The 437E knuckleboom loader is the latest addition to John Deere's full-tree system solutions.
This Tier 4 Final compliant E-Series upgrade is taking place one year after the release of John Deere's new L-Series skidders and wheeled feller bunchers and M-Series tracked feller bunchers and tracked harvesters. The new 437E delivers a five percent increase in both swing torque and boom lift over previous models, which allows for more productive delimbing and truck loading times. It uses a 127 kW (173 hp) Final Tier 4 engine that uses the same reliable FT4 after treatment used in the 700K forestry crawler dozers. The 437E also uses the same hydraulic system that has proven to be reliable on previous models.
Operators and maintenance personnel will be impressed with the new levels of serviceability found in the 437E. 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 servicing and more time being productive. Additionally, an optional electric refill pump simplifies servicing even further. The hydraulic oil reservoir capacity has been reduced from 300 to 130 litres (80 to 35 gallons), reducing the cost of changing hydraulic oil by 44 percent. Additional improvements include faster and easier CB radio installation and an updated electrical system. Integrated circuit boards replaced the fuse panel and relay board, improving reliability by eliminating relays and allowing a large 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. These allow the machine, the job site and the John Deere dealer to be brought together to help loggers better manage their equipment and operations. Source: http://search.deere.com/DDC/en_US/News/
