Precision digging or laying pipe in just the right place shouldn’t be taxing. It should be
smooth and easy. Jerky controls, uneven bursts of power, or fatigue won’t be parts of your
workday due to Deere’s exclusive Powerwize II engine/hydraulic management system.
Powerwize technology lets the excavator arm be your “bionic” arm — an extension of your
own, only with a lot more muscle. It lets operators do precise work with a minimum of
effort — 10 percent less lever effort to be exact. There’s only one hydraulic mode, so just
select the desired engine mode, adjust the engine speed knob, and “go.”
The cooling system’s radiator is completely
welded from the tube to the header joint,
with a “square-wave” fin design to increase
heat transfer by 18 percent.
Deere PowerTech engines retain all the features
you’ve come to expect from Deere, and more.
Our wet-sleeve, individually replaceable cylinder
liners are admired throughout the industry for
their ability to eliminate hot spots.
Now this is cool: Deere’s cooling system
features a new airfoil fan that gives you
13 percent more cooling performance
while using 4 percent less horsepower.
The new fan also lowers noise level by
a significant 4 d(B)a.

Each Deere engine has an Electronic Control Unit (ECU) that
serves as an electronic “brain.” By regulating the fuel-injection
process, the ECU ensures smooth, safe effort without wasting
fuel. It also acts like a safety net by decreasing engine power
and speed automatically if key readings like fuel pressure or
temperature drift into the red zone.
We’ve increased hydraulic flow and
pressure to give you more
power and precision
at the end of the
boom. The new
design is very
“attachment
friendly.”
There’s more joy
in our sticks.
