John Deere continues to update its K-Series wheel loader lineup to adhere to Final Tier 4 emissions standards and better meet the needs of today's operators.

The 444K, 524K and 544K utility-class wheel loaders are designed for jobs that demand extra agility and ability on the jobsite or at the farm.

"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.

"Whether you are a road builder, site developer, landscaper, or running a cattle or dairy operation, the new utility loaders provide best in class stability and hydraulic controls, maximum uptime, and unmatched serviceability. Our customers can do more with these machines."

The implementation of a John Deere PowerTech EPA Final Tier 4 (FT4)/EU Stage IV diesel engine 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 torque-converter 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 optimises power and fuel efficiency during transport, roading, and ramp climbing.
