Improvements to the machine boom structure directly result in increased productivity. The design increases visibility to the coupler, bucket or forks, reducing overall cycle times, material spillage and equipment damage. Additional bucket options include enhanced production buckets with integrated spill guards, profiled side cutters and greater rollback, improving bucket fill and material retention. A new shaft-style fork design offers more visibility and tine length options, including 48-inch, 60-inch and 72-inch. Smoother boom and bucket hydraulic kickouts reduce operator fatigue, while new standard parallel lift linkage improves load leveling, limits bucket spillage and increases fork operation speed.
Return-to-dig settings can now be set from the cab for both directions of the bucket, allowing operators to return-to-dig from any position without having to adjust the bucket to dump position. Boom and Bucket EH metering rate aggressiveness allows the operator to choose a setting — low, medium or high — for quicker hydraulics or reduced response in precision operations for improved comfort. Attachment configuration settings can be saved, allowing the operator to assign and save settings to an attachment, making it easier to switch between attachments without impacting productivity.
The 524L, 544L and 624L are available with optional High Lift (HL) and High Lift Plus (HL Plus) selections; there is also a tool carrier option on the 524L and 624L models. The HL Plus option features hinge pin heights that are 12 to 13 inches higher than current HL pin heights, allowing the operator to dump into higher trucks or wagons. The tool carrier option provides the best centerline visibility to the coupler or forks. It is ideal for customers handling materials, like pallets, pipe or logs, where centerline visibility is important.
From a service perspective, the hydraulic hose and electrical wire harness routing and retention are improved, and the machines feature 40 fewer leak points, lowering potential repair costs.
The 524L, 544L and 624L feature fuel-efficient Final Tier 4 John Deere diesel engines (6.8 liter) and boast 152 (113kW), 166 (123kW) and 192 (143kW) net peak horsepower, respectively.
Fleet managers looking to get the most out of their L-Series wheel loaders can rely on their John Deere dealers to provide Ultimate Uptime, featuring John Deere WorkSight™. With Ultimate Uptime, owners receive predelivery and follow-up inspections that include five years of JDLink™ telematics, machine health prognostics, remote diagnostics and programming capabilities and the ability to add dealer-provided uptime solutions to a customized package.
The 544L will also be on display at World of Concrete, Jan. 22-25, 2019, at booth C5451. Along side the 544L will be a JD544, built in December 1968, to commemorate 50 years of John Deere building wheel loaders. Contractors, builders, and sand and gravel-pit operators alike helped build the innovative JD544 50 years ago. The new L-Series machines are a testament of durability, dependability and productivity, and of continuous customer-inspired design. Throughout 2019, all new manufactured wheel loaders will showcase a 50 year anniversary emblem to signify this milestone.
