Standard decking blade has a replaceable, weld-on cutting edge of high-carbon material for longer life.

A heavy-duty blade (optional on the 648G-III, standard on the 748G-III) is wider at 9-ft 8-in (2,95 m) with a heavier weldon cutting edge for more tire protection and improved weight distribution.

A high torque motor drives the grapple through 360-degree continuous rotation.

John Deere winches provide the power and confidence you need to skid big loads.

CABLE SKIDDERS

MAKE THE MOST OF EVERY LOAD.

G-III Series Cable Skidders have the power to skid big loads.

John Deere winches give you the power and reliability you need. They are easy to operate with a single lever, and feature powerful line pull, sealed wet-disc clutches, and spring-applied, hydraulically activated brakes for extreme durability.

The rear assembly is built forest-tough to withstand the heavy buffering they endure. The adjustable fairlead, heavy butt pan, see-through ramguard screen, and strong fenders protect the tires, rear frame, winch, and more importantly—the operator.

The fenders are shaped

to guide butts into the best position for load control during skidding.

LET’S KICK THE TIRES.

The standard 4000 winch on cable skidders boosts a bare drum line pull up to 47,697 lbf (212 kN), while the optional 6000, only available on the 640G-III, pulls a massive 50,517 lbf (225 kN). They are both easily operated with a single lever and feature sealed, wet-disc clutches and springapplied, hydraulically activated brakes for extreme durability.

6.8 L and 8.1 L Deere engines feature high torque rise, heavyduty engine blocks, proven durability and fuel efficiency.

Industry-leading Deere diesel engines feature Powershift transmissions, with seven forward and six reverse gears, which are controlled with a bump shifter for ease of operation.

Industry-leading cab design utilizes isolation mounts for reduced noise, vibration, and driver fatigue. Operator comforts include a seat that swivels up to 30 degrees, ergonomically located controls, a tilt/telescopic steering wheel, and climate control for all-season comfort.

Grapples are designed with

two hydraulic cylinders that adjust to each load. Closed-center, load-sensing hydraulics maintain constant pressure on the tongs. Three internal ribs on each tong make them stronger without adding weight, and tong tips are constructed of wear-resistant cast steel for a reliable grip.

Inboard planetary axles feature wet disc brakes sealed and immersed in cooling oil bath. They are self-equalizing and self-adjusting to decrease wear with on-the-fly diff locks.

THE 600 SERIES SKIDDERS

RUN CLEAN WITHOUT COMPROMISE.

The muscle behind the 600 Series Skidders is the powerful PowerTech Plus™ 6.8 L engine that runs clean without sacrificing power.

All John Deere skidder engines meet EPA and CARB emission non-road regulations, while maintaining the legendary John Deere power.

Exhaust gas recirculation (EGR) cools and mixes measured amounts of exhaust gas with incoming fresh air to lower peak combustion temperatures and reduce emissions.

And the engine’s four-valve design, with high-pressure common rail fuel injection, provides greater low-speed torque and better transient response.

The 600 Series Skidders feature an enhanced cooling system with a new, more efficient sucker fan design, which draws air in the front, through the cooling package and out the sides. The hydraulically driven cooling fan is temperature controlled, so it runs only as needed, minimizing horsepower use and drag. The fan is fully reversible to automatically blow debris off the grill screen, optimizing air flow.

The hydraulic reversible fan maximizes debris management, and productivity, by automatically blowing off the screen.

The new sucker fan design on the cooling package pulls air in through the front and out the sides.

The hinged door optimizes serviceability with easy access to the cooling package.
