John Deere enhances its wheel loaders

Published on 25 March 2014

John Deere’s (JD) K-Series 4WD Wheel Loaders now feature three models that meet Final Tier 4 emissions standards, according to the company.

The engine update also allowed the company to offer several machine enhancements to the 624K, 644K, and 724K for added durability, productivity, increased uptime and lower daily operating costs.

The implementation of a JD PowerTech EPA Final Tier 4/EU Stage IV engine delivers impressive torque 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 new wheel loader models weigh the same as their Interim Tier 4 predecessors with no increase in machine dimensions. In addition, there is no impact on visibility going from an Interim Tier 4 to Final Tier 4 engine.

The K-Series boasts several axle improvements for increased durability in demanding conditions, including standard axle cooling and filtration, along with brake retractors and adjustors on the Teammate V axles.

Standard axle cooling and filtration keeps axle oil and its components cooler in hard breaking and significant load-and carry applications.

For added protection, axle oil is filtered by continuously cleaning wear particle and debris out of the oil. Together, this system provides increased engine reliability, durability and longevity.

Finally, brake reactors and automatic self-adjustors were added to eliminate brake drag and to maintain a constant brake running clearance with better compliance and less heat.

The K-Series 4WD utility models feature a standard five-speed lockup torque converter transmission that improves productivity and fuel efficiency.

This feature connects the entire drivetrain directly to the engine to provide full engine power during transport, ramp climbing and downhill conditions, eliminating wasted energy and excess fluid consumption by 5 to 8 percent, depending on the application.

The new models also come standard with several features to make the operator’s job easier, including a Level 1 Sound Suppression Package and quiet cab with air conditioning.

The Level 1 Sound Suppression reduces engine noise heard by the operator, which decreases fatigue and increases productivity on jobsites in areas that have noise restrictions.

Quiet cab provides ready to work climate control for maximum comfort in all seasons, and also keeps windows clear of ice and humidity to keep the operator up and running.

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.  FG
