw unit.
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 pre-
vent broken drive shaft keys and damaged saw motor
shafts.
●
The SAT214, SAT318T SC, SAT322T SC, and
SAT323T SC all utilize the Huldtins SuperCut 100.
The SC100 features 0.404" automatic chain tension-
ing and an integrated lubrication system.
●
The SuperCut 100 is also used on most of the heads
denoted by a “T” as a topping saw. This feature pro-
vides added versatility to the operator when processing.
The one exception is the SAT325T which is equipped
with the same SATCO designed ¾" saw system for
both the main and topping saws.
Applications:
●
The SAT214 is designed for pine thinning and select
cutting smaller mixed stands. This head performs
well in pine plantations and mixed natural stands.
●
The SAT318/SAT318T/SAT318T SC are equipped with
TMVW drive motors designed for lighter weight tim-
ber and perfect for feeding down to small diameters.
●
The SAT322/SAT322T/SAT322T SC are equipped
with HD hubs on the drive motors and work per-
fectly for larger heavy timber while still maintaining
the ability to install on a 320D FM or a 521B/522B
track harvester.
●
The SAT323/SAT323T/SAT323T SC are equipped
with MS11 drive motors providing increased torque.
These heads paired with the 324D FM/325D FM
machines have the capacity to consistently process
large timber.
●
The “SC” versions of the 18, 22, 23 inch heads works
well for softwood applications and provides faster
cutting cycles.
●
Debarking is the specialty of the SAT422 DB and can
handle a wide range of eucalyptus and acacia trees.
●
The SAT223/SAT223T are best suited for processing
short wood (6 m [20 ft]) or less. It is equipped with
four knives and provides optimal delimbing of large
limby wood.
●
The largest offering is the SAT325/SAT325T and is
designed for our largest FM the 568 FM. These
heads work with the largest timber our machines can
handle and stand up to the toughest applications.
