John Deere 444k Compact Loader User Manual


 
More power and
control mean more
productivity.
If you’ve got maximum productivity in mind, the K-Series Loaders
should be at the top of your list. But it’s not just their big torque
reserves that make them such impressive performers. Single-lever
joystick or two-lever Ɵngertip controls provide smooth, near-effort-
less control. Excavator-style hydraulics sense the load and deliver
the Ơow needed for smooth combined functions and fast work
cycles. You won’t Ɵnd a smoother-shifting loader, either. The
PowerShift™ torque-converter transmission (except the 644K Hybrid)
employs Smart-Shift™ technology to continuously evaluate speed
and load conditions, and adjusts clutch-pack engagement to suit.
Smart-Shift ensures that gear changes
are smooth as silk, regardless of
whether the bucket is empty or
fully loaded. 644K Hybrid utilizes
a hybrid-electric drivetrain. See
pages 10/11 for details.
Engine/hydraulic match maintains
good boom and bucket power into
and out of the pile. For big loads,
even in wet or packed materials.
Optional spin control boosts
productivity by improving traction
in troublesome material or underfoot
conditions. Reduces tire wear, fuel
costs, and operator fatigue, too.
Responsive steering and full 80-degree
articulation increase maneuverability
in tight quarters, for faster cycle times
and fewer three-point turns.
Hydraulic system provides only the
power required, so there’s no wasted
horsepower or fuel.
Boom-height kick-out and return-to-
carry functions help speed production
in repetitive loading applications.
On Powerllel-equipped loaders, the
touchpad has two presets for added
convenience when frequent attach-
ment changeover is required.
