Deere introduces E-series knuckleboom loader

The E-Series knuckleboom loaders feature several productivity-enhancing improvements to keep loggers working strong all day. Most noteworthy, the 437E delivers a five per cent increase in both swing torque and boom lift over previous models for more productive delimbing and truck loading times.

“These machines are very well-built, and they represent pretty much everything we asked Deere for,” said Buddy Lominick, Jr., John Deere CAG member and vice president of Big Pine Logging in Newberry, South Carolina. “The improved boom speed and lift capacity really help out our production — these small changes make a big difference.”

Understanding that lost production time is lost revenue for loggers, John Deere made several updates to the E-Series with uptime in mind. The 437E boasts a 173 horsepower Tier 4 Final engine that uses the same after-treatment system as the 700K forestry crawler dozers, providing the reassurance of a proven system.

The 437E boasts improved serviceability as well. A ground-level oil drain and filter change make hydraulic oil and filter maintenance much faster and safer, allowing operators to spend less time on service and more time being productive. Additionally, an optional electric refill pump simplifies service even further. The hydraulic oil reservoir capacity has been reduced from 80 to 35 gallons (approx. 303-135L), reducing the cost of changing hydraulic oil by 44 per cent. Additional improvements include a faster, easier CB radio installation and an updated electrical system. Integrated circuit boards replaced the fuse panel and relay board, offering improved reliability by eliminating relays and a dramatic reduction of wiring and connections in the circuit board area.

All John Deere knuckleboom loaders come standard with the JDLink machine monitoring system and remote diagnostics as part of the John Deere ForestSight package of customer-driven technology solutions that bring the machine, the job site and the John Deere dealer together to help loggers better manage their equipment and operations.
