Sealed-switch module (SSM) consolidates many switches in one location, eliminating numerous unsealed connections and mechanical rocker switches, for maximum durability.
It’s 25 percent roomier, 50 percent quieter, and the front windows are 21 percent larger. It boasts a more efficient HVAC system, operator-configurable controls, and plenty of storage space. Operators can configure controls to personal preference, assigning specific functions to certain buttons or joystick controls through the monitor. Optional joystick and foot controls deliver smooth low-effort control to help reduce fatigue over long shift.
A Cut Above
Combining up to 11 percent more horsepower, 12 percent faster cycle times, and a best-in-class power-to-weight ratio, along with a new push-button Quick Dump function, these hard workers provide the muscle and finesse you need to jumpstart productivity in the woods. With the one-button Quick Dump feature, simply press a button to open both the accumulating and grab arms simultaneously, releasing trees from the pocket. Head-tilt and arm functions are combined into a single, smooth motion, minimizing fatigue while improving productivity.
More Stable, More Able
Optimal weight distribution and longer wheelbase improve balance, for better stability when climbing hills and controlling trees.
Powerful, fluid-efficient FT4 engines
Our FT4/Stage IV diesel engines meet emission regulations without sacrificing power. With over 60.5M John Deere FT4 test hours, the solution delivers the best combination of performance, efficiency, and reliability. Our emission-control technologies include cooled exhaust gas recirculation (EGR), smart exhaust filters, and selective catalytic reduction (SCR). These technologies are simple, fluid efficient, fully integrated, and fully supported.
Disk-Saw Felling Heads for Every Need
A choice of three different felling heads for the 643L and 843L. By matching the right felling head to your application, tree type, and conditions, you can improve productivity while extending the life of the carrier. The L-Series boasts up to a 21 degree improvement in tilt forward functions and a 2 degree improvement in tilt back; providing for better stability and bunch control.
Durable heavy-duty uptime-improving axles help deliver stability and hill-climbing power under the toughest forest conditions.
More Power, Better Stability & Increased Tractive Effort
Engine power has increased significantly – by 25 percent for superb multifunction performance. Longer, wider undercarriage maximizes stability no matter the terrain. Up to 45 percent more tractive effort increases capability for negotiating difficult or steep terrain, deep snow, and swamps.
Rapid Cycle System
RCS, now standard, uses a single, easy-to-operate joystick to quickly and simply control all boom functions. This dramatically reduces operator fatigue while increasing efficiency and productivity. RCS can be tailored to individual skill levels and specific harvesting conditions, from large single-tree harvesting to high-speed, multistem cutting.
Closed-Loop Hydrostatic Drive
Boost multi-functioning even more, particularly on slopes and in rough terrain. Adjust priority between track drive and other hydraulic functions to match site conditions and your operator style or preference.
Operate In Comfort
The new operator station was designed by loggers for loggers. It's roomier and more comfortable, with more ergonomically designed controls – fully adjustable armrests, including mounted keypads, providing fingertip control of all machine functions. Fully adjustable air-cushioned seat provides exceptional daylong comfort in the climate-controlled cab. And the view has to be seen to be believed – 44 percent more window area, providing an outstanding view of the cutting area.
Robust Booms/Felling-Head Combinations
Field-proven boom design is transplanted from our larger 900M- and 900MH Series models. All booms are stronger and more robust, with thicker plates and larger pins and bushings to ensure long life. A variety of boom sets and felling heads can be combined to optimize productivity across a wide range of conditions.
Larger Fuel Tanks
Fuel-tank capacity has been increased by over 50 percent (230 vs. 154 gal. on comparably sized machines) to extend intervals between fill-ups, allowing you to run up to 24 hours without refueling.
Easy access to service components helps ensure daily checks and preventative maintenance gets done on schedule, minimizing costly repairs down the road. Hydraulic reversing fan automatically reverses airflow to eject debris from the cooler cores, conserving power and fuel. Variable-speed fan runs only as fast as needed, or if conditions demand more frequent cleaning, simply press a button to actuate the reversing cycle.
Rapid Cycle System
New optional RCS uses a single, easy-to-operate joystick to quickly and simply control all boom functions. This dramatically reduces operator fatigue while increasing efficiency and productivity. RCS can be tailored to individual skill levels and specific harvesting conditions, form large single-tree harvesting to high-speed, multi-stem cutting.
Longer, wider undercarriage maximizes stability in all terrain conditions.
Robust Boom-Set / Attachment Combinations Provide More Swing Torque
Robust boom sets with thick plates and larger pins and bushings bolster reliability and help ensure long life. A variety of felling and harvesting heads can be combined to suit a wide variety of applications. Swing torque has increased up to 13 percent on the MH-Series Harvesters, providing more power to produce productivity.
Improved Cutting Swath
The 900M- and MH-Series maintain the improvements introduced on the 900K-Series machines, including a 30 percent increase in cutting swath, from 3 to 4 m (10 to 13 ft.), on the standard boom, and by eight percent, to almost a foot, on the harvester boom. For more cuts with less machine movement.
Go Bigger. See More. Do More.
Operators will find their comfort zones and be more productive in the roomier operator station. Controls are ergonomically designed. Fully adjustable armrests, including mounted keypads in the harvesters, provide fingertip control of all machine functions. Optional fully adjustable, suspension seat provides exceptional day long comfort in the climate-controlled cab. And the view has to be seen to be believed – 22 percent more window area provides an outstanding view to the cutting area.

We upped the ante. You wrote the rules.
Customer Advocate Groups provided us with real-world insight to create machines built for the way you work, while they redefine the meanings of uptime, productivity, and low daily operating costs. Then we tested them until we got them exactly right. Introducing the new game changing Feller Bunchers from John Deere.
L-Series Wheeled Feller Bunchers
These machines feature robust hydraulic and electrical systems designed to help keep your operation up and running, and boost your bottom line.
Simplified Serviceability Daily service checks, including fluid levels and greasing, are easier on an L-Series. Grouped service points also simplify daily maintenance. Fresh-air cab filter is quickly serviced from ground level. Plus large panels are easily removed for wide-open access to the engine compartment, and the cab tilts to provide quick access to other components.
Proven Components The 800s and 900s share many common components – including the engine, undercarriage, booms, and cab – simplifying maintenance and repairs when needed.
Remote Diagnostics When equipped with JDLink™ fast, accurate, remote diagnostics and rapid service response with the right part the first time, industry-leading parts availability, and dealer support are always within easy reach.
