Move it! Getting trees horizontal is only the first of many moves, and John Deere Swing Machines are a one-stop shop for your forestry moving needs. With nine G-Series models available at your local Murphy Tractor & Equipment, you can create the fleet you need to tackle shovel logging, road construction, log loading, and processing tasks. Clever engineering, such as the “X” undercarriage design, delivers impressive load distribution at the ends of the track frames. Tracks are designed for strength and stability to negotiate muddy ruts, steep slopes, or whatever other muck and mire Mother Nature throws down. These tasks are accomplished powerfully and efficiently with a 9L diesel engine that delivers 30% more low-rpm horsepower and offers three productivity modes.
