John Deere plans new emissions upgrades on K-Series wheel-loader line

John Deere said recently that it will be updating its K-Series loader vehicles to keep in line with the Environmental Protection Agency's (EPA) Final Tier 4 emissions standards.

Specifically, the 444K, 524K and 544K wheel loaders will receive a PowerTech diesel engine that is within the Environmental Protection Agency's (EPA) Final Tier 4 (FT4) and the European Union's (EU) Stage IV regulatory requirements.

The engines can provide up to 163 horsepower in the largest model, the 544K, and the company said the engine will allow operators to effectively run the vehicle in most climatic and environmental conditions. 

"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 up-time, including easier daily checks and maintenance access, and the ability to work in all areas — regardless of air-quality conditions," Chris Cline, product marketing manager for utility-wheel loaders at John Deere Construction & Forestry, said. "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 up-time, and unmatched serviceability. Our customers can do more with these machines."

The vehicles also come with torque-converter transmission that continuously monitors speed and loading conditions. Improvements also offer increased acceleration ability, as well as fuel and power efficiency, when operating in the higher gears. Each vehicle also has on-board diagnostics that the company said will provide information to operators on the loader's functionality and can lead to more efficient upkeep and repair service.
