The 444K, 524K and 544K Tier 4 Final utility-class wheel loaders are designed for jobs that demand extra agility and ability on the jobsite. “The goal in updating our K-Series utility wheel loaders was to build upon the reliable platform of the previous models, while offering more customer-inspired productivity features to increase uptime, including easier daily checks and maintenance access and the ability to work in all areas – regardless of air quality conditions,” said Chris Cline, product marketing manager for utility wheel loaders, John Deere Construction & Forestry.
The implementation of John Deere PowerTech EPA Tier 4 Final diesel engines enables operators to work anywhere, even in nonattainment areas. The PowerTech engine delivers impressive torque – 444K (124 hp), 524K (141 hp), 544K (163 hp) – to help maintain good boom and bucket speed in and out of the pile for heaped loads, even in wet or hard-packed material.
The K-Series loaders implement excavator-style hydraulics that sense the load and deliver the flow needed for smooth combined functions and fast work cycles. A PowerShift torqueconverter transmission employs Smart- Shift technology to continuously evaluate speed and load conditions. The 544K’s new standard five-speed transmission with lockup torque converter in gears 2–5 offers increased acceleration, speeds cycles, and optimizes power and fuel efficiency during transport, roading and ramp climbing.
Cab improvements include an enhanced multifunction monitor with diagnostic and maintenance information, tinted glass and a Level 1 sound suppression package.
To eliminate downtime, the K-Series models are equipped with remote battery terminals for faster and easier jump-starting. The engine compartment can remain closed and locked to charge the batteries, which reduces the threat of vandalism. These machines also feature an optional right-side platform and steps for easy access to the right side of the machine.
