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 sacrifi cing 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 effi cient 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 fl ow.
The new sucker fan design on the cooling
package pulls air in through the front
and out the sides.

The hydraulic reversible fan maximizes
debris management, and productivity,
by automatically blowing off the screen.
The hinged door optimizes serviceability
with easy access to the cooling package.
