John Deere 640L-II Cable Skidder

240-degree rotating seat with electrohydraulic (EH) joystick controls

Overhead view of the operator station

Designed by loggers for loggers, the quiet, spacious cab helps keep you more comfortable and productive – so you can boost your bottom line. The 4 m² (43 sq ft) of window area, coupled with the 240-degree rotating seat, maximizes visibility to the task at hand while minimizing neck strain. Armrest-mounted electrohydraulic (EH) joysticks provide smooth and intuitive control of all machine functions at your fingertips. The EH joysticks also allow you to customize the button and lever layout to your preference and saves your settings when switching between operators.

• Large windows provide clear visibility to the drag
• Rotating seat allows you to operate the machine while facing the front or rear
• Optional light-emitting diode (LED) lights allow you to start earlier and work later
• Customizable joystick patterns for multiple operators
• Optional heated seat with leather trim

Continuously Variable Transmission (CVT) used in L-II skidders

Offering loggers the best of both worlds, the Continuously Variable Transmission (CVT) combines the efficiency of the direct-drive transmission with the smoothness and ease of a hydrostatic drive. Delivering efficient power to the ground, the CVT automatically senses the load before delivering more torque to maintain the operator's wanted speed. The CVT also eliminates the need to shift gears, which shortens the learning curve for new operators, and helps the experienced pros maximize productivity.

• Constant engine speed helps provide superb multifunction performance
• Easy to operate, especially for new operators
• Defined ground speed limiters allow you to control your operating speed
• No need to shift gears

Removable engine panels and swing out coolers

Optional electric pump for filling hydraulic fluid

Fuel and diesel exhaust fluid (DEF) fills located on the same side of the machine. Grease banks are also located near the DEF fill.

Easy access to service components helps confirm daily checks and perform any scheduled maintenance, which ultimately minimize unexpected downtime and costly repairs down the road. The L-II lineup of skidders feature removable engine panels for wide-open access to filters and fluid level checks. Swing out cooler doors and an automatic reversing fan provide effortless cleaning of debris from the coolers. Fluid fills including fuel, DEF, and hydraulic oil can all be easily accessed from ground level, as well as daily greasing points.

• Ground level daily maintenance
• Swing out coolers for quick and easy cleaning
• Detachable engine panels
• Remote diagnostics via John Deere Connected Support
• Wiring and hose routings are protected against debris intrusion
• Simplified routing of the electrical and hydraulic systems
• Extended filter-change interval for hydraulic filter service
