The Bobcat 425 ZTS (zero-tail-swing) hydraulic excavator weighs in at 5,849 pounds in standard trim, or 6,257 pounds with the long-arm option. The excavator has a maximum digging depth of 8 feet 4 inches and a maximum reach at ground level of 14 feet 10 inches. A long-arm option increases those numbers to 9 feet 4 inches and 15 feet 9 inches, respectively, but does result in a slight (3-inch) tail swing, because of added counterweight. The new machine uses a 26-hp liquid- cooled diesel engine and provides an auxiliary hydraulic flow of 13.2 gpm.
