Features

Harvesting SATCO Processing Heads

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.

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.
