WHEELED FELLER BUNCHERS 643L / 843L

YOU RAISED THE BAR. WE CHANGED THE GAME.

m'Wr'W figg A /.?; v- / ■:■ '■■■“.< ', ' v- ■ ' TO DEVELOP THESE NEXT-GENERATION MACHINES, we met with loggers all over the world — the ones who live it every day. Our customers spoke. And we listened. Through Customer Advocate Groups (CAGs), we collected fresh insight on what works and what doesn't. Over 250,000 engineering hours, combined with over 11,500 hours of testing in everyday, real-world conditions, ensure these machines are our most reliable and productive ever. These new wheeled feller bunchers redefine uptime, productivity, and low daily operating costs. And...

BUILT TO THE HILT Never lets up. Or lets you down. You need a machine that works as long and hard as you do. L-Series Wheeled Feller Bunchers feature robust hydraulic and electrical systems designed to help keep your operation up and running, and boost your bottom line. Simplified electrical system Sealed-switch module (SSM) consolidates many switches in one location, eliminating numerous unsealed connections and mechanical rocker switches, for maximum durability. Tougher pins, bushings, and hydraulic cylinders Pins and bushings on the booms and masthead are more robust, for longer life....

STANDOUT FEATURE Redesigned cab and ergonomics. Designed by loggers for loggers, the updated cab is signifcantly quieter. It’s roomier and more comfortable, too, boasting a more effcient HVAC system, operatorconfgurable controls, and plenty of storage space. Larger, quieter cab Confgurable controls The spacious, comfortable cab is 25-percent larger, with half the noise. And 21-percentmore front window area dramatically improves visibility. Smooth, one-of-a-kind electrohydraulic (EH)enabled controls allow operators to confgure joystick buttons to their own individualized preference. Optional...

What operator wouldn't be more productive in an L-Series Wheeled Feller Buncher? Combining up to 11-percent more horsepower, 12-percent faster cycle times, and 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. New one-button Quick Dump Simply press a button to open both 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...

Tiers without fears. You asked for the best technology choice to meet EPA Final Tier 4 (FT4)/EU Stage IV emission regulations, and we listened. We understand your concerns, so we’ve always focused on adding the right engine technologies at the right time. This smart approach to meeting emission regulations doesn’t compromise on power, reliability, or ease of operation. 60.5M TEST HOURS TOWARDS FT4

FT4 engines Our FT4/Stage IV diesel engines meet emission regulations without sacrificing power or torque. We built on our EPA Interim Tier 4 (IT4)/EU Stage IIIB solution to deliver the best combination of performance, efficiency, and reliability. These technologies are simple and fluid efficient. Low total fluid consumption John Deere FT4 engines maintain engine performance while minimizing total fluid consumption — diesel fuel plus diesel exhaust fluid (DEF). The exceptionally low DEF consumption rate reduces the need for DEF by four to six times compared to some other FT4 systems....

HEAD-TO-HEAD COMPARISON Disk-saw felling heads for every need. Deere offers you 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. FD45 - Open area between post for good tree visibility - High productivity in thinning applications - Deepest accumulation pocket (largest of the three), to improve productivity for thinning small trees - Best paired with a 643L for both fat and hilly applications in dry or muddy conditions FD55 -...

EASY MAINTENANCE Simplifed serviceability Grease-thru pins Daily service checks, including fuid levels and greasing, are easier on an L-Series. Grouped service points also simplify daily maintenance. Fresh-air cab flter 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. Reversing fan automatically reverses airfow at 30-min. intervals to eject debris from the cooler cores, conserving power and fuel. Variablespeed fan runs only as fast as needed, or if...

Wide-open access to cooling package Cooling fan and other cooling system components swing out for quick and easy cleaning. Air-intake compartment is sealed off from the engine compartment to keep things cool. Auto-idle automatically reduces engine speed after an operator-configurable interval of inactivity, reducing fuel consumption and noise, while extending component life. Auto shutdown turns off the engine after a preset length of time, further reducing engine wear and fuel costs. Extended filter-change interval Hydraulic filter service has been extended from 2,000 to 4,000...
