Caterpillar has refined the design of its skid steer and compact track load- ers and designated the line B-Series 3. Models include 216B3, 226B3, 236B3, 242B3 and 252B3 skid steers and 247B3 and 257B3 compact track loaders. A redesigned dead-engine lower valve provides an easier-to-use, more-positive means of lowering the lift arms if the machine should run out of fuel or stall with the arms raised. A new lever-action handle acts di- rectly on the hydraulic relief valve. A new single ECM has been moved from the lower frame to the back of the cab and provides easier access to electrical service points as well as simplified wiring and a reduction in the number of connections. Cat added power to the 242B3 skid steer and 257B3 compact track loader with a 71-horsepower engine, which in- creases net power by 25 percent, and a hydraulic system with about 40 percent more standard flow, at 22 gpm.
The Cat 307E2 mini excavator expands the mini hydraulic excavator machine range to include an additional solution for the 7- to 8-metric-ton weight class. The 50.3-horsepower Cat C2.4 turbo engine is Tier 4-Final.
The Caterpillar 325F is a compact radius excavator built with a Tier 4-Final Cat C4.4 ACERT engine paired with a responsive hydraulic system.
