Caterpillar sells and supports the full line of SATCO harvesting attachments for cut-to-length and processing operations, robust attachments that fell and process trees at the stump or roadside. SATCO attachments are known for their durability and high performance.
In the northwestern U.S., a good choice would be the SAT323T, according to Glenn Brown, a Caterpillar product application specialist. The SAT323T, with a cutting capacity of 29 inches and topping saw capacity of 18 inches, features heavy-duty piston roller drives, larger roller arm cylinders, and the SATCO DEAD-LOCK pin retention system to provide maximum power and structural strength. SATCO’s robust ¾-inch base saw system delivers speed and dependability to tackle big wood.
The SAT323T features the SATCO TRI-KNIFE system, which improves measuring because it holds the tree in line with the measuring wheel better than two single knives. The TRI-KNIFE system “is more like a grapple,” said Brown, which makes it more adept at picking a log out of a pile and re-stacking cut logs.
Cat dealers provide support and stock genuine service and maintenance parts for the complete line of SATCO heads. All SATCO products are backed by Caterpillar warranties. www.cat.com
