DOZER GETS TECH
UPGRADE
John Deere integrated SmartGrade machine con-
trols on its 850K crawler dozer, which is said to
improve accuracy and quality of work through the
complete integration of the Topcon 3D-MC Grade
Control System. A key feature of the integrated
machine control is Auto SmartGrade, which allows
the operator to easily adjust the system when
moving the machine from one soil type to anoth-
er. It also automatically lifts the blade over heavy
loads before track slippage occurs when returning
the blade to grade.

AGGREGATE HANDLER
LOADS IN TWO PASSES
John Deere's 844K Series-III Aggregate Han-
dler features a 401-horsepower, 13.5-liter John
Deere PowerTech Tier 4 Final diesel engine. It
is equipped with standard five-speed transmis-
sion with torque-converter lockup in gears two
through five. This increases acceleration, speeds,
and cycles, and optimizes power and fuel effi-
ciency during transport, roading, and ramp climb-
ing. It is built for two-pass loading with increased
power, large tilt cylinders, higher hydraulic pres-
sure, and increased counterweighing to handle
bigger material-handling buckets. The result is a
30-percent decrease in loading time, eliminating
the third pass.
