DEERE 644 P-TIERMID-SIZE WHEEL LOADERS
ABOVE AND BEYOND INTRODUCING THE P-TIER WHEEL LOADERS
When your material-handling application needs a heavy-duty lift, add a P-Tier Wheel Loader to your lineup. Combining convenient front-end features with near-parallel lift, spacious operator stations including customizable ergonomic electrohydraulic (EH) controls, and streamlined electrical and hydraulic routing, these versatile and productive mid-size models are designed to help you take your operation to the next level.
Operators can easily control up to six functions without letting go of the ergonomically designed joystick. Two industry-exclusive multifunction buttons can each be programmed to handle any of up to 10 functions selected through the monitor, including bucket vibrate and EH Precision mode.
THE BUCKET LIST
A wide selection of enhanced production buckets with integrated spill guards, curved side cutters, and impressive rollback delivers elevated bucket-fill performance and material retention compared to earlier offerings.
REMOTE DIAGNOSTICS AND SUPPORT
To maximize uptime and lower costs, JDLink telematics provides machine location, utilization data, and alerts to help you maximize productivity and efficiency. JDLink also enables John Deere Connected Support. Dealers use Expert Alerts based on data from thousands of connected machines to proactively address conditions that may otherwise likely lead to downtime. Your dealer can also monitor machine health and leverage remote diagnostics and programming capability to further diagnose problems and even update machine software without a time-consuming trip to the jobsite.*
AT THE FOREFRONT
Featuring bucket and linkage designs that improve load leveling, material retention, and visibility, these loaders yield more productivity and performance than previous models.
ITS EASY TO SEE
Large seven-inch in-cab display with easy-on-the-eyes clarity enables intuitive push-button access to key info. Standard rearview camera displays the activity behind the machine on the color LCD screen.
ON YOUR SIDE
All daily service points including fuel refill are conveniently grouped at ground level on the left side of the machine for easy access. Routing of electrical wire harnesses and hydraulic hoses has been streamlined.
GET AHEAD MOVING FORWARD
Designed to elevate your productivity, the 644 P-Tier Wheel Loader helps you put your best foot forward.
HAVE A SEAT
Spacious and comfortable cab features extra legroom, an improved HVAC system, additional storage, and a more adjustable seat than earlier models.
Seat-mounted right-hand joystick features two programmable multifunction buttons and electrohydraulic (EH) controls that are more intuitive to operate compared to our K-Series controls.
Lift path on Z-Bar linkage is near parallel. Better load-leveling capability compared to K-Series models minimizes load rollback, reduces material spillage, and requires fewer manual adjustments. Cross-tube and boom geometry of the Z-Bar linkage has been streamlined to provide a better view to the front attachment.
STICK A FORK ON IT
Available in 60- and 72-inch lengths, improved shaft-style forks enable better visibility to the fork tips compared to previous models.
Improved visibility to the work tool helps reduce spillage as well as cycle and tool-changeover times. It also helps minimize machine damage when working on crowded jobsites or up against walls.
STEP IT UP
Quad-Cool places the radiator, air-conditioner condenser, intercooler, and hydraulic, transmission, and optional axle coolers in a unique boxed configuration thats isolated from engine heat, boosting efficiency and durability.
REACH HIGHER AND MOVE MORE MATERIAL WITH Z-BAR LINKAGE AND BUCKET IMPROVEMENT
The Z-Bar linkage has been completely redesigned to improve visibility and provide a high degree of parallelism while the upgrades made to the enhanced performance bucket offerings help increase productivity.
Cross tube and boom geometry changes mean improved visibility to front attachments when operating and changing out
Standard 8 degrees of parallelism minimizes load rollback when using forks to improve load leveling
High-Lift linkage adds an additional 12 of hinge pin height over standard linkage
Bucket material retention has been improved by providing a 15 degree increase in bucket rollback to reduce material spillage
Curved side cutters and integrated spill guards improve bucket fill rates
ALL DAY COMFORT IN THE REDESIGNED CAB
The redesigned cab in the John Deere utility loader lineup features improvements that provide the operator a first-class work environment with a range of creature comfort options to keep operators comfortable and productive no matter the task at hand.
An additional 3 in. of leg room has been added over the previous series loaders.
Dual tilt steering column allows for dual tilt between the column and wheel to allow operators to customize the position of the steering wheel to their needs.
Additional 12V accessory outlets have been strategically placed for proper powering of devices and a USB port has been added for connecting to the radio.
Auxiliary accessory mounting points are strategically placed on the right front and rear cab posts for equipment such as a payload scale interface or CB radio.
Upgraded HVAC system to improve cooling capacity, more precise control and increased reliability and durability.
The sealed switch module has been updated and relocated on L-series and P-tier loaders. The new location brings the switches to the operators line of sight during operation for quick reference and ease of selection and has updated and new functions included.
INCREASE THE LOADERS FUNCTIONALITY WITH ELECTROHYDRAULIC (EH) CONTROLS
Electrohydraulic (EH) controls allow for increased functionality to customize machine operations based on operator preference to increase productivity on a range of jobsite applications
Enable soft hydraulic stops to select how abrupt the bucket or boom stops when they reach the end of travel or when the lever of the joystick is released
Personalize both multi-function buttons with up to 10 options selectable from the monitor including bucket vibrate that creates a slight vibrating action for precise control when dumping specific material or EH Precision Mode that allows for fine metering of bucket or boom movement
Set and store up to 10 different attachment configuration settings including flow, responsiveness, and other modes through the monitor for the most frequently used attachments in your fleet
SERVICE IMPROVEMENTS AND CAPABILITIES TO KEEP THE LOADER WORKING ALL DAY
