Designed to meet the most demanding specs — yours.
Inspired by input from owners and operators across North America, the re-imagined 755K Crawler Loader is loaded with productivity- and uptime-boosting enhancements. Like an ultra-quiet, completely redesigned operator station. More control choices. An innovative on-demand cooling system with optional hydraulic reversing fan. And quicker daily, and less frequent, periodic maintenance. Plus its EPA Interim Tier 4 (IT4)/EU Stage IIIB engine meets rigid emission standards, so you can work the 755K wherever there's work, even in nonattainment areas.

6.8-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 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 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 provide uniform engine cooling and longer durability than cast-in-block designs.
Diesel particulate filter is easily removed for maintenance. Minimum service interval is 5,000 hours and can be done by your John Deere dealer.On-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 filters allow quick, no-spill changes. Engine, hydraulics, and transmission utilize a common oil, further simplifying service.
Separate, 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 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.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.
Spacious 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.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 is standard. Numerous directional vents keep the glass clear and interior comfortable. Pressurized cab helps keep dust out.
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 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 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 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.
Unlike scarifier versions found on other crawler loaders, our optional triple-shank ripper is designed for serious business.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 pins are lifetime sealed and lubricated.
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 degrees in minutes, for wide-open component access.Hinged butterfly-style belly pan folds down, providing easy service access to the oil pan. Fluid-sample and diagnostic test ports simplify preventative maintenance work and troubleshooting.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
This easy-to-use, comprehensive suite of technology increases uptime and productivity while lowering operating costs. JDLink™ machine monitoring provides real-time machine utilization and health data, plus location information. Fleet Care proactively suggests maintenance to correct problems early before they create costly downtime. Service ADVISOR™ Remote enables your dealer to read diagnostic codes, record performance data, and even update software without a trip to the jobsite.
Multi-language monitor provides a wealth of machine info in addition to vital and general operating conditions. You can even “customize” forward/reverse ground-speed ranges, steering modulation, FNR shift rate, and forward/reverse speed ratios.Total Machine Control (TMC) allows you to customize operating characteristics and response, for superb, one-of-a-kind control. TMC can also be used to monitor machine readings such as mileage and hours.
John Deere was the first North American dozer manufacturer to utilize dual-path hydrostatic drives in 1976. These dozers feature 30 years’ experience of unmatched best-in-class dual-path hydrostatics with counter-rotation, infinite speed control, live power turns, counter-rotation, and dynamic braking.Counter-rotating tracks boost maneuverability on crowded jobsites with space-saving spot turns. It’s a productivity advantage that also works well for overcoming heavy corner loads and for quickly repositioning the bucket on the go.Infinitely variable speed control lets you increase or slow power to either track, for smooth moves around structures and on soft terrain. Power management takes the guess and work out of efficient operation. Simply set the maximum ground speed and the system does the rest, automatically maintaining peak engine power and efficiency without stalling or shifting.
Exceptionally durable undercarriage features unitized track frames with mainframe-mounted planetary final drives for maximum uptime. Cleaning the undercarriage has never been easier. Specially designed, guarded, and sloped track frames resist buildup and ensure quick and easy clean-out when needed.Their six-roller track frames and optimized centers of gravity makes this crawler loader a highly stable machine.Heavy-duty undercarriage features deep-heat-treated, sealed and lubricated track links and through-hardened, sealed and lubricated rollers for maximum wear resistance.To further increase durability and decrease operating costs, opt for the Maximum Life Undercarriage and Extended Life Bushings.
