The John Deere 900M-Series tracked feller bunchers and 900MH-Series harvesters are now equipped with Tier 4 Final engines.
John Deere’s Tier 4 Final engines offer a Diesel Particulate Filter (DPF) solution that is known for its ability to reduce the dependency of Diesel Exhaust Fluid (DEF).
“Out in the woods, machine productivity and uptime are crucial to business success. Our FT4 engine and emission solutions have been rigorously tested in the most extreme applications. Loggers can be confident that their tracked feller buncher or harvester can withstand even the most challenging conditions,” said Jim O’Halloran, product marketing manager for John Deere.
“As a proven partner offering the most comprehensive solutions in the industry, John Deere is proud to offer loggers a powerful, reliable machine that meets current and future emissions standards.”
With the required emissions change, John Deere claims the engines maintain power density, torque and transient response.
In addition to improved fuel economy, the design of the engine after-treatment system results in low DEF usage.
“DEF usage has become a real input into the planning and cost of the overall equipment operation,” O’Halloran said.
“We have to talk about overall fluid economy now, and if you use less fluid, there is less handling and storage requirements. It’s a real positive factor in the efficiency and overall bottom line of our customers.”
John Deere has also made changes to its equipment line-up, by improving the structure, design and horsepower on select machines.
Deere offers three 900M-Series tracked feller buncher models, the 903M, 953M flat bottom and 959M leveling machines, as well as two 900MH-Series harvesters, the 953MH flat bottom and 959MH levelling machines.
All of the 900M-Series and 900MH-Series machines now feature a redesigned engine enclosure, to improve structural strength.
In addition, all of the 900M-Series and 900MH-Series machines now boast 330 hp, the 959M Feller Buncher and 959MH Harvester continue to have best-in-class levelling envelope, maximizing operator comfort and performance requirements in demanding steep slope logging applications.
Other updates include an improved LED work lighting option, and the expansion of the disc saw felling head option availability. This includes the 56 cm felling head, which is now available for all of the 900M-Series tracked feller bunchers.
The John Deere M-Series and MH-Series machines are available with JDLink five years in base.
JDLink remotely connects owners and managers to their machines and dealers, providing alerts and machine information to better manage where and how equipment is used.
