2008 John Deere Forestry Press Release

MOLINE, Illinois (August 20, 2008) - John Deere introduces the D-series Swing Machines, including three purpose-built models — the 2154D, 2454D and 2954D. Engineered to withstand the toughest forest environments, the D-series features “next-size-up” swing systems, a new boom base design, and a smart cooling package — all designed for improved durability, productivity, and low maintenance costs. 

Each durable D-Series model features a swing system sized with larger components for extended life and Deere’s smart cooling package which includes a hydraulically-driven, on-demand fan with reversing option for debris management that keeps the machines productive. The fronts have been re-designed, the upper frames strengthened and the boom pin tolerances have been improved, resulting in increased durability.

D-series key features include:

• Purpose-built upper frame with a stronger boom and bearing mounting area
• Solid under-decking with removable service panels
• Durable track chain with increased strength
• Efficient hydraulic system that automatically matches the power output to the load
• Powerful arm strength for optimized lift capacity on log loaders
• Standard 277-gallon fuel tank allows for extended run times between fill-ups
• Best-in-class Waratah Forestry Attachments

John Deere designed the cabs to increase productivity and operator comfort. Based on the application, cabs come mounted on either a 7-in. (178 mm) fixed or 48-in. (1,219 mm) hydraulically tilting riser for ease of entry. All cabs have easily accessible joystick controls and switches, and sightlines that enable maximized worksite visibility. A rear-entry cab is optional.

The D-series is appropriate for harvesting and processing, as well as road building or shovel logging. Several configurations, including Road Builder, Processor, Live Heel Loader, BNT Loader, Power Clam, or Delimber Carrier are available for different customer applications.
