ENGINE

PowerTech™ diesel engine6.8-L PowerTech™ diesel engine delivers a productive combination of power and torque. Our IT4/EU Stage IIIB technology is simple, fuel efficient, fully integrated, and fully supported. It employs field-proven cooled exhaust gas recirculation (EGR) for reducing NOX, and a diesel particulate filter and diesel oxidation catalyst to reduce particulate matter. Periodic active and passive regeneration automatically cleans the filter without impacting machine productivity.Quad-Cool design isolates coolers from engine heat Quad-Cool design isolates coolers from engine heat for increased efficiency and durability, and keeps them well protected behind the heavy-duty grille and fan. Three-millimeter perforations act as a “first filter,” preventing entry of most airborne debris.Hydraulic-driven variable-speed fanHydraulic-driven variable-speed fan runs only as needed, reducing noise and fuel consumption. Reversing option automatically back-blows cooler cores at preset intervals. When conditions demand more frequent cleaning, simply press a button. Wet-sleeve liners Wet-sleeve liners provide uniform engine cooling and longer durability than cast-in-block designs.

FILTERS

Diesel particulate filter Diesel particulate filter is easily removed for maintenance. Minimum service interval is 5,000 hours and can be done by your John Deere dealer.Exhaust filter operation and statusOn-screen displays indicate exhaust filter operation and status. Diagnostic monitor also records service intervals and provides easy-to-understand service codes to help speed troubleshooting.Vertical filtersVertical filters allow quick, no-spill changes. Engine, hydraulics, and transmission utilize a common oil, further simplifying service.

HYDRAULICS

Hydraulic systemsSeparate, completely sealed hydraulic and hydrostatic systems with common fluid and filter codes eliminate the possibility of cross-contamination, leaving you with fewer maintenance issues to worry about.In-cylinder sensors In-cylinder sensors eliminate external linkage, enabling return-to-dig, boom-height kickout, and bucket leveling. Setting them is push-button easy from the seat. These standard features, plus boom float, help speed cycles in repetitive applications such as truck loading.Cylinder protection The K-Series crawler loader offers optional cylinder protection. Guards protect the boom and bucket cylinders from falling brush, debris, and material spillage. Additional cylinder guards are available for the multi-purpose bucket.

CAB COMFORT

Spacious cabSpacious cab is a welcome departure from the cramped quarters in other loaders. Entryways are wide, and user-friendly pull-type latches ease entry and exit. Viscous cab mounts, rear acoustical glass, and extensive insulation effectively isolate operators from vibration and noise. At just 78 dBA, the cab is noticeably quiet.High-back air-suspension seat Standard high-back air-suspension seat and optional deluxe heated and leather-bolstered lower cushion adjust multiple ways for daylong comfort and support. Arm- and footrests also adjust. Operators will find plenty of space to stow beverages, a cooler, and other carry-ons.Air conditioning Air conditioning is standard. Numerous directional vents keep the glass clear and interior comfortable. Pressurized cab helps keep dust out.

EASE OF CONTROL

Choose what fits your operator’s style Joystick FNR or V-pattern transmission lever with steering pedals? Single-lever joystick or two- or three-lever hydraulic controls? Choose the arrangement that best fits your operator’s style. It’s yet another example of how we respond to your needs. Sealed-switch module Sealed-switch module gives fingertip control of keyless start, and enables exclusive features such as turbocharger cool-down and auto shutdown. Touchpad security system requires a numeric pass code (when enabled) to prevent unauthorized operation.Return to dig Return to dig allows an operator consistent and precise control of bucket angle. This is good for making accurate, level cuts into a pile or hill. Instead of watching a mechanical guide for consistent bucket position, it allows an operator to pay closer attention to maneuver the machine.Boom height kick-out Boom height kick-out allows an operator to set a (maximum) boom height for consistent control of boom/bucket height. This function is extremely useful to speed production in repetitive loading applications.

STRUCTURE

Scarifier Unlike scarifier versions found on other crawler loaders, our optional triple-shank ripper is designed for serious business.4-in-1 Multipurpose bucket Want to put even more work within reach? Add a 4-in-1 multipurpose bucket for loading, bulldozing, spreading material, and handling cumbersome objects.Lower bucket pinsLower bucket pins are lifetime sealed and lubricated.

EASE OF SERVICE

Large service doors Large service doors open wide, and same-side daily checkpoints are conveniently grouped for ground-level access. Engine, hydraulic, and coolant checks and refueling can be done quickly without climbing on the machine. Plus, an under-hood light helps show the way.Operator station tilts a full 53 degreesOperator station tilts a full 53 degrees in minutes, for wide-open component access.Hinged butterfly-style belly pan Hinged butterfly-style belly pan folds down, providing easy service access to the oil pan. Fluid-sample and diagnostic test ports Fluid-sample and diagnostic test ports simplify preventative maintenance work and troubleshooting.Optional quick fluid-service ports Optional quick fluid-service ports help speed changes. 2,000-hour hydraulic/transmission, 1,000-hour engine coolant, and 500-hour engine oil-service intervals minimize maintenance
