ENGINE & SYSTEMS
Wide fin spacing in the cooling system
allows trash to pass through the cores,
while a removable trash screen helps
eliminate plugging.
The top and bottom tanks of the heavy-
duty cooling system are heavy wall
extrusions that are TIG welded to the
core for maximum durability.
The John Deere PowerTech engine in the 120C
and 160C LC is charge-air cooled to improve
fuel economy and engine durability while
reducing emissions.
Remember the old adage, “If you can’t take the heat, get out of the kitchen”? Well, these
excavators will stay in the kitchen longer than a chef at a four-star restaurant. That’s due
largely to the heavy-duty cooling system.
It features an aluminum bar-plate design with high-temp liquid-braze process for
superior strength. There’s also the hybrid steel-and-plastic fan with an airfoil-blade design
that results in more cooling performance while using less horsepower. Plus the fan runs
much quieter, which may help you think about your next big project.
The John Deere 4.5-liter PowerTech turbocharged and charge-air-cooled engine provides
steady power and meets the EPA and CARB emission non-road regulations. It’s just one more
confidence-building feature that will help you cook up more business and higher profits.
